Problems solved by technology

[0007] In this respect, the methods and devices mentioned above as prior art for destroying or shredding information carriers have the disadvantage that a sheet with a V-shaped fold area reaches the cutting mechanism forward, with the consequence that the fold is shredded. impermissibly large, mostly doubling grain area
Therefore, the pre-specified shredding level or safety is not achieved

Embodiment Construction

[0045] The symbols used in the figures each have the same meaning, even if they are not expressly mentioned for each figure in the description of the embodiment. Concepts like "left", "right", "upper" or "lower" are referred to only with respect to the illustration in the drawings; other positions can result in actual practical arrangements. It should also be pointed out that the diagrams are not purely technical and therefore shaded and broken lines are partially missing. Relative sizing may also deviate from reality.

[0046] figure 1 The device "V" exemplified in is configured for shredding the sheets 2.1, 2.2...2.n present in the stack 1, preferably sheets of size DIN A4. As can be seen, this device "V" comprises: a support device 3 for the stack 1; a cutting mechanism 4 with two counter-rotating cutting rollers 5.1 and 5.2; a sheet gripping and conveying device 6 , which is configured to individually grab the sheets 2.1, 2.2...2.n from the stack 1 and is configured to ...

Abstract

According to the method according to the invention, a stack of paper is placed onto a support, the sheets are grasped individually from the stack and, whilst realizing a sheet loop, are guided one after another through a through-opening in the support to a cutting system, and are shredded in the cutting system, wherein, when the loops are formed, the sheets are merely deformed elastically and consequently reversibly such that by realizing a free end each sheet loop is opened again before it reaches the cutting system, and is cut up, unfolded, into regular particles over its entire length.

Description

technical field [0001] The invention relates to a method for comminuting sheet-like material, preferably stacked paper. Furthermore, the invention relates to a device for carrying out the method. Background technique [0002] Methods and devices of the above-mentioned type are known, for example, in connection with shredders. Here, the paper is cut into strips by means of a cutting mechanism or shredded into small and smallest particles if a higher degree of destruction is required. Depending on the operating mode, the sheets are either removed from the stack individually starting from the uppermost sheet and fed one by one to the cutting mechanism, or starting from the bottommost sheet of the stack by being drawn into the stack support The opening is pulled through and introduced into the cutting mechanism. In order to obtain a faster passage of a greater number of sheets through the cutting mechanism, the successive sheets may partially overlap. [0003] The invention ...
