Abstract
Abstract An apparatus for moving thread guide devices of textile machines wherein two traction elements are provided which move to-and-fro in a translatory fashion in opposition to one another between two terminal positions, these traction elements being coupled with one another by a connection element and via the latter acting upon the thread guide devices. A stationary retaining or holding element is associated with each traction element and each such retaining element selectively retains the associated traction element in one terminal position in accordance with a control program.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
An apparatus for moving a single thread guide device of textile machines, said apparatus comprising two traction elements, means for moving said two traction elements to-and-fro in translatory fashion in opposition to one another between two terminal positions, connection means inter-connecting said two traction elements with one another and acting upon the single thread guide device, a stationary retaining element operatively associated with each traction element for selectively retaining the associated traction element in one terminal position as a function of a control program to selectively vary the position of the single thread guide device.
Claim 2
Independent Claim
95 words
An apparatus for moving a single thread guide device of textile machines, said apparatus comprising two traction elements, means for moving said two traction elements to-and-fro in translatory fashion in opposition to one another between two terminal positions, connection means inter-connecting said two traction elements with one another and acting upon the single thread guide device, a stationary retaining element operatively associated with each traction element for selectively retaining the associated traction element in one terminal position as a function of a control program to selectively vary the position of the single thread guide device.
Claim 3
Dependent Claim
165 words
The apparatus as defined in claim 1, further including a roller, said connection element being guided about said roller, a spring element, means operatively connecting said roller with said thread guide device, means connecting said spring element to said thread guide device for resiliently resisting movement thereof by said roller with said roller being displaceable away from said spring by said connecting element; said traction elements each being of substantially rod-shaped configuration and possessing a hook member, said means for moving said traction elements including guide mechanisms cooperative with said rod-shaped traction elements, and drive means for driving said guide mechanisms between two positions to-and-fro in opposed relationship and generally in the effective direction of said spring element, each retaining element having a retaining hook member rotatable about a stationary shaft, means for rotating each retaining hook member between a release position and an effectual position, and each retaining hook member in its effectual position engaging with the hook member of the associated traction element.
Claim 4
Dependent Claim
31 words
The apparatus as defined in claim 2, wherein each traction element is displaceably guided through the associated guide mechanism and possesses a stop element which cooperates with the associated guide mechanism.
Claim 5
Dependent Claim
54 words
The apparatus as defined in claim 2, said means for rotating each retaining hook member including an electromagnet for retaining each associated retaining hook member in one of its said positions, and a spring means working in opposition to said electromagnet for retaining each retaining hook member in the other of its said positions.
Claim 6
Dependent Claim
20 words
The apparatus as defined in claim 4, wherein each retaining hook member defines a magnetic armature of the associated electromagnet.
Claim 7
Dependent Claim
49 words
The apparatus as defined in claim 5, wherein each retaining hook member is coupled with a return mechanism which, as a function of the control program, serves to bring the associated retaining hook member, against the action of the spring means, so as to bear at the associated electromagnet.
Claim 8
Dependent Claim
35 words
The apparatus as defined in claim 2, wherein the retaining hook members are coupled with a preliminary needle arrangement which brings about rotation of the retaining hook members from their one into their other position.
