ABSTRACT:
A simplified, relatively low cost web-cutting cylinder and assembly adapted to be mounted on a web collator and having a vacuum-type, through-the-cylinder slug removal feature is provided which permits easy, clean, high-speed removal of successively cut web slugs produced when standard English-sized equipment is used to produce metric-sized business forms or the like. The cutting cylinder is adapted to be mounted adjacent a conventional, unmodified anvil cylinder and preferably includes an inwardly and axially extending, tapered bottom, slug-receiving slot or groove and a pair of slug-cutting peripheral knives mounted on opposite sides of the slot; a vacuum slug-removal system is coupled in communication with the slot for removing cut slugs without the necessity of any moving parts which can limit collator output and substantially increase equipment costs. Additionally, application of a vacuum pulling force on the slugs as they are cut significantly enhances high-speed slug removal and effectively solves the problem of incomplete cutting and hang-up of web fibers on the cutting blades.
