Core Quality - Something So Trivial Can Impact Your Winding Operation

September 20, 2019

A substantial percentage of all products wound into a roll start by applying the material to some form of a tube, or core, to begin the winding process. On the rare occasion, this task can be completed without using a core at all, but the majority use a paper, plastic, or metal tube, with paper being the most commonly used core material. When the roll of material on the core is used up, the core generally gets discarded (think of a roll of paper towels used in your kitchen). These easily disposable items are sometimes viewed as trivial components of the production process, yet they can cause significant pain to those directly involved in the converting process if their quality or physical properties are not suitable for the operation.

Casting Configurations in Film and Sheet Applications

August 20, 2019

Roll Stack, Sheet Stack, Roll Stand, Take-Off System, Casting Machine, these are just a few of the terms that the plastics processing industry uses to describe the equipment immediately downstream of a flat die on a film or sheet extrusion line. Regardless of the term used to describe this device, it’s basically an arrangement of heat transfer rollers designed to cool and shape molten polymer after it has been extruded through a die to form a continuous web of film or sheet. There are many possible arrangements of the rollers, but the most common are horizontal, vertical, inclined, J-stack, and planetary. What are the differences and why would one configuration be used over another?

Obligations of an OEM when Evaluating Legacy Equipment

June 12, 2019

As an OEM of industrial machinery for a wide variety of plastics processing, web handling, and slitting applications, we are often put in a difficult position of responding to requests from customers for upgrades to legacy machines while navigating a minefield of product liability concerns.  This can be frustrating for customers who view the scope of their request as being a “simple” or “minor” upgrade or modification, whereas from the OEM’s viewpoint, the scope of the project, once fully assessed, typically becomes much broader.  When a customer then receives a proposal with costs well beyond what they deem reasonable for the scope of work they are envisioning or are surprised by a refusal from the OEM to even provide a proposal, it can lead to the misperception of the OEM not wanting to work with a customer.  Most of the time, that simply isn’t the case. 

Safety Starts at the Front of the Line

February 12, 2019

Secondary manufacturing and converting operations, such as printing, extrusion laminating, or slitting and rewinding, start by unwinding material from a roll into the downstream process.

Dealing with Breaker Plate Contamination

November 28, 2018

Continuous-belt screen changers are an economical and efficient method of filtering out contaminants in thermoplastic material due to their ability to provide constant melt extrusion pressure to downstream processes over long periods of time. The absence of process interruptions needed to change screen packs in other types of filtration translates into increased production and decreased scrap, bringing maximum efficiency to your extrusion operation. However, if you notice that the pressure drop in your continuous belt screen changer is gradually increasing over time, despite regularly advancing the screen at recommended intervals, you may have a flow restriction from the gradual buildup of contaminants on breaker plate surfaces.

Development of Safety Standards for Film and Sheet Winding Machinery

November 1, 2018

As a manufacturer of machinery for the plastics industry, one of our main concerns when designing, engineering, and building these machines is to always keep safety in mind. Operating machinery can always carry the risk of injury. Workers can be struck by moving parts, trapped between rollers, belts, and pulleys, and cut or punctured by sharp edges. That’s why safety standardization efforts are developed to define, for example, the type of guarding, fencing, or torque limitation. 

Advantages of a Linearly-acting Lay-on Roller

August 15, 2017

In two previous articles, lay-on rollers were discussed. From the evolution of the lay-on roller to the advantages of the more modern linearly-acting lay-on roller and minimum gap configurations to improve winding and web handling performance. Now the discussion will focus on the advantages of having predictable web tension and lay-on nip controls within this type of lay-on roller system.

Linearly-acting Lay-on Roller

July 26, 2017

Over time lay-on roller technology evolved from simple pivoting support arms, to pneumatically loaded, and then the individual lay-on roller system was introduced. However, these individual lay-on rollers added complexity and room for error due to the difficulty of not knowing how much lay-on nip force to apply. Thus, linearly-acting lay-on roller systems were developed to provide better nip force control.

Evolution of the Lay-on Roller

July 17, 2017

Today’s web converters are challenged with production requirements that are becoming increasingly difficult to satisfy with the technology of their older slitter rewinder equipment.Roll quality standards are harder to achieve as materials being processed are thinner, have lower modulus and have either very high or very low coefficients of friction, or when production speeds and finished roll sizes continue to increase. One area where we have seen gains being made is the development of improved lay-on roller systems that help address these process challenges.
