A method of converting a cutting machine for the preferably three-sided cutting of a sheet stack

摘要

In the case of three knife vending machine (10) for the three-sided cutting of a pressure sheet stack (11) is required for each change of format conversion. For this purpose, the cutting plate (15), and the press ram (16) are replaced.It is provided according to the invention, the replacement of the cutting plate (15) and of the press ram (16) to carry out automatically, and indeed with the aid of a positioning device for positioning of the pressure to be cut sheet stack (11) under the press ram (16). It is thus the automatic changeover of the three knife vending machine (10) for a change of format without any noticeable change in the three knife vending machine (10) necessary. Only the control of the positioning device must be changed and extended. The positioning device (21) is automatically ensured that the new press ram (16) and the new cutting plate (15) are positioned exactly. In particular, the positioning of the die (19) under the conveyor plate (18) with the requisite high accuracy by means of the positioning device can be automatically, and indeed with a greater accuracy, would be possible as the manually.
