Abstract

The copying system controls tool movements in two per pendicular directions of which one is related to template profiles. A slave loop includes an error signal-emitting sensor following the templates, the sensor (30) being connected to an amplifier controlled by a motor. The amplifier (36) comprises a comparator whose inputs (42, 43) receive the error signal and are connected to an adjustable reference signal source (44) respectively, and may be electronic with the sensor utilising electric voltage to form error signals. The reference signal may be formed by constant adjustable voltages produced by dividers (45a to 45d) with automatic circuit breaking (46a 46d) commutation and each having individually adjustable reference voltages.
