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 warp knitting machine comprises a brake operative upon current interruption. The guide bars are displaced by an electrical setting motor as well as a control arrangement, which establishes the position of the guide bars in dependence upon the angular position of the main shaft. The control arrangement bases its control upon a predetermined displacement function relating the positions of the main shaft and guide bar. The setting motor and control arrangement are connected to a main power source via an intermediate circuit, which has at least one storage condenser. This machine allows for a rather rapid change of the lapping pattern and a continuance of controlled guide bar displacement right up to the standstill of the main shaft.

Abstract: A control arrangement for displacing the guide bar in a warp knitting machines comprises an input arrangement for the setting certain characteristic data defining the desired shogging pattern. There is also provided a first storage section for storing data for various transition curves also relating to shogging patterns. A computer can generate a continuous displacement function based on the characteristic data and the transition curves. An output arrangement can reads out the values of the displacement function in dependence upon the rotation angle position of the main shaft 7 of the knitting machine. The values this read out are used as position target values for the guide bar. This enables flexible adaptation to produce very different patterns in high machine speed.

Abstract: A warp knitting machine comprises at least one guide bar and one main shaft. The angular position of the main shaft is determined by an absolute transmitter, while the position of the guide bar is determined by an absolute transmitter. Each transmitter can provide a different signal value for each angular position of the main shaft and for each guide bar position. A continuous displacement function is developed for the guide bar. This function relates each measured angular position of the main shaft with a position target value for the guide bar. A position control circuit controls a setting motor that displaces the guide bar. In this way, the danger of collision between elements of the guide bars and other working parts of the machine are practically totally avoided.

Abstract: A partial wig has a fabric support to which the hairs of the wig are secured, the support being semi-circular with a diametrical straight edge. A barrette anchorage member comprises a folded over fabric defining a conduit extending along the straight edge of and stitched to the wig support. The conduit receives a spring member of a hair barrette having a base plate to which an ornamental bow is secured and a hair retainer which rotatably latches to the base plate with the spring and anchorage members sandwiched therebetween. The spring member resiliently engages a slot of the retainer, locking the hair of a wearer and the anchorage member in place. Different barrettes may be used with the same wig and anchorage member assembly or different wigs or head covers such as veils with their attached anchorage members may be used with the same or different barrettes in interchangeable relation.

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: 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.
