ABSTRACT:
The position of the gripper unit in a combing machine is monitored, and when the machine is to be halted its stoppage is controlled such that the machine halts always and only when the gripper unit is at its point of maximum opening or maximum closeness to the grabbing rollers. A position sensor (35) is associated for example with the rocker arm (18) which operates the gripper unit and provides pulses at each rocking movement of the arm (18). When the machine motor (27) is to be halted a braking action is produced by a brake (36) after a predetermined time or after measuring a certain number of pulses from the sensor (35) or on measuring a determined time interval between pulses, so as to effectively halt the machine with the gripper unit open.
