The ELCUT web cutter trims movingfabric webs at the edges exactly to theusable width required.The proven shearing cut principle withpowered top and bottom blades assuresprecision cutting.
In the case of frequently changing proces-sing speeds especially, it is an advantagewhen the cutting speed may be adjustedinfinitely to match. Besides a presetspeed, the operator may select one of arange of variable cutting speeds.
Crucial to precision cutting is the correctcutting force. For this reason, the operatorhas a choice of three different blade setsto suit specific fabrics.

FunctionThe top and bottom blade shaft, mountedat one side on bearings, is driven by athree-phase a.c. motor via a multi-stepspur gearing. Various gear ratios permitthe selection of different cutting speeds.The cutting speed may also be adjustedto the processing speed with frequency-controlled three-phase a.c. actuators.
Implementation areaThe main area of implementation is pro-cessing machines for paper, film, fabricsand non-wovens. In the majority of cases,mounting is after the final processingstage prior to winding.
ApplicationThe web cutter is suitable for horizontaland vertical web travel. An optimum cut-ting position is when the web cutter is til-ted at an angle of 15°. A maximum usablewidth may be achieved if a web guider ismounted in front of the cutting station.
PositioningA range of support beams is available formanual or motor-driven positioning.
