Cleaning device for blades of machines cutting stacks of self-adhesive sheets e.g. for postage stamps or message pads, presses wiper carrying anti-adhesion agent against blade

摘要

A pressing section (3), holds the stack during cutting. On its (3) side, facing the blade, there is a wiper (6) carrying an anti-adhesion agent. This contacts the cutting blade. The wiper is formed by a strip (8) of absorbent, elastic material held in a groove (7) of the pressing section. The strip is saturated with anti-adhesion agent. The groove is formed in the lower edge of the pressing beam. The strip is held detachably in the groove, where it projects from the edge of the pressing beam; hence during blade (4) operation, it rests against the blade. The strip is made of self-adhesive, resilient foam material. The anti-adhesion agent is a silicon-based material.
