Control device to implement grinding process for a knife shaft

摘要

The present invention relates to a control device (5) to grind a knife shaft (40,50) used in a machine intended for cutting sheets of materials into strips, for example sheets of paper, plastic, plates of photosensitive film or any other material having the form of thin sheets.;The control device (5) according to the invention enables the grinding of the knives (20,30) of knife shafts (40,50) of a slitter by checking and controlling the drift of the dimensional differences of position of the knives (20,30) on the knife shaft (40,50) and by controlling the variability of the pitches between the knives (20,30). This with the goal of obtaining the precision and the quality of cutting required for cut photographic film strips.;This device especially finds its principal application in the photographic industry, in particular on grinding machines for the knives (20,30) of knife shafts (40,50) equipping the film slitters.
