Abstract
Method for constructing a press knife for cutting out sheet material such as leather, wherein machine instructions are generated containing data relating to a desired configuration of the press knife for cutting out a particular profile, the machine instructions are supplied to a bending device (36, 38, 40) and to a strip material feed device (62), the feed device supplies the strip material to the bending device so the bends are introduced into the strip material in accordance with the machine instructions, the formed strip material then being cut off from the stock and assembled and fixed to form the desired knife configuration, preferably being fixed around a support plate which is produced by a forming device (30) fed with machine instructions derived from the same source (12) as those controlling the bending and feeding devices.
