Abstract: A drive system for a machine, in particular a weaving machine, is designed in a manner such that controlled electric power is applied to a rotary electric drive motor (2) as a function of particular angular positions of the motor and such that electrical energy applied to the motor is reduced or interrupted during phases of increasing angular speed of the motor. Phases of increasing angular speed are detected by the drive system to determine phases of increasing angular speed. A method for controlling an electrical motor drive system using a switchable reluctance motor to reduce or interrupt electrical energy supplied to the motor based on motor speed increases as a function of motor angular position is also disclosed.

Abstract: A thread section of a weft thread is held precisely ready for a receiving rapier in a feed rapier on a rapier loom despite the effects of retarding forces. Deflections of the thread section by the head of a receiving gripper are compensated for, whereby the feed rapier is provided with a thread clamp on the side facing the feed device for the weft thread, which releases on tension forces occurring in the thread section and permits a deflection of the thread section.
