Abstract: Amultiple longitudinal traversing shed weaving apparatus comprises a weaving rotor having beating elements for the laid or inserted weft threads and shed-retaining elements which retain the warp threads, throughout a predetermined path, in their upper shed position and lower shed position. Each intermediate space between neighboring beating or beat-up elements has operatively associated therewith a respective shed-retaining element which determines the upper shed position or lower shed position and, viewed in the direction of travel of the warp threads, there is arranged forwardly of the weaving rotor a control means for the lateral deflection and selective allocation of the warp threads to a shed-retaining element which determines the upper shed position or lower shed position.
Abstract: A device for maintaining an insertion band against an oscillating insertion band wheel by providing a flexible element which is movable in oscillating fashion in synchronism with the insertion band and rests from the outside against the insertion band under an initial stress.

Abstract: A withdrawing carrier for looms with removal of the filling thread from stationary bobbins, the carrier having a hook and a pivotal clamping tongue. An additional clamping element is provided for augmenting the clamping action exerted by the clamping tongue upon the filling thread.
Abstract: Method of forming profiled reed blades by stamping from a metal strip, in which method the reed blades are processed while the ends thereof are still a part of the metal strip, with a final stamping out of the ends to complete the formation of the reed blades.

Abstract: A weft thread conveying apparatus having at least one pair of weft thread conveying rollers with each roller having two conical shaped peripheral portions inclined to each other and extending upward from the roller edge towards the middle thereof and means for tilting one of the rollers to selectively engage a weft thread positioned between corresponding peripheral portions of the rollers.
Abstract: A method of driving shuttles through sheds formed by warp yarns of a wave-type loom in which a transport edge of the shuttles is lubricated before entrance into the warp yarns, and a wave-shed loom for carrying out the method of driving the shuttles.
Abstract: Winding device for the filling-yarn bobbins of shuttles of a multi-shed loom having a filling station, which device has a yarn guide rotating on a circular path and conducting a filling yarn, as well as first means for the successive movement of the empty bobbins into the plane of the circle defined by the rotation of the yarn guide.
Abstract: A band-gripper loom having band guide rollers supported on a housing surrounding the band wheel to prevent the insertion band from lifting off the band wheel, with each band guide roller supported on the inner race of ball bearings.
Abstract: A shuttle construction for weaving machines, having resin-impregnated fabric cover surrounding the center piece which forms walls of the shuttle that come together and overlap in the region of the tips of the shuttle.
Abstract: A jet loom having straight and recessed reed teeth with the rearmost region of the recesses laying in a plane defined by the front side of the straight reed teeth, with the recesses forming a channel for fluid insertion of weft threads.
Abstract: Device for pile fabric looms for feeding pile warp yarns, having a warp beam, a feed roller for removing the pile warp yarns from the pile warp beam, and a guide roller for the pile warp yarns arranged between the pile warp beam and the shed-forming mechanism.
Abstract: A drive, control, and monitoring device for looms in which there is a drive motor connected to the power line, a flywheel operatively connected with the drive motor, an electromagnetic brake and clutch unit arranged between the flywheel and the crankshaft of the loom, and a means for controlling and monitoring the weaving process.
Abstract: An arrangement for fluid jet insertion of weft threads into the shed of a weaving machine, which arrangement is formed from a main duct having a fluid conveying duct and a transporting duct with their axes forming an obtuse angle with one another, and a thread conveying duct which opens into the main duct with its axis in substantial alignment with the axis of the transporting duct, and the main duct having a narrowed cross-section in the region where the thread conveying duct enters into it.
Abstract: A shed forming device on an undulated shed loom in which heddles are arranged along flexible cables and held by them, and the cables during the operation of the loom carry out an undulantly advancing movement for the production of which drive points spaced apart from each other are provided on each cable.
Abstract: An inserting carrier for looms with removal of a filling yarn from stationary bobbins having a filling yarn clamping tongue which is swingable perpendicular to a central plane of the warp yarn and supported on the bottom surface of the carrier.

Abstract: An extending carrier for looms having a hook with a clamping tongue swingable perpendicular to the plane of the hook and having a control surface on the tongue having a deflection edge positioned on the side surface of the carrier which faces the point of formation of the shed of the loom, the point of the structural part which bears the deflection edge extending into the mouth of the hook.
Abstract: The present invention relates to an undulated shed-type loom for transporting shuttles filled with filling thread through sheds by means of electromagnetic fields acting on the shuttles and having means for beating up the filling threads introduced against the fell of the cloth, the beating-up of the filling threads taking place synchronously with the transportation of the shuttles over the width of the loom.
