What are trim removal systems?

Trim removal systems collect and convey (pneumatically) film and foil off cuts generated by several major production processes. They help manufacturers save money, optimise productivity, increase recycling and improve safety.

How does the process work?

The trim is collected using a suction process, and conveyed through a purpose-built pipework system. The pipework transports the trim using a high speed air stream. Blowers are used to drive the air stream and deliver the trim to compactors, horizontal balers or large mobile storage containers. The trim is then prepared for disposal or recycling. These systems are carefully integrated into the factory to maximise operation and maintainability.

What types of systems are there?

Two main types of systems are used to collect and pneumatically convey trim to a waste collection point.

Venturi trim removal systems

This type of trim removal system uses a venturi component to transport a continuous ribbon of trim.

Cutter trim removal systems

The other type of trim removal system uses a cutter to convert the trim into high density, low volume confetti while transporting it.

Where are these systems used and for what?

Trim removal systems are mainly used in machinery for converting (rewinders and slitters), film and foil (cast lines) production and paper manufacturing. They are used in the industrial production of the following products:

  • Aluminium foil and packaging
  • Carpets and textiles
  • Corrugated cardboard packaging
  • Plastic foil and packaging
  • Labels and self-adhesives
  • Toilet tissue and kitchen towels
  • Web and continuous printing

Venturis vs cutters trim removal system

There are several factors to consider when selecting the type of trim removal system that will best suit your needs. A venturi trim removal system is generally considered the most economical, however, the best long-term return can come from using a cutter trim removal system. We have listed below the major factors that will help you choose what is the best type for your situation.

Venturis cost less to install

Venturi trim removal systems come at a much lower installed cost compared to cutters. They are ideal for companies that want to save on labor and maintenance costs but do not have enough capital to invest in a cutter system.

Cutters cost less to operate

Cutters cost substantially more to install but provide greater return on investment over time. These systems require fewer loads for disposal or recycling, as their waste volume is greatly reduced. Cutters also use much less energy than venturis and operate at lower cost.

Venturis are easier to install

Venturis have fewer components, are simpler, and take less time to install. Cutters require more consideration in design and greater effort to install. A venturi trim handling solution can be temporarily installed quickly, while a cutter is designed and installed.

Venturis keep trim intact

Venturis simply transport the trim to the waste collection point as a continuous ribbon. They do not process the trim in any way. Cutters process the trim to confetti.

Both work well in high-speed production

Both venturi and cutter trim removal systems are great for continuous and high-speed trim production lines.

Cutters work best over long distances and several bends

Cutters are best when you need to convey trim over long distances or through several bends in the pipework; long distances with turning and twisting pipework are no problem. Venturis are not effective when transporting trim over long distances or with pipework that has three or more bends.

Cutters work best with multiple production lines

Venturis require much more energy to transport trim than cutters. More production lines will make the system energy-inefficient. Venturis also require a large footprint on the factory floor. Cutters are energy-efficient and centralised to service several production lines, requiring a relatively small factory footprint.

Cutters are best to bale trim waste

Bale waste from a venturi is inefficient compared to cutters. As the trim is in a continuous ribbon rather than confetti, the bales are looser and bulkier. Cutters process trim into small pieces that are easily compacted into low volume, high density bales.
