Abstract: In a device for driving the weft-inserting needles of a shuttleless loom in a rectilinear reciprocating movement, each needle is connected to the needle-actuating system by means of a flexible connecting member or so-called flector and is guided within a rail by means of a block of antifriction material attached to the end of the needle. By means of the device, vibrations of the driving mechanism are not transmitted to the weft-inserting needle at high operating speeds of the loom.

Abstract: In a shuttleless weaving loom of the double layer type, the position of the heald eyes and the relative displacement of the harness shafts which carry the eyes are such that, in the bottom position of the lower layers, the center-lines of the segments of the two layers, which are located between the rearmost position of the weaving loom and its intermediate position corresponding to the beginning of introduction of the weft threads into the sheds, both pass substantially through the pivotal axis of the reed.

Abstract: In a loom comprising a shedding harness with heald frames for forming two superposed sheds in incoming warp, weft inserters for traversing weft through said sheds, a reed for heating up the weft whereby to form upper and lower fabric, and a breast beam having upper and lower edges over which said upper and lower fabrics are taken off, respectively, there is provided a rectilinear elongate transverse member which may be a rigid rod or a tight thread and is supported through its two ends, for example by fixture thereof to two supports integral with the loom frame, across the space included, on the one hand between the two sheds and, on the other hand between the leading heald frame of the shedding harness and the location of the reed in the back position.

Abstract: A loom is provided with a longitudinal sliding surface over the entire length of travel of the outer extremity of the needles and behind these latter; the coupling system which connects the driving member to the outer extremity of the needles comprises a shoe which slides over that face of the longitudinal surface which is directed towards the needles; an oscillating arm which drives the needles is urged elastically so as to apply the shoe against the longitudinal sliding surface.
