longitudinal perforating machine / paper
Length perforation modules are primarily integrated into slitting machines to separate materials. In some cases special perforation shapes, such as wavy perforation lines, are used to create security features. The perforation knife holders pneumatically engage or disengage the perforation wheels. An adjustment feature for the cutting gap between the anvil cylinder and the knives is integrated in the knife holder providing an individual setting for each knife. This outstanding feature provides the advantage to use new and reground perforating wheels at the same time. The perforation wheels are suitable for converting speeds up to 300 m/min. The perforation wheels are driven by the web/anvil cylinder which is mainly driven by a servo motor.
Besides the modules and the knife holders, Schobertechnologies supplies length perforation wheels. Most of the standard dimensions are on stock. Special dimensions can be supplied on short notice.
