Abstract: The present disclosure provides a weaving method of a weft-backed jacquard fabric with color shading effects and belongs to the technical field of weaving methods. In a single-warp and double-weft structure with a weft yarn arrangement ratio of Wefts A and Wefts B of 2:1, by designing two groups of face weaves and backing weaves and corresponding backed points and using a shaded strengthening method, two color shading effects of color shading of the Wefts A and mixed color shading of the Wefts A and the Wefts B of the fabric are achieved. A maximum number of shaded weaves is [R/N(6R?2J2?J1?3)+2], and a grade number of shaded color is less than or equal to the maximum number of the shaded weaves. The designed fabric meets the covering requirements and can be mass produced.

Abstract: A textile is formed from interwoven electrically conductive and non-conductive yarns to provide an array of connection points on one or both surfaces of the textile, facilitating the connection of electronic components to the surface of the textile, in an array. The textile comprises a multi-layer warp having electrically conductive and non-conductive yarns and a weft having electrically conductive and non-conductive yarns. At least some of the electrically conductive weft yarns cross selected electrically conductive warp yarns without electrical contact therebetween by being separated from the electrically conductive warp yarns by at least one non-conductive warp yarn in each layer of the multi-layer warp. Loops formed by the electrically conductive weft yarns provide electrical connection points together with proximal portions of electrically conductive warp yarns.

The solenoids control selector members and place them either in a deployed position or a withdrawn position. When the device is moved with respect to the needles of a Jacquard machine, those selector members that are in the deployed position engage pushers to move the associated needles.

Abstract: A method for representing optically a fabric consisting of warp and weft threads and with a pattern. To optically represent the fabric, the pattern is acquired by scanning from a model, or from an existing data carrier, or represented directly on a computer display. A crossing scheme is then assigned to the warp and weft threads. The course of the warp and weft threads is then determined by varying at least one of any parameters specific for the thread, such as the number of color components of a single thread and their distribution, the construction of the thread's surface or the material of the thread and by varying at least one of any parameter specific for the fabric, such as the closeness of the warp and weft threads, the advance of material in weaving, the sequence of the warp threads or the control functions for a weaving machine.

Abstract: A process of designing and weaving fabrics with pattern repeats over the full length of the fabric such as draperies or bedspreads. The pattern can incorporate one or more actual patterns within the repeat to reduce waste and inventory requirements for fabricators. The pattern repeat is typically incorporated into fabrics having a length greater than 50 inches. The design process is computer-aided to create an engineered repeat in the fabric panels which are then woven using an electronic weaving machine. Individual patterns are repeated across the width and length of the woven fabric.

Abstract: A process for determining the arrangement and step sequence of heald shafts of a heald loom for weaving a fabric including a backing fabric having a fabric pattern and an ornamental design. The ornamental design of the fabric is plotted and/or displayed by means of a computer. Alternatively, the combined appearance of the ornamental design and the fabric pattern may be plotted and/or displayed. Next, the number of heald shafts necessary for weaving the ornamental design or the combined appearance is determined. Heald shaft arrangements that are conventionally used and/or available which will weave a fabric design similar to the ornamental design or the combination designed are plotted and compared with the heald shafts determined for weaving the ornamental design or the combination design. The step sequence of the individual heald shafts in the heald loom from the assigned heald shaft arrangement is determined.

Abstract: In loom control for weaving a preselected pattern design or the like, electronically controlled electric actuators (1,10) are programmed for required operation in accordance with the pattern by a computer, each actuator (1) being connected to a warp thread (W) or to more than one such thread of the shed (S) for positive operation of the threads (W) in effecting required shed formations in weaving the pattern. A flexible connection member (2) between the actuator (1) and an eye member (3) receiving a warp thread (W) may be arranged in an endless manner for positive operation of the eye member (3) in either direction. In the case of a knitting machine each actuator is connected to one or more yarn feeders and/or to the carriage or carriages of the machine for their operation in knitting the preselected pattern.

Abstract: A method and apparatus for generating a pattern for making rugs corresponding to a predefined image. The predefined image is scanned by a video camera to generate a video image corresponding to the predefined image. A frame grabber captures one frame of the video image. The captured image is isolated and compressed by a CPU into a compressed image corrresponding to the video image and having a limited number of subareas, each subarea having a color. The CPU compares the color of each subarea to the colors in a look-up table to define a 48-color image. A printer creates from the 48-color image the pattern corresponding to the predefined image and an inventory identifying the numbers and colors of yarns needs to make a rug from the pattern.

The knife device is connected in a drive arrangement with a shaft drive of a weaving machine and the selecting device has coupling means which are formed from the lifters and electromagnetically actuated control projections. The coupling means arrest the lifters in a starting position which corresponds to the stroke position which opposes a pretensioning force of the single heddles. The electromagnets of the selecting device are connected with an electronic pattern control apparatus.

Abstract: A knitting machine provided with patterning mechanisms responsive to pattern-control signals is caused to produce a non-repeating pattern by generating the pattern-control signals randomly, using a random signal generator not operating in synchronism with machine operation and generating potential pattern-control signals, from which actual pattern-control signals are derived in synchronism with machine operation. Although the pattern-control pulses are randomly generated, the overall character of the pattern produced can be altered by adjustment of the random signal generator to thereby alter the probabilities in the random generation of potential pattern-control signals. Also, pattern restraints are imposed upon the randomly produced pattern-control signals in both the horizontal and vertical directions, involving the number of consecutive stitches of a certain type that are to be permitted to adjoin in one course and in one wale, this being selectable in a manner not detracting from randomness.

Abstract: The Jacquard machine employs a selector system for blocking and un-blocking the pressers (e.g. Jacquard needles) wherein use is made of a control means comprised of two electrically magnetizable relatively movable rods. Upon energization of a magnetic field generator, the rods move away from each other so that one of the rods is moved into a blocking position relative to a presser needle. Upon de-energization of the magnetic field generator, the rods come together so that the presser needle is unblocked.

Abstract: The Jacquard machine employs a selector system for blocking and un-blocking the pressers (e.g. Jacquard needles) wherein use is made of pivotally mounted locking levers between a control element and each presser. The control elements which may be in the form of multimorphous bending strips or a switching means comprised of two electrically magnetizable relatively movable rod-like members, engage with the levers to cause pivoting of the levers into a blocking or non-blocking position relative to the pressers.
