Inspection of Transfer Chains and Drive Belts  

Let’s start with the transfer chain: 

Clean Transfer Chain: Begin by cleaning the transfer chain to facilitate an easy inspection a clean surface allows for an effective assessment and helps maintain the seamer’s performance. 

Inspect Wear Strips: Carefully inspect all wear strips for the transfer chain. Any signs of wear or damage should be noted, fasteners should be  present and secure, and replacements should be made promptly to maintain optimal function. 

Adjust Transfer Chain Tension: Ensure that the transfer chain is adjusted to the proper tension. Proper tension is crucial for smooth operation and accurate seaming. 

Assess Transfer/Chain Fingers: Check the transfer/chain fingers for sharp edges or damage. Any issues found should be addressed immediately to prevent potential problems during the seaming process. 

Verify Synchronization: Verify and record the synchronization at the filler transfer and at the can make-up in the seamer . This step ensures precise operation and optimal seam quality. If you need parts or have questions about specific chain tolerances, feel free to reach out to us. 

Now, let’s move on to the drive belts: 

Assess Belt Condition: Examine the belts for any signs of stretching or cracking at the filler and lid separator, if applicable. Damaged belts should be replaced to prevent unexpected breakdowns and maintain consistent performance. 

Synchronize Driven Assemblies: Ensure that all driven assemblies are synchronized properly. Proper synchronization enhances the can seamer’s efficiency and reliability. 

Align and Tension the Belt: Align the belt and adjust its tension to the manufacturer’s specifications. This step is important to achieve consistent seams and optimal results. 

Chuck and Rolls

Let’s address the chucks and rolls. By now, your seaming technician team is probably following our daily maintenance checklist for your can seamer. If any chucks or rolls showed premature wear or are trending towards failure during the daily check, it is crucial to replace them promptly. By taking proactive measures, you can prevent further damage and maintain the machine’s performance. 

Now let’s focus on your weekly maintenance check for chucks: 

Use a Dial Indicator: Use a dial indicator to record the current plane of all machine stations. This consistency and tight tolerance are critical for achieving consistent seams.  

Does your team need can-seam analysis training? We’ll teach them how to identify can damage and how to prevent it. Schedule your training today. 

Verify and Record chuck plane: Using your dial indicator, verify and record each station starting with 1, indicating the amount of variation between each station. Optimal setup should be +- .001 .  Accurate records allow you to track changes over time and address any issues promptly. 

Verify Knockout Pad: Asses all K.O. Pad conditions for any type of damage. Then using your RSS MACLIN Pin Gauge record all machine stations and adjust the height if outside of OEM Specification. Note: If any chucks are replaced, verify that the KO pad is seated and secured properly. Take care not to over-torque, as it can lead to potential problems during operation. Then set to proper height. 

For rolls:  

Assess Roll Rock: Using your dial indicator, assess the roll rock on all remaining first and second operations to ensure it is less than .002. If the roll rock exceeds .002, it’s important to replace the roll to maintain precise seaming. 

Assess Roll Condition: Assess the coating of the roll. While performing this inspection confirm there are no cracks, chips or grooves on the profile


During your daily maintenance check, did you find any signs of leaking lines? If you find leaks, confirm that all unions are tightened and secured properly. Proper lubrication is crucial for smooth operation and extended machine life. 

Ensure Lubrication Block Functionality: Verify that the lubrication block is functioning correctly(confirm the cycle pin and sensor.) If there are any faults, it might indicate a blockage or failure in the distribution block.  

Assess for Blockage: Assess whether the blockage can be cleared or if a replacement is needed. 

Audit the Condition of Oil: Regularly audit the condition of the oil, especially for signs of contamination, such as sugar, water, or product.

How to Make Your Changeover Like a Pit Crew

February 23, 2024

RSS Maclin

NASCAR has managed to shave the hours of car maintenance down to mere seconds. Like a race car pit crew, RSS MACLIN understands that on the can-seamer line, efficiency isn’t just convenient; it’s a necessity. Buckle up. In this blog, we’ll explore how we can make your can diameter changeover team operate like a pit crew.

At RSS MACLIN, we’re not stopping to refuel or change tires. We’re stopping the whole production line, which is just as disruptive. An average can diameter changeover for a can-seamer machine takes 8-12 hours. If you follow our lead, you can cut that tooling changeover down to four hours.


The Problem

When pit crews work on cars, they’ve got seconds to diagnose potential problems. At RSS MACLIN, the problems are different, but the clock is still ticking. That’s why we’re committed to solving the following problems as quickly and efficiently as possible:

Time-Consuming Changeovers

Installing change parts, especially those for can diameters, can be time-consuming. We’ll help you streamline this process by pinning your machine guide rails, using our Quick-Change Timing Plug and chain fixture and Oversized Hollow Plugs. Instead of spending time installing change parts, you can use that time and energy on the production line.

