ABSTRACT:
The apparatus for cutting cushion-like packaging material from a web-like supply of material having at least two layers has a base plate (1), a fixed knife (2) and a movable knife (3), which are arranged above the base plate (1), as well as a drive arrangement for the movable knife. The base plate (1) is connected to a shaft (6) for feeding the packaging material. The drive mechanism is connected drive-wise to the movable knife. A counter-holder (5) with a support surface (22) to support the packaging material during cutting and a means for holding (23) the counter-holder (5) above the fixed knife (2) are provided, the whole being such that the support surface (22) is flush with the cutting edge (17) of the fixed knife. By means of the counter-holder, the cutting is improved in an advantageous manner and paper jams are avoided.
