Abstract
An electronically controlled web-slitter includes dual electric motors whose functions may be controlled by an electronic controller accessed either on the chassis of the web-slitter or by way of a computer coupled to the electronic controller. Vertical and side-shift blade set-up and functions are accurately controlled. The device includes a dovetail fitting for providing structural connection of parts, and a follower engaged with said first motor for translating rotational movement into vertical motion, and multiple sensors for sensing and controlling motor positions within the device.
