A drive mechanism for driving a heald frame of a weaving machine, the drive mechanism having a crank rotating about a crank axis, a coupling rod, and a swivel lever having a first arm and a second arm, the coupling rod is linked to the first arm of the swivel lever by a second hinged joint adjustable with respect to the first arm of the swivel lever, wherein in at intended locations of the second hinged joint with respect to the first arm of the swivel lever, the second hinged joint is situated on an arc of an imaginary circle when the swivel lever is in a central position between the upper position and the lower position, wherein the imaginary circle has a radius that is equal to the distance between the first hinged joint and the second hinged joint, and the imaginary circle has a center that coincides with the crank axis.

Drive mechanism for driving a heald frame of a weaving machine

A drive mechanism for driving a heald frame of a weaving machine, the drive mechanism having a sensor device, wherein the sensor device has at least three members having both a target set with one or more targets and a detector set with one or more detectors, wherein one of the detector set and the target set is arranged at the swivel lever and the other one is arranged stationary on the weaving machine, targets of the target set and/or detectors of the detector set have different characteristics for generating a first signal when approaching the measuring position from the upper position or when departing from the measuring position towards the upper position and for generating a second signal when approaching the measuring position from the lower position or when departing from the measuring position towards the lower position, and the second signal differs from the first signal.

Drive mechanism with a sensor device for driving a heald frame of a weaving machine

A drive system for a weaving loom includes a switching wheel () which can be driven by of a main drive motor () and can be axially displaced between at least two switching positions, which, in a first switching position, is in drive connection with two groups of elements to be driven () and, in a second switching position, is disengaged from one of the groups of elements to be driven (). A device () is provided which becomes active as the drive connection with one group is disengaged and which has a tooth element () which engages with a gear wheel () of the group of elements to be driven () and disengaged from the switching wheel ().

Drive for a web machine

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 () 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.

Method for driving a machine and drive for said machine

A drive for a mechanical loom. The drive includes a main drive shaft (,) that is mounted in a machine frame (,) and is driven by a drive motor (,) which is disposed coaxially to the main drive shaft (,) and directly connected thereto. The main drive shaft (,) is preferably designed as a motor shaft for the drive motor (,).

Drive for a mechanical loom

A gear (1) for driving a rapier of a loom and composed of a separately manufactured synthetic base body (3, 5) to which a wear-resistant band (9) forming the outside teeth (2) of the gear is bonded by an adhesive (10).

Gear for driving a rapier of a loom

A loom drive comprising a drive motor (1) connected by a gear unit to first driven components (20) and to second driven components (23), a switching gear (15) being mounted inside the gear unit and being displaceable into different switch positions in such manner that in one switch position the main drive motor (1) drives the first and second driven components (20, 23) and that in another switch position the drive connection to the first or second driven components (20, 23) is interrupted.
