ABSTRACT:
A device for improving the control of the correction movement of the copying roller of a machine for roughening a margin of a tightened shoe upper comprises a holder of the copying roller which is slidably seated in the basic body of a treating head and connected to a motion gear controlled by means of electric circuits according to a selected program. The correction movement of the holder with the copying roller is controlled by electric circuits, which switches, according to the preselection of code switches, the selected combination of electromagnetic valves of distributors of respective pressure cylinders. The sequence of switching of selected combinations of the electromagnetic valves is determined by switching one of two selecting switches, which control the working cycle of the roughening of the lasting margin of the left shoe or the right one. The whole value of the correction movement of the holder results from the sum of movements of pistons of pressure cylinders. The invention may be used in machines for roughening a lasting margin of a tightened shoe upper.
