Solution Overview

The precision trim cutter is a compact and versatile precision cutting unit used with Impact’s label matrix extraction systems, among others.

The trim cutter unit is designed to offer precision cutting of a wide range of continuous materials. It enables continuous web manufacturers, slitters and converters to remove edge trim from production. It can cut cleanly through very thick materials like carpet edge trim. At the other end of the scale it can deal with extremely tough plastic film, foils, fabrics, filaments and non-woven materials down to as little as 12μm thin.

Two base models are available in the range. A model 78 series unit is ideally suited to materials being conveyed in ductwork up to 150mm in diameter. The model 811 series cutter is most suitable for larger volumes and heavier materials.

The advantages of the 78 and 811 series cutter are explained below:

Rotating fly knives are cylindrically ground in housing to ensure uniform clearance across the complete width of the bed knife. Proprietary milling process matches fly knives to rotor notches for secure, positive location and retention. Available in standard AISI-D2 tool steel or in optional tungsten carbide.

Cutter Exchange Service
At Impact, we realise the importance of keeping your cutter running efficiently.  From time to time, depending on the application, you will need to have the knives re-sharpened and set or the complete cutter exchanged.

Worn or damaged knives must always be re-sharpened before adjusting cutting clearances.

The re-sharpening and re-setting of the knives is a very precise procedure with clearances being set as little as 0.00025” (6.35µ) and must only be carried out by a skilled engineer who is familiar with the 78/811 Series and who has been suitably trained in the use of surface and cylindrical grinding. The knives can not be precision set to the required accuracy unless they are fitted into the cutter unit, they cannot be removed, sharpened and then re-fitted. With this in mind we strongly recommend you contact us and we will arrange for the necessary work to be carried out.

Cutter exchange:
Contact us when your knives are ready to be re-sharpened and set. We will ask for a purchase order number and then arrange for a re-furbished, serviced, replica cutter to be despatched to you within 1 or 2 days (dependent on availability). When you receive the cutter it should be swapped with the worn cutter, this ensures that you will only suffer minutes of downtime and maximum operating efficiency will be restored. The worn cutter must then be returned to us within 14 days.
