Featured Tech tip: Trim removal systems come in all shapes and sizes.


Tech tip: Trim removal systems come in all shapes and sizes.

Here are some guidelines to help you understand how trim removal systems are designed for specific applications.

  1. Air speed. As a general rule of thumb air speed should be AT LEAST double the speed of your web in feet per minute. Again, this is really a very general rule of thumb; some trim applications may require air speed faster than 2X.
  2. Air volume must be calculated through the system from the pickup point to the discharge area. There will be pressure losses through any length of duct. It is important to calculate volume, speed and pressure of the air at several points through duct work to understand how large the system needs to be and how the system must be designed.
  3. Use sweeps for all bends. Sharp elbows GREATLY restrict air flow and cause large pressure drops. Trim has difficulty making turns through sharp elbows.
  4. Use rigid duct for long lengths. Most trim removal systems are available with semi-rigid steel flexible duct, which is fine for short runs and is very practical for tight areas in your machine. However, systems should be designed with rigid duct for long lengths because rigid duct does not leak, air friction is much less than with flexible duct and it will stay straight over long distances.
  5. All systems should be designed with minimal air leakage. This may sound obvious. However, air leakage is sometimes over-looked as a design consideration.
Ultimately, if your trim removal system is designed properly, it should remove your trim reliably. Your trim removal system should not hamper your production in any way.
