Most converting applications generate waste materials when they process webs of paper, film, foil, textile or nonwoven materials. There are several choices which must be made to contend with continuous edge trim, die cut piece or matrix waste.

Edge Trim

Venturi type pneumatic trim conveying systems, like Double E Group's FOX TrimAway are modular in nature and are an excellent choice for efficient, reliable and cost-effective edge trim waste handling. These types of edge trim conveying systems employ powerful, energy frugal, regenerative blowers to power a specialized venturi designed for continuous trim or matrix conveyance. Venturis, like FOX TrimAway generate suction to capture waste from converting processes, then pneumatic pressure to convey edge trim and matrix waste short or long distances.

Example of a Pneumatic Conveying system

Things to consider:

Keep intake distance to a minimum. Intake duct is the total amount of duct on the suction side of the venturi. There is far more air flow on the discharge side of the venturi, typically twice the suction side. Short intake distance gets the trim to the most powerful portion of the system in the least amount of space.

Lay-out and Specifications to Consider

Ensure the blower pressure, powering the venturi, is operating at the highest possible pressure. Your system layout should ensure leak free motive connection between the blower and venturi. Keep the number of motive duct bends to a minimum.

Many Blower Sizes from which to Choose

All duct work bends should be long sweeps. Sharp elbow type bends create restriction and stop the easy flow of the edge trims through the system.

Sweeping Bends

Most venturis are adjustable if the system is under powered or overpowered for your application. Always follow manufacturer's instructions for venturi adjustment.

FOX TrimAway Venturi Operating Principle

Most blowers, as supplied with FOX TrimAway systems, can be controlled with variable frequency drives (VFD). Controlling with a VFD can increase efficiency and decrease overall power consumption.

Chopping is optional! Double E Group's FOX TrimAway systems do not require the edge trim be broken up or chopped. FOX TrimAway systems are designed, specifically, to convey continuous edge trim or matrix as a standard feature of the system. However, Double E Group's FOX TrimAway product offers TrimAx trim choppers for applications where pieces are desired (instead of continuous trim) or for applications where extremely long discharge lengths require the conveyance of pieces.
