Abstract: Conductive wires or traces woven into a textile article as a warp or weft yarn are limited in directionality and beginning and end points. The presently disclosed woven electronic textiles permit electrical traces to begin and end at specific points within an interior of the textile and for runs of the electrical traces to extend continuously at any desired angle and connecting any number of specific points across a textile surface. Such electrical traces are referred to herein as point-to-point conductive traces.

Abstract: A loop-forming apparatus of the type including a plurality of loop-forming mandrels each extending forwardly between and in parallel to a corresponding adjacent pair of ground warp threads beyond the cloth fell of a weaving machine. The apparatus has at least one leno deflector extending transversely of the mandrels and reciprocally movable in a substantially transverse direction to that of the length of the mandrel so as to deflect the course of loop-forming warp threads alternately to one side and then to the other side of corresponding mandrels, respectively. A plurality of pairs of spaced gate hooks each extend vertically at opposite sides of the corresponding one of the mandrels and are vertically reciprocable in timed relation to the leno deflector to capture and lower the deflected loop-forming warp thread alternately to opposite sides of the corresponding mandrel so as to pass the loop-forming warp thread over the mandrel to thereby form pile loops on a woven fabric.

Abstract: Lancet holder for face-to-face weaving loom, comprising a slat-shaped section (1) onto which lancets (2) can be pushed. A comb (4) with teeth (8) lies directly in front of section (1). Each lancet (2)--extending in the warp direction--can be situated between two teeth (8), and the width of the space between two teeth (8) is slightly greater than the thickness of a lancet (2), so that they remain with their flanks at right angles to the section (1). Section (1) and part of the lancets (2) pushed onto it may be enclosed by a surrounding wall (9), (10) which is rounded off and smooth along the outside, and the comb (4) is set up along the front open side of said surrounding wall, so that the lancets (2) can extend from the enclosed space between the teeth (8).

Abstract: A leno or cross weaving texture is produced with a stationary warp thread and a cross warp thread which is alternately shifted from one side to the other of the stationary warp thread. The method of producing the leno weave includes the steps of providing a line segment of the stationary warp thread which connects first and second planes provided on the respective sides of the stationary warp thread, inclining the line segment of the stationary warp thread so as to cross a weaving plane alternately from an upper side of the first plane to an under side of the second plane, and from an under side of the first plane to an upper side of the second plane, and moving the cross warp thread in a perpendicular direction relative to the weaving plane and above the inclined line segment so that the cross warp thread is caused, during its movement, to slide along the inclined line segment towards the first plane or the second, thus producing the leno weave.

Abstract: A warp is prepared including a stationary thread, a crossing thread and an auxiliary thread, the latter two of which are laterally interlaced at a sliding connection and subject to being alternately tensioned and released for causing the crossing thread to cross across the stationary thread, and cross back, as conventional loom equipment is manipulated to create a succession of sheds into which wefts are inserted to weave a cross-woven textile fabric. As the weaving is being accomplished, a separating element is provided to prevent the sliding connection of the crossing and auxiliary threads from sliding so far towards the reed as to become incorporated in the fabric. The stationary or auxiliary thread may actually be constituted by a metal or other non-textile element, which is pulled out of the fabric as the fabric, having been woven, is moved downstream on the loom.

Abstract: An improved loop-forming assembly in a weaving machine for forming a surface fastener tape blank having a multiplicity of warp pile loops formed of loop-forming warp threads comprises: a plurality of parallel spaced lancets; a deflector extending transversely of and over the lancets; and a plurality of pairs of parallel spaced gate hook bars; the lancets, the deflector and the gate hook bars being kept free from one another. The deflector is axially reciprocable for laterally deflecting the threads in eyelets with respect to the lancets, respectively, and the gate hook bars are vertically reciprocable in timed relation to the deflector to lower the thus deflected threads by hook portions alternately at one side and then at the other side of the lancets so as to pass the threads over the lancets in a staggering fashion to form the warp pile loops.

Abstract: An improved mandrel for use with a weaving loom for the formation of loops of a looped fabric suitable for use as a surface-type fastener generally known as a loop-and-hook fastener. The mandrel has a generally V-shaped first recess defined in an upper longitudinal edge thereof and adapted to be disposed adjacent to the fell of a foundation fabric while being woven on the loom, for receiving individual loops therein before they are tensioned on a loop-setting portion. Since all the loops are received in the recess irrespective of their initial looping positions, a warp thread forming loops does not interfere with a weft thread forming a part of the foundation fabric and the loops are placed in a desired upstanding position when tensioned on the loop-setting portion.

Abstract: The carpet loom has pile wires extending warpwise with associated pile yarn transfer hooks for positioning preselected pile yarns over the pile wires for forming pile loops. The pile wires are pivotally mounted so as to be restingly positioned on the base fabric being woven to assure obtaining the desired pile height loop and to avoid undue tensions and stresses in the fabric being woven to assure smooth efficient loom operation. The transfer hooks extend rearwardly with their hook portions positioned substantially in a horizontal plane and inclined downwardly at an acute angle from the horizontal plane. This positional arrangement of the transfer hooks and the associated mechanism for imparting a reciprocatory movement to the transfer hooks permits an uninterrupted reciprocation of the reed to take place as well as the changing of the pile yarn and ground warp shed. This results in a high speed of loom operation of about twice the rate of prior carpet looms.

Abstract: A method and apparatus for weaving pile fabrics of the type whose pile tufts are formed by shogging pile yarns weftwise over warpwise extending pile wires. Two sets of pile yarns are employed extending through respective sets of pile yarn guides arranged in weftwise rows on a loom, and the pile yarn guides, with the pile yarns extending therethrough are pattern controlled in such a manner that, in the forming of warpwise extending rows of pile tufts on the fabric, pile tufts are, at times, formed in each row from one set of pile yarns and at other times pile tufts are formed in each row from the other set of pile yarns, and the pile yarn set which is not forming pile tufts is forming floats between the warpwise extending rows of pile tufts.

Abstract: Pile wires extending longitudinally of the fabric being formed and are arranged in side-by-side cooperating pairs of first and second pile wires, with only the first pile wires having cutting blades so arranged as to cut loops previously formed over both pile wires of each cooperating pair while they occupy a first position. Means imparts relative longitudinal movement to each cooperating pair of pile wires, and cooperating means on the pile wires is responsive to such relative movement of the pile wires to a second position for diverting the first pile wire laterally away from the second pile wire of the respective pair so that loops of pile yarn are formed over only the second pile wire and thus form uncut pile loops in the fabric.
