An apparatus for tensioning warp threads in a weaving machine having a rotatably mounted carrier beam (,) which exerts strain on a tensioning roll (,) acting on the warp threads (,). A pre-stressed torsion spring (,) is arranged inside the carrier beam (,) and via its torque, presses the tensioning roll (,) against the warp threads (,). The apparatus can sense the torsional moments of the torsion spring (,).

A device for affixing a shaft drive element to a loom warp beam shaft includes a clamping element having teeth, teeth at one end of the drive shaft and teeth on the drive element, and a displacement mechanism for sliding the clamping element and drive element on the drive shaft such that the clamping element teeth and the drive element teeth engage the drive shaft teeth. Upon sliding the drive and clamping elements over the drive shaft, the clamping and drive element teeth and the shaft teeth are mutually rotated to cause oppositely facing flanks on the drive and clamping element teeth to be pressed against corresponding flanks on the drive shaft teeth and thereby prevent relative rotation.

An apparatus for adjustably affixing a support bracket to a part of a machine frame includes an adjustment screw to adjust the height of the support bracket on the frame and a pair of oppositely movable clamp elements having oblique surfaces for wedging the support bracket in place following adjustment. Wedging is accomplished by turning a setting screw to move the clamp elements in mutually opposite directions. The setting screw is parallel to the adjustment screw, allowing equal access to both the adjustment and setting screws.

A device for attaching an element in a frame includes a seating, a supply path via which the element to be attached is brought to the seating, and a pivotable member. In a first position of the pivotable member, a first end thereof is situated in the supply path. In a second position, the first end is situated outside the supply path and a second end of the pivotable member to move the pivotable member between its first and second positions. The first position of the pivotable element is an overcenter position in which the relative positions of the pivotable member's pivot point, the seated element, and the point of contact between the seated element and the first end of the pivotable member are arranged to retain the seated element in place within the seating. In the second position of the pivotable member, the transport device moves the element via the supply path into and out of position in the seating.

Supporting device for the back rest in a weaving machine, characterized in that it mainly consists of a first element (13) which can move in relation to a frame (14) and a second element (15) upon which the back rest (3) has been mounted, whereby this second element (15) is attached to the first element (13) in a hingeable manner on the one hand, and is being supported by elastic element (17) on the other hand.

Supporting device for the back rest in a weaving machine

Supporting mechanism for the back rest in a waving machine, consisting of at least two supports which support the back rest at its respective ends, characterized in that each support (11) essentially consists of at least two leaf springs (12, 13) mounted next to one another and attached at one of their ends (14, 15) to one another and to the weaving machine, and which at their opposite ends (16, 17) are also connected with one another in order to support the back rest (3).
