Abstract: The admission of pressurized fluid into the weft insertion nozzle of a loom is detected by an electrical signal generating means arranged in the nozzle in communication with the fluid delivery passage through the nozzle, the generating means generating a signal indicative of such fluid admission and applying the same to a conductor extending to an exterior point for use in monitoring the proper operation of the loom. Preferably, the signal generating means is fluid pressure responsive, such as a piezoelectric crystal exposed to the fluid pressure in the nozzle passage.

Abstract: A selvedge cutting device for a weaving machine or loom serves to cut the selvedge from the fundamental weave or foundation fabric prior to winding-up the same and contains a scissor structure composed of two mutually contacting scissor blades. The one scissor blade is arranged at a mounting structure, such as a stationary ball pin or bowl gudgeon for carrying out swinging or pendulum movements and in relation to which mounting structure the other scissor blade is displaceable in its lengthwise extent. Both of the scissor blades form, at the region of their cutting edges, guide surfaces for the self-guiding of the scissor structure in a cutting lane or alley at the fabric. At the displaceable scissor blade there engages a drive which imparts to such scissor blade an up-and-down movement and does not hinder the pendulum or swinging movements of the scissor structure. In this manner there is provided a simple, functionally reliable selvedge cutting device possessing a high cutting capacity or output.

Abstract: A thread clamp for textile yarns or the like comprises two clamping jaw supports which can be moved relatively towards and away from one another. Each of the clamping jaw supports carries a respective clamping jaw. The clamping jaw of one of the clamping jaw supports is constructed as a clamping hood which is seated upon a substantially block-shaped intermediate layer formed of a rubber-elastic or elastomeric material. The intermediate layer has a portion thereof seated in a form-locking fashion in a recess provided at a base plate at said one clamping jaw support. These measures enable particularly realizing an optimum clamping action due to the oscillation-dampening properties of the intermediate layer supporting the clamping surface.

Abstract: An intermittently-operating strand delivery system having:(1) a nozzle passageway through which the strand is guided;(2) a supply for pressurized medium;(3) conduit means connecting between said nozzle passageway and said supply including a pressure-operated on-off flow valve; and(4) separate servo valve units for independently applying and releasing control pressure, respectively to and from the pressure-operated flow valve to move the cam between alternately open and closed positions to admit medium from the supply to the nozzle passageway for a controlled interval and thereby permit a pulse of medium to pass through the nozzle passageway and project a length of the weft strand therefrom. The servo units can take the form of separate solenoids or rotary spool valves. The opening of the pressure-operated valve preferably incorporates an avalanching effect to accelerate its opening action.
