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