Risk of Equipment Damage

When the clock is running and you rush through changeovers, you run the risk of damaging your equipment. In fact, some machine parts that are susceptible to damage can affect the integrity of the seam. At RSS MACLIN, our expertise and SOPs (standard operating procedures) ensure proper handling and installation, minimizing the risk of costly equipment repairs or replacements.

Quality Issues and Production Delays

Can diameter changeover is one challenge. The ramp-up into full production is another challenge that can bring quality issues and delays in meeting production demand. At RSS MACLIN, we can enhance your quality control measures and reduce the downtime associated with ramp-up, because a meticulously thought-out process and execution beats a reactionary plan any day.

The Solution

At RSS MACLIN, we’re proud to provide can-seamer audits with 30% more inspection points than OEM. What’s more, we take a look at the entire packaging line (not just the seamer), the technicians, and the materials, to give you the most thorough can-seamer audit on the market.

The Crew

Part of what makes a NASCAR pit crew so successful is having the right person for the right job. They are a highly trained team that carries out specialized tasks like clockwork.

At RSS MACLIN, we can train your team to become can-seamer experts with our hands-on three-day training that is offered on-site.

The Material

At RSS MACLIN, our team efficiently stages can-handling parts for easy accessibility, while also using clear markings to identify parts and diameters. This helps reduce confusion and time searching for specific can diameter sizes to improve efficiency and guarantee a perfect setup every time.

The Process

A documented changeover process is crucial to minimize inefficiencies on your can-seaming line, by creating a clear path using a step-by-step method for repeatability and consistent results. This systematically removes more variables that can affect your perfect can seam and body


It can take can-seam teams an entire shift to change the can-handling parts and upwards of two shifts to optimize the new configuration for efficiency. With the right crew, material and methods, we won’t just have your can diameter changed in four hours, we’ll have you running at peak efficiency.

Let’s get efficient! Contact the can-seamer experts to develop the pit crew process your company wants when changing the can-seamer.

Part 1: Mastering Can-Seam Quality

August 21, 2023

How can-seam materials impact TPO 

Who can resist a breath of fresh mountain air? While oxygen benefits your body and mind, it’s not a canner’s best friend. In fact, total package oxygen (TPO) can affect both your canning materials and your machines. In this blog post, we’ll explore how can-seam materials can impact your total package oxygen levels and what you can do about it.  

But first:

What is total package oxygen?

At RSS MACLIN, we support everyone in the food and beverage packaging industry, from micro-breweries to carbonated beverage giants. For those new to the industry, total package oxygen is the amount of oxygen that is sealed in a package. For cans, this includes: 

  • Dissolved oxygen: The oxygen that is dissolved in the liquid itself 
  • Headspace oxygen: The oxygen within the foam of a carbonated beverage 
  • Oxygen transmission: Oxygen that slowly permeates through the walls of the can 

At RSS MACLIN, we’re committed to excellence. 

How do can-seam materials affect TPO levels?

The materials used for can seaming are important to ensure low TPO and a high-quality seal. When exploring how can-seam materials affect TPO, we’ll look specifically at the compound, can body, and seam specifications.  


Compound quality and consistency  

When you’re trying to ensure a quality seam on your can, compound is crucial. It’s a vital part of the sealing process and ensures an airtight and secure seam with low TPO levels. Be sure to check the consistency of the compound to ensure optimal quality, since that can also impact the quality of the seam and the TPO levels.  

Compound amount 

In addition to the quality of the compound, it’s also important to ensure the right amount of compound is applied to each lid. For the best results, apply 26-32 grams of compound, depending on the diameter of the lid.  

Can body  


In the food and beverage packaging industry, aluminum is the material of choice, often selected for its corrosion resistance and lightweight properties. Over time, aluminum cans are susceptible to oxygen transmission, where the oxygen passes through the material and into the can’s liquid, increasing the TPO levels. For this reason, it’s important to use materials that are new, as the age of the material can impact the TPO levels. At RSS MACLIN, we recommend using lids that are no more than 2 years old, so as not to compromise the quality of the seal.  

Total Package Oxygen (TPO) graphic

Can dimensions  

At RSS MACLIN, we know that details matter. When you ask for scheduled or emergency service, we look at more than just the equipment. Your can’s dimensions are crucial to accurately determine the pin height so that the can seam is shaped and sealed correctly. To calculate the pin height, use the following equation:  

Pin height = Raw can height – Chuck lip height – Material loss – Material deflection 

Seam specifications  

Curl height  

The can seam’s curl height can help minimize TPO levels and improve the quality and integrity of the seal. While curl height varies according to the can’s dimensions, it’s important that seam technicians regularly inspect the seam quality and adjust as necessary.  

