Abstract: An intermediate support in engagement with heddle carrying rods of a weaving heddle frame includes a body member having end loops at opposite ends for engagement with the rods, at least the body being of vibration absorbing material, and the end loops engaging the rods but without being fixedly secured thereto. The end loops are spaced apart for maintaining a constant spacing of the rods, and the intermediate support is capable of being laterally shifted along the rods to accommodate the positioning of the weaving heddles therealong.

Abstract: A warp stop motion apparatus includes individual disengageable coupling and control elements which have fork-like ends that are capable of surrounding the lateral sides of drive pins extending outwardly from the opposite sides of the end portions of the respective inner movable serrated bars which slidingly extend into a housing part that is oscillated back and forth by an individual electrical motor. Oscillation of the housing part causes the inner serrated bars to oscillate in their longitudinal direction with respect to outer stationary serrated bars in which they are positioned.

Abstract: A warp stop motion device of a weaving machine has upper and lower supports respectively for contact bars and guide bars lying in transversely spaced vertical planes with vertically extending legs thereon having adjustment and locking means to facilitate a clamped vertical adjustment between the upper and lower supports. The lower supports are cantilevered at one end to a longitudinally extending beam serving as a warp end carrying support, and the upper supports are cantilevered at one end to the one end of the lower supports. Thus, the opposite ends of the upper and lower supports are free and unsupported for the reception of the guide bars from such ends during assembly.

Abstract: A weaving reed comprises a plurality of flat reed dents stacked side-by-side in a reed channel or container, each reed dent having opposed end sections terminating in side edges, one of such end sections of each reed dent having an outer edge thereof provided with an identification notch spaced from the side edge at that end section a distance corresponding to the thickness of a given reed dent, such that stacked reed dents of like thickness will have aligned identification notches, and stacked reed dents of unlike thickness will have staggered identification notches relative to the aligned notches. Reed dents of different thicknesses are therefore immediately distinguished and can be easily sorted out.

Abstract: A heddle frame stave for heddle frames includes a light metal hollow construction having, at least on one side wall, and preferably on opposing side walls, a flat groove-shaped recess. A flat steel strip is adhesively secured in the recess, the strip having a thickness of less than half the side wall thickness and covering preferably at least 60% of the surface of the side wall of the hollow stave. Vibration dampening of the heddle frame stave is thereby achieved, so that the sound produced due to vibrations and the noise development associated therewith, will be reduced considerably especially for fast running weaving machines.

Abstract: A weaving heddle frame has frame staves of lightweight construction with each stave having at least one heddle carrying rod located on one side thereof for taking up heddles with laterally open end loops. The rod has a longitudinal edge facing the frame stave and has an outwardly facing front side. A cover of a hardness which exceeds that of the rod engages the edge and side thereof and is interconnected with the rod for improving upon the resistance thereof against wear caused by the heddles.

Abstract: A weaving heddle comprises a strip of material of constant cross-section throughout its entire length, and has open end loops of plastic material molded in place on oposed end sections of the strip. A central section of the strip between the end sections has a centrally located thread eye. The end loops have bearing surfaces for engaging heddle carrying rods of a heddle frame, such surfaces lying along a common axis. This central section of the strip is bent and offset from such axis in the same lateral direction in which the end loops extend from their end sections.Such a bent heddle may be utilized with an unbent heddle so as to form a heddle pair having two thread eyes. This other heddle comprises a straight strip of material of constant cross-section throughout its entire length, with open end loops, corresponding in shape and size to the end loops on the bent heddle, being attached to opposed end sections.

Abstract: The connecting part for electrical warp stop motions on weaving machines has two rectangular housing shells (2,3) pressed against each other at their open sides by means of a threaded pin (10) screwed into the first housing shell (2). The screw-head of the threaded pin is in the shape of a knob (11) and presses against the second housing shell (3). In the longitudinal sides (4,6) of both housing shells (2,3) are supporting slots (9) at equal distances to take up the contact bars. On the interior base (12,15) of each housing shell (2,3) is a strip (13,16) of elastic material and on each strip a contact foil (14,17) for conducting electricity to all the contact bars, the narrow edges of which have perfect contact with the contact foils, even at varying height resulting from deviations in manufacture, due to the elastic material under them.

Abstract: A weaving heddle includes an elongated heddle shaft having U-hook shaped end loops at opposite ends for holding the heddle on opposed heddle carrying rods of a heddle frame. The loops include shanks for overlapping with the rods, and the loops have inner support surfaces spaced a predetermined distance apart and extending transversely of the shaft for engagement with the rods. One of such support surfaces is resiliently biased toward the other of such surfaces for accommodating any increase in such predetermined distance.

Abstract: The heddles of a weaving machine have vibration absorbing material on the end loops thereof which normally contact edges of metal rods mounted on a heddle frame for oscillating movement, the heddles effecting a lifting movement relative to the rods upon oscillation thereof. Metal-to-metal contact between the end loops and the rods is therefore avoided so as to reduce noise during operation of the machine and so as to avoid corrosion of the heddles and the rods.

Abstract: The heddle carrying rods are provided with open ended axially extending slots in each end. Connectors are provided having longitudinal edges complementary to the longitudinal edges of the slots to define a tongue and groove connection. One end of a connector may be slidably connected in the slot with the opposite end having a locking configuration to retain the connector in the slot for preventing the removal of heddles from the rod, a bevelled end piece configuration to facilitate the insertion of heddles on the rod or an identical symmetrical configuration for insertion into a slot in another rod to facilitate transfer of heddles from one rod to another.

Abstract: A heddle frame is provided with a frame stave having a heddle carrying rod connected to and disposed below the stave in spaced parallel relation. The ends of the frame stave are connected to lateral supports in such a manner that the lateral supports will be offset from the ends of said heddle carrying rod to allow for the placing on and removal of heddles on said rod without interfering with the lateral supports. Pivoted locking levers ae provided adjacent each end of the rod to selectively allow the placing on and removal of heddles on said rod.

Abstract: The lateral support of the heddle frame is provided with a projection which is received in a complementary recess in the end of the frame stave. The upper surface of the projection is provided with a bevelled surface. A screw extends diagonally into the recess from the outer edge of the frame stave adjacent the lateral support with the central axis of the screw disposed perpendicular to the bevelled surface to prevent the withdrawal of the projection from the recess when the end of the screw is disposed in engagement with the bevelled surface.

Abstract: A wear resistant leno heddle is disclosed which has a doup and two lifting heddles. The lifting heddles are formed in one piece by moulding a plastic material. The moulding technique allows the lifting heddles to be formed with varying cross-sectional dimensions according to the required strength of a given area. Reinforcing members may also be embedded within the lifting heddles to further increase its structural strength.

Abstract: The frame staves (1, 1') of a heald frame have ribs (12, 13) on opposite sides of the stave extending toward the center of the frame. Movable holding elements (5, 26) on the staves include guide plates (6, 7) extending over the sides of the staves and having inbent edges (10, 11) that grip the ribs. The holding elements are drawn up against the staves by screw and spring arrangements.

Abstract: A frame stave for the head frame of a weaving machine is extruded with a closed, internal T shaped channel 10 in its upper edge. When the location of connecting hooks 5 is determined, a portion of the top edge of the stave is machined away at 6 to enable the hooks to be attached to the stave by screws 8 and sliding inserts 9 within the channel.

Abstract: A frame stave for a weaving machine heald frame is provided with an insert 4 or 6 to maintain the side walls 1, 2 under tension and thereby damp out resonant vibrations in the stave to reduce the operating noise level.
