Trim Handling Systems

Finding the right trim handling system

We have various innovative solutions available to efficiently and easily convey trim. At Kongskilde Industries we offer cost effective ways for you to handle trim with low maintenance and labour costs, regenerative and exceptionally quiet design, and modern hardware.

What is a trim handling system?

Trim handling systems extract trims from several materials including, but not limited to, paper, plastics, foil, and packaging material. The trim handling process may include, for example, the pneumatic conveying of paper edge trims. We have various innovative solutions available at Kongskilde Industries to suit your needs: providing the means to efficiently collect diverse trim materials and easily transport them from a production line to a collection area.

There has been a definite trend toward selecting vacuum trim conveying systems in industrial functions, due to greater winder speeds, stricter noise control, energy conservation, and the ability to keep different types of waste separate from each other for reselling purposes. Edge trim waste material can be suctioned from production lines, to be downsized during conveying.

Why do materials need to be trimmed to begin with?

Take paper as an example – in order to avoid issues such as press jams, or other mechanical problems, the paper needs to be trimmed prior to printing to ensure that all edges are perfectly straight and aligned. In operations such as binding and finishing, trimming occurs to reduce sheets to the desired trim size.

In some cases, trim can be returned to the manufacturing process, thereby reducing the waste leaving the paper mill. When coated, coloured or otherwise special papers are produced, the trim may be partially or entirely discarded.

What components make up a trim handling system?

Trim handling systems can use various sizes of blower and Venturi. Blowers develop air pressures that proceed through the Venturi to create vacuums at the source, pulling trim into the system.

Further components can be integrated into trim removal systems; the materials can flow through inline cutters to then be collected in a Kongskilde multi-separator RVS unit and released pressureless out of the bottom. System layouts and size can be adjusted in order to evacuate trim from several production machines to a single delivery destination and to fit the spacing demands or limitations of particular premises. Otherwise, it is also possible to have material be directed to various destinations.

What are the benefits of a trim handling system?

The volume of waste can be reduced at a discharge point and cut trim can be conveyed over longer distances when an effective trim handling system is in place. Vacuum trim removal systems produce low levels of noise, compared to traditional options, and they eliminate dust problems along the trim duct route, hence making them preferable for work environments.

Every solution from Kongskilde Industries is a tried and tested way of conveying trim with a multitude of applications. Installing a long-term trim handling system does not necessarily have to mean it cannot also be easily modified to adapt to changes in the production flow.
