ELECTRONIC CONTROLLING EQUIPMENT FOR DRIVING SYSTEMS WITH ELECTROMAGNETIC COUPLINGS FOR INDUSTRIAL SEWING AND/OR OVERCASTING MACHINES

摘要

An electronic controlling equipment of the driving systems with electromagnetic couplings destined to equip industrial sewing and/or overcasting machines. The electronic controlling equipment performs the continuous speed adjustment, stopping at the fixed, preselected point and controls for additional operations at the sewing and/or overcasting machines: the lifting of the footlet, the drive of the scissors and the thread loosening by means of a driving control, of an analogical scheme for the speed adjustment by chopping, of a braking scheme and stopping at fixed point controlled by a speed and position transducer, corresponding to a logical scheme of interconditioning and interblockings.
