Abstract: There is provided a warp knitting machine with a weft thread arrangement M having two jacquard guide bars 11 and 12. These are subject to shogging in the sense of a tricot stitch. In substantially each working cycle, a portion of the guides 13 of first jacquard guide bar 11 are displaced in the sense of a pillar stitch. The selection of the so displaced guides alters itself, but periodically. Thus certain needles 7 remain unlaid by warp threads of the first guide bar 11. The guides bar 14 of the second jacquard guide bar 11 lay warp threads around the said needle 11 left free by the warp threads of guide bars 11 while laying thread around other needles 7. This permits the provision of a patterned fabric which is exceedingly stable two-dimension.

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: A process for the production of warp knitted fabric uses a ground guide bar (L1) and at least two guide bars (L2 and L3) with partial threading. Threads (14) of a first additional thread system are worked with a main lap, which comprises a two row repeat. Threads (15) of a second additional thread system alternate between this main lapping and a pattern lap. Thread consumption in in the pattern lap are kept the same as in the main lap by using displacements that are larger and smaller than that in the main lap. A warp knitting machine (1) for providing such a process comprises appropriate control arrangements ( 6, 7, 8) for the displacement of the ground guide bar (L1) and the additional guide bars (L 2, L3). Furthermore, a novel warp knitted fabric is produced thereby. It is thus possible, by simple means, to produce a warp knitted fabric which is differently structured both in the warp direction, as well as in the weft direction.

Abstract: A patterned fabric includes weft threads 3 and a fabric ground whose warped threads 2 are laid in a first area 4 in chain stitch and in a second area 5 in another stitch form. The second area 5 alternates with the first area 4 both in warp as well as weft direction. This provides, despite patterning by the warp threads, a surface stable fabric. The process for forming the patterned fabric is such that the fabric, after production, has a longitudinal extension of no greater than 25% and additionally is provided with a longitudinally stabilizing, stability improving arrangement step.A warp knitting machine for the production of fabric 1 comprises a weft insert magazine and two jacquard guide bars. In substantially each working cycle a portion of the guides lay chain stitches and the remaining portion of the guides lay other stitch types. Substantially each guide lays sequentially chain stitches as well as other stitch types.

Abstract: A warp knitting machine for making pile ware having at least two guide bars carrying guides (L1, L2, L3) and a pile sinker bar (5) carrying pile sinkers displaceable in the longitudinal direction. The guides lay the threads forming the ground ware without crossing over the pile sinkers and lay the threads forming the pile loops by crossing over the pile sinkers. At least one guide bar (L1, L2) is equipped as a jacquard guide bar. The displacement of this guide bar, is so chosen that, in dependence upon the jacquard controls (9), the guides (6,7) can lay either a ground ware (15) or pile loops (14).

Abstract: A weft thread insertion arrangement for the weft thread magazine of a warp knitting machine has a warp thread laying insert carriage. The carriage, in conjunction and cooperation with the main shaft of the warp knitting machine, is driven between two forwarding devices for forwarding the laid weft threads to a needle bed. The arrangement has a drive assembly including a computer and a servomotor. The computer has at least one data storage device for taking up the data associated with at least one movement path formula. A sensor is provided for determining the number of revolutions and the angular displacement position data of the main shaft, which is fed back to the computer to enable it to compute the required drive speed of the servomotor.

Abstract: A process for the preparation of pile ware on a warp knitting machine wherein, the formation of pile on the front and rear of the goods is respectively achieved by a pile thread system. For the formation of a pile free allocation the threads of at least one pile thread system can in accordance with the pattern, be so individually controlled that upon a signal they can be laid about a first or a second needle. This may be achieved by means of a jacquard bar whose needles are individually steerable in accordance with the demands of the pattern by a jacquard arrangement. In this manner it is possible to obtain a desired patterning using a pile thread system.

Abstract: An arrangement can control displacement movement of a guide bar of a warp knitting machine or the like by means of a summation drive which, during the work cycle moves steering arrangements for underlap displacement and overlap displacement in a timely and appropriate manner. It comprises a first and a second overlap displacement control arrangement which operate in opposing directions and having a simultaneously operating underlap control arrangement, operating a switching mechanism which, upon choice, couples either the one or the other overlap control arrangement with the summing drive. If desired, there may be provided a third overlap displacement setting arrangement which is permanently coupled to the summation drive and optionally activated. In this manner, a variety of different overlap displacement patterns may be obtained with a lower switching frequency than once heretofore possible.

Abstract: A summing arrangement controls the underlap and overlap movement of a guide bar of a warp knitting machine. The arrangement has a plurality of ordered elements each having at least one curved face. The ordered elements are mounted on the machine to allow a variation in the spacing between each. Also included is a plurality of adjustable roller devices, one between each adjacent pair of elements. Each of these roller devices can roll upon and push at least one of the elements at its curved face. An overlap arrangement can move against at least one of the ordered elements to influence each overlap movement.

Abstract: A weft thread insertion magazine in a warp knitting machine has a pair of separated forwarding chains driven by a drive arrangement. These forwarding chains each have equidistant holders for holding transversely placed weft threads. The drive arrangement can provide the forwarding chains with a lower speed than the normal speed at which weft threads are provided to the needles, that is, at a rate less than one thread per needle cycle. In particular the drive shaft of the warp knitting machine may be connected to the forwarding chains by means of a revolution reducing arrangement. A control arrangement regulates the separation of at least the first weft thread from the others following and the presentation of this first one into the vicinity of the knitting needles. This control arrangement comprises either a weft thread presenter, a weft thread deflector or a combination of both. The control mechanism only activates the weft thread presentation or deflection during a portion of the appropriate needle cycle.

Abstract: A warp knitting machine has a needle bed and a jacquard arrangement for producing patterned wear from a plurality of threads. The machine includes a thread positioning bar and a plurality of thread positioning sinkers mounted on the thread positioning bar. The sinkers are spaced to allow the sinkers to pass between the needles of the bed. The machine also includes at least one guide bar and a plurality of thread guides mounted on each guide bar for separately guiding the threads. The thread guides are operable by the jacquard arrangement to move longitudinally relative to said guide bar and with a component of motion in a plane alongside the needle bed. This component is sized to allow each of the threads to reciprocate between and be pulled against the interior sides of a corresponding, neighboring pair of the sinkers.

Abstract: A guidebar shogging linkage arrangement for warp knitting machines includes a pair of shogging guides, each having slider bars movable in a longitudinal direction pivotably connected to a common keying element by means of a pair of elongated levers. A shogging lever has its position determined alternately by the position of the first slider bar and then the second slider bar which position is programmed into the shogging guide by means of a predetermined program fed to a jacquard mechanism. The shogging lever is capable of moving the guidebar in fixed increments parallel to the needle bar. The shogging lever also includes a means for adjusting the amount of incremental shogging distance for the same incremental setting of the guide apparatus. A compensating drive means may also be coupled to the shogging lever to compensate for arcuate movements of the shogging lever.