Flange angle 

As a critical aspect of the seam, the flange angle provides strength to ensure that the seam is able to withstand the internal pressure of carbonated beverages without compromising the seal. If the flange angle isn’t correct, the seam could leak, leading to increased TPO, decreased freshness, and possible product contamination.

Take your can seams to the next level

Don’t let inconsistent canseam quality hold you back. Sign your team up for our hands-on canseaming training to learn how to inspect, identify, and correct issues to ensure ultimate product freshness and customer satisfaction.

5 Reasons Why Routine Machine Audits Are Crucial to Prevent Emergencies

August 7, 2023

RSS Maclin

With 75 years of can seaming experience, we understand the ramifications and cost of downtime in manufacturing. In this blog post, we’ll explore 5 reasons why routine machine audits are crucial to prevent emergency downtime, and what you can do instead. 

But first things, first:

Do you have a can-seamer emergency?

When your can seamers are down, contact RSS MACLIN. We’ll respond within 24 hours, so that you can get your production line up and running.  

But even when things are running smoothly, you don’t want to leave production to chance.

It can be challenging to control all of your can seamer processes so closely that you prevent all downtime, but that doesn’t mean that you have to plan production schedules to accommodate for unplanned production downtime.

When you schedule a routine machine audit with RSS MACLIN, we’ll help you to:

1. Avoid production downtime 

When cans are being sealed as fast as 70,000 cans per hour, time is money. Every minute of downtime counts, when you’re trying to fulfill a customer demand by a certain deadline.  

When your can seamer production is down, it’s easy to calculate the lost profit, but read one, and you’ll uncover some of the hidden costs.  

2. Avoid labor downtime 

Operators who are standing by during a can-seamer emergency are costing the company money, adding to the unexpected cost from lost production. Even when the unexpected happens, can-seamer training can help reduce your production downtime and help your line return to peak O.E.E.  

3. Avoid ingredient and material loss 

When your product line stops, it impacts your ingredients and materials. They can spoil or become contaminated. Sometimes, when the seaming process comes to a halt mid- production, defects in the can seam require the product to be thrown out.  

When you schedule a routine machine audit with RSS MACLIN, we can ensure that ingredient and material loss from unplanned can-seamer emergencies are kept to a minimum.  

4. Avoid production scheduling conflicts  

Production scheduling can turn into a nightmare when the line stops. It affects nearly every product line deadline. But plant managers don’t have to schedule to accommodate for unplanned can-seamer emergencies. Instead, a simple routine can-seamer machine audit can help keep the line flowing and the schedule on target.  

5. Avoid supply chain problems 

With so many companies relying on “just in time” inventory management practices, companies receive the exact amount of material, almost exactly when they need it. But problems arise when production lines aren’t humming. This can happen to both the receiving and the delivery end. It can result in too much raw material waiting to be used, and too many empty delivery trucks waiting to be dispatched. 

What does a routine can-seamer machine audit consist of?

At RSS MACLIN, our audit services include both diagnosis and repair of your can-seaming machinery. We’ll make the most of your scheduled downtime to address all of the parts along your production line (not just the can seamer), to ensure that your can-seaming production keeps running at peak O.E.E.

By encouraging your team to take ownership of their work and involving them in the optimization process, you tap into their valuable expertise and experience. By empowering can seam operators, they gain the ability to be self-reliant, taking charge of self-diagnosing issues and refining processes. As the “first responders” before technicians step in, operators play a crucial role in promptly identifying areas for improvement and boosting overall efficiency. This proactive approach ensures that the production line doesn’t suffer setbacks due to employee turnover, as operators and technicians are equipped to handle challenges and maintain operations smoothly.

 Quality Control and Inspection:  

To ensure the production of defect-free cans, it is essential to implement a robust quality control and inspection system. This system should diligently detect any abnormalities or defects in the seaming process, preventing the occurrence of hold-products. The can manufacturer’s specification sheet will provide recommended measurements for properly sealed cans, serving as a valuable reference. 

Regular inspections of the seams are crucial to identify any signs of improper sealing, such as leaks or loose ends. To enhance the inspection process, leverage advanced technologies like seam vision systems, which offer precise and speedy defect identification. By proactively catching and addressing issues at an early stage, you can minimize waste, guarantee product integrity, and uphold high efficiency throughout your can-seaming operation. 

It is worth noting that seam analysis is often overlooked or underutilized. To address this, ensure that multiple individuals are trained in seam analysis techniques. This allows for broader team involvement and ensures that seam analysis is performed consistently and effectively. By prioritizing comprehensive seam analysis, you can further enhance the quality control process and achieve superior results in your can-seaming operation.
