Knifeholders Slitting Systems
We offer pneumatic knifeholders designed and developed after the newest standards. In order to cut a broad spectrum of materials, we have two types available.
The WISTEC Knifeholder 20-100 is appropriate for shear cuts of web materials. The minimum cut width amounts to 20 mm. Here you can find the main and connection dimensions.
The WISTEC Knifeholder 20-100 is an unusually durable and highly loadable mechanical component. It is torsionally stabile and traces faithfully, characterized by the guidance of double ball-bearings.
It possesses an integrated pneumatic control which ensures, as technical innovation, that the horizontal movement can only take place if the cutter head achieved its lower end position. Complex compressed air adjustment, a second compresser air port for the horizontal movement, or damaged knives by premature contact with the bottomknife belong in the past. The WISTEC Knifeholder 20-100 represents a flexible construction kit system. It can be adapted easily on existing guide rails. The knives can also deflect from used standards (Ø100 x Ø70 x 1.2 mm) without any problem.The WISTEC holder possesses a defined cutting angle. Nevertheless, you can easily use the second edge of the bottomknife by turning the cutter head around 180°.

The WISTEC Knifeholder 40-150 is designed for shear cuts, as well.
A minimum cut width of 40 mm and a stabile mechanical structure permit advanced and heavy applications like cutting papers, foils, and laminates of up to 150....200 g/m², and foil thickness of approx 1.5 mm.
Here you can find the main and connection dimensions.The constructional design assures that the knifeholder can be adapted to all known systems of guide rails. An upgrade to already existing products does not present a problem. The knifeholder is suitable for operations in automatic positioning systems. The possibility exists to adapt the product to the standard (Ø150 x Ø80 x 2.5) deviating dimensions of circle knifes. To reach higher speeds, there is a special modification kit for plate knife Ø 200 mm. The WISTEC holder possesses a defined cutting angle. Nevertheless, you can easily use the second edge of the bottomknife by turning the cutter head around 180°.

To build a cutting system for lengthwise cutting of web materials, it is necessary to drive on the lower knifes. Primarily, those are positioned on the pneumatic knife expanding shaft, which allows a fast setting of the cut width.

The cutting width setting, which means the positioning of the bottomknifes and movement of the knifeholders, can be completely automated by using a computer-aided positioning system.
