Process for vacuum removal of particles formed by continuous slitting of web material, such as on rotary printing machines

摘要

A process for removing particles from one or more material webs (5), continuously moving in a direction (6), particularly at disc knife slitting stations on rotary printing machines., where suction zones are created at the slitting points. Preferably the suction points are also provided with fixed brushes (17) which may be set at variable inclinations to the web, by an adjuster arrangement (13,14,18,19).
