Abstract: A patterning method and device has yarn guides for guiding pattern yarns in a warp knitting machine and divisional fall plates for knitting pattern yarns in a fall plate structure individually drive-controlled through drive devices. The device comprises any number of moveable bodies having yarn guides, the bodies being installed for movement along a row of knitting needles by the drive devices. For patterning, the moveable bodies are moved through a desired distance along the row of knitting needles so as to be positioned for patterning, thereby providing a patterning zone for pattern yarns corresponding to the number of yarn guides. Thus, it is possible to effect a free varigated patterning which is comparable with the patterning effect provided by the Jacquard control.

Abstract: A device for clamping and guiding crocheting needles for a crocheting machine. On the one hand a clamping device for the crocheting needles and on the other hand a knock-over comb are to be created, which permit a very fine spacing. To this end, in the bottom part (27) and in the clamping cover (29) of a clamping device (12), opposite, straight needle beds (73, 74) are arranged closely together. The needle beds (73, 74) have wall surfaces that are inclined in a V-shape. A knock-over comb (20, 80) fixed to the machine has upwardly projecting teeth (86) for the crocheting needles. The spacing of the needle beds and guide elements is at least 12, in particular 14 per centimeter of machine width. The holding bar (23) fixed to the machine and the bottom part (27) of the clamping device (12) have recesses, in particular chambers (77, 76) that face one another, which permit the clamping device to move too close to the teeth (86).

Abstract: A warp knitted fabric is formed with pile. The ground fabric is formed by a first ground lap with threads (11) forming stitches (18) with a separation of n wales (19), and a second ground lap with threads laid-in and running in the same direction. The pile is formed by a pile lap, in which each thread (12) forms stitches (18) with a separation of m wales (19). Herein, n is at least 1 and m is at least 0. In a process for the preparation of warp knitted fabric, the lay-in is so provided that the successive turn-around points of the lapping movement has a separation of approximately n+1 needle spaces. A warp knitting machine comprises a first ground guide bar (L2), a second ground guide bar (L1), a pile guide bar (L3) and a pile sinker bar (PB) with the appropriate displacement control arrangements (14 through 17) which operate in the manner of the foregoing displacement movements.

Abstract: Warp knitting machine with a guide bar executing an oscillation movement and a base shift movement. Single thread guides are mounted thereon and are individually movable in a to- and fro- motion in the shift direction and are combineable into one or more groups and are group-wise adjustable by electrically controlled control motors under the influence of a program control having a pattern shift movement stored therein. Each of the control motors is connected to the thread guides of at least one group by a pull control cable held under tension which extends over the length of the guide bar and is further connected to the thread guides such that all thread guides of any one group execute the same pattern shift movement. The control motors are structurally supported independent from the guide bar. The pull control cables are guided from the guide bar at right angles and then deflected toward said motors.

Abstract: A warp knitted fabric has threads of a ground thread system forming a fabric ground. A pattern thread system also forms different patterned areas both in the weft direction as well as in the warp direction. In a basis area there is provided either cloth lapping (1-0/2-3-1 or 0-1/3-2-1). In the patterned area, a sequence is built by different lappings selected from a group consisting of pillar, tricot, cloth, satin and velvet stitches, in which the average length of the underlaps in predetermined pattern repeats is substantially similar to the underlap length of the cloth lapping. This gives rise to numerous new patterning possibilities, in particular for a jersey fabric. In addition to a described process, a warp knitting machine is provided for making such warp knitted goods.

Abstract: In a warp knitting machine at least one swingable guide bar is driven in a shogging direction. This displacement is achieved through a drive member via a hinged push rod in dependence upon a path time function. This path time function is formed by overlapping a ground function with a compensation function. The ground function is the targeted displacement movement of the guide bar for proper lapping. The compensation function compensates for an axial mislap and possible collision during the swing-through of the guide bar. The compensation occurs at least during that segment corresponding to the passage of the guides through the needle gaps. Preferably however, compensation occurs over the entire ground function. This compensation substantially reduces the danger of collision between the guides and the needles.

Abstract: Warp knitting machine with guide bars adjusted according to a pattern by means of displacement stepping motors, which receive their displacement information in the form of a certain number of displacement pulses from a pattern memory of a control device.For determining and correcting the guide bar position of a warp knitting machine shut down in underlay position, the indicator of an electrical proximity switch is connected with each guide bar, whose sensor is mounted on a measurement slider shiftable in the displacement direction of the guide bar, said slider being shiftable by means of a measurement stepping motor over the displacement range of the indicator beginning from a start position, which corresponds to the zero-position of the guide bar.

Abstract: There is disclosed a process for the manufacture of pile ware on warp knitting machine. The machine has a single needle bar and pile sinkers. The base threads and the pile threads are contemporaneously laid about the needles. During the swing associated with the underlap into the overlap position, first the base threads and then the pile threads are laid onto the needle backs and slid off from said needle backs with separation from each other. The pile sinkers are led into the space between the base and pile threads during the swing-through and remain there until the knock-over of the stitch. There is further provided an apparatus for carrying out the above process by means of a warp knitting machine for the production of pile ware. The machine has a needle bar, laterally displaceable bars for base and pile threads and a laterally non-displaceable pile sinker bar carrying a pile sinker interacting with each needle gap.

Abstract: The control member herein described comprises an electromagnet 30 which is fixed with respect to a thread guide rail and acts on a swinging arm 37 l pivoted with respect to the electromagnet itself and slidably engaging a lifter 14. Due to the energization of the electromagnet 30 the swinging arm 37, is brought, against the action of a return spring 39, from a rest position in which the lifter is disposed in a disengagement condition, to a working position in which the lifter is in an engagement condition and is engaged by actuator means oscillating in synchronism with the thread guide rail in order to cause the actuation of a threading tube associated with said lifter.

Abstract: The guide bars of a warp knitting/crochet warp knitting as well as the plurality of needles associated with such machines are automatically fully controlled for each full reciprocal movement in the knitting cycle of said machines. The pattern bars, yarn guides and needles are all moved in synchronism with each other and the rotation of the main machine drive to generate various desired patterns through a programmable memory with the capacity to store all the information required to position all the pattern governing parts in a series of juxtapositions which produce the desired patterns in the cloth fabricated by said machine. Said programmable memory means is integrated with a signal processing means generating signals which control the rotation of Servo-Motors; direction of the rotation of said Servo-Motors; rate of rotation of said Servo-Motors; and duration of each said series of rotations.

Abstract: In a warp knitting machine, warp stitch rows are formed from warp threads which are held together at least by a weft thread. Patterned threads are applied to the warp rows and are fed in a manner similar to the warp threads. For this purpose, a warp thread guide (18) and pattern thread guides (24) are positioned in front of the knitting needles and are moved over the knitting needles. At the sections of the knitting which are to receive a pattern, the pattern threads are applied on top of the warp threads resting in the needles and are knitted together. At the locations where no pattern is desired, controlled thread retainers prevent the insertion or threading of the pattern threads into the knitting needles and hence the knitting of the pattern threads in with the warp threads does not take place. At the pattern-free locations, the pattern threads are simply inserted into the warp stitch rows.

Abstract: Cam gear for textile machines, especially for pattern controlling of warp-knitting (chain stitching) machines. Generally, the development concerns a cam gear for textile machines having cams. The present configuration avoids the interferences, caused by oscillations, in the cam gears of textile machines. One advantage is that the occurring oscillations are influenced, and resonance phenomena are avoided, within the practical range of the normal rotation speed of textile machines.
