A warp knit fabric structure formed by means of a single needle and a single guide bar made upon short hook needles of the latch or compound type in which one thread only is supplied to each needle and two, three, four or more needle wale overlaps are made at every course and only the last part of the overlap next to the guide eye forms a single knit loop on the needle of each last wale crossed, and by means of the geometrical settings of the machine knitting elements, the adjacent threads individual single needle loops, or the use of a point comb, the preceding part of each overlap is prevented from forming knit loops on the needles. This part of the overlap is divided into two components, a weftwise fabric linking traverse, and a residual warpwise part held in the adjacent wales by the double thread crossing of the neighbouring threads on each needle in every course of knitting, the fabric structure with only one single knit loop to each needle wale in each course, is obtained with bulk, fullness, and directional stability.

Warp knit fabric structure and method of production

A thread brake for a textile machine, in particular a shuttleless loom, in which weft thread lengths are withdrawn from a store disposed outside the shed, wherein interruption of weft thread take-off is carried out by displacement of a take-off roller 6 rotating at constant peripheral speed from an operative position to an end position remote from the thread 1. The device comprises at least for one brake shoe a movable holder 21 which is movable between two end positions in the direction of the gap towards a holder 21' of the other brake shoe and at least indirectly connected to the loom shaft 8 in driving relationship. The displacement of one or each holder occurs against the force of a spring 23 or 23' which in the unloaded state corresponds to a distance between the two brake shoes corresponding to thread thickness. The thread brake according to the invention has, due to displacement of the holder(s) and hence the brake shoes, in operation an automatic cleaning action on account of which the brake shoes are automatically cleaned of deposited fluff.

A thread gripper for a textile thread having a fork-like gripping member with two rigid horns 3, 7, of which the one horn 7 forms a rigid part of the thread gripper. A cushion 5 of soft resilient material is inserted in a recess 4 in the other horn 3. This cushion 5 presses a tongue 6, in order to grip the thread 11. The thread 11 is released by pressure on the nose 9 carried on top of the tongue.

A loom including a drive device for weaving fabric from warp yarn extending from a source over a back rest provided adjacent one end of the loom and after being woven into fabric being fed over a breast beam positioned adjacent the other end of the loom. A driven roll over which the warp is guided without slippage is disposed in front of the back rest and at least one driven delivery roller over which the woven goods is guided without slippage is disposed after the breast beam. The guide roller and the delivery roller are driven in synchronism and there is a driving connection therebetween, as well as with the main drive shaft of the loom.

A device for equalizing the warp yarn tension in a loom having a movable back rest and a fixed beam spaced therefrom. The back rest is moved to and fro the beam during the weaving operations with the warp yarns extending thereover. A pressure cushion is carried between the back rest and the beam parallel to the back rest and the beam. The pressure cushion is compressed and relaxed as the back rest moves to and fro said beam during the weaving operation for equalizing the warp yarn tension.

A method and apparatus for producing a selvage on a fabric woven on a loom in which filling threads are drawn from a stationary supply outside the shed formed by the warp yarns. The method and apparatus includes inserting a first filling through the shed. The ends of the first filling are clamped by a first pair of clamps positioned on opposite sides of the shed which hold the filling in an extended position. The filling thread is beat-up into the fell of the fabric and simultaneously the ends thereof are displaced behind the fell of the fabric for engagement by a second pair of clamps. The filling is then severed outside of the second pair of clamps so that the second pair of clamps continues to hold the ends of the filling in an extended position behind the fell of the fabric. The shed is then changed and the above steps are repeated until a predetermined number of fillings are held by the second pair of clamps. A selvage insertion needle which has a hook on the end thereof simultaneously engages the ends of the fillings held by the second pair of clamps and inserts the ends of the fillings into the shed. The plurality of fillings are beat-up simultaneously during the beat-up operation of the next inserted filling.

The beam of the slay of a loom is a hollow rectangle in cross-section; the reed is held against the outside of one wall of the slay beam; the reed comprises reed blades, whose opposite ends are each embedded in a hardenable compound in the bends of a pair of oppositely disposed, facing U-rails; a plurality of holes arrayed along and passing through one rib and the slay beam wall; at each hole a fastening means supports a flange that presses against the outside of the rib; each flange is generally rhombus shaped and curved to be flattened by tightening.
