Abstract
A device (1) and a method are provided for shedding with a warp thread (5). The device has a lifter (7) that is connected to a resilient spring element (9) and to the warp thread (5). The device also has a controllable actuator (11). The spring element (9) is non-rotatably clamped at both spring element ends in mountings (13, 15). The spring element (9) is compressed axially at one side by the actuator (11), forcing the spring element (9) to flex and forcing the lifter (7) to be oscillated by alternating flexural deformations of the spring element (9).
Claims47
An actuating device for a mobile element, shedding device with a warp thread, the actuating device comprising:
- a spring element with spring ends;
- mountings clamping the spring ends;
- a lifter connected to the spring element, the spring element being capable of buckling and bending and being connectable to the mobile element;
- and
- an actuator, wherein the actuator forces the spring element to buckle and the lifter is moved in an oscillating manner by alternating buckling deformations of the spring element, wherein the spring element is compressed by the actuator on one side as well as axially.

A shedding machine comprising:
- a plurality of devices for forming sheds, including double-stroke open sheds, with warp threads of a power loom, each of the devices comprising:
- a spring element with spring ends;
- mountings clamping the spring ends;
- a lifter connected to the spring element, the spring element being capable of buckling and bending and being connectable to the mobile element;
- and
- an actuator, wherein the actuator forces the spring element to buckle and the lifter is moved in an oscillating manner by alternating buckling deformations of the spring element, wherein the spring element is compressed by the actuator on one side as well as axially.
(canceled)
A method for shedding with a mobile element, especially with a warp thread, by means of an actuating device, which comprises a lifter that is connected to a spring element capable of buckling and bending and can be connected to the mobile element and a controllable actuator, the method comprising the steps of forcing, with the actuator, the spring element to buckle, and the lifter is caused to perform oscillating motions by alternating buckling deformations of the spring element;
- clamping the spring element nonrotatably in mountings at both ends;
- and
- compressing the clamped spring by the actuator on one side as well as axially.
