Process for the production of goods provided with pile loops,

The invention relates to a method for producing goods provided with pile loops a warp knitting machine.

The previous approach was to produce the pile loops with additional, so-called plush needles. It The disadvantage here is a correspondingly large spacing of the needle bar in order to achieve a greater pile height to provide for dtn plush needles, with which a correspondingly large guide bar swing is connected, which the machine speed adversely affected.

Another known method is based on the fact that the pile thread is not involved in the formation of the basic goods Knitting needles are placed and discarded. This results in restrictions in the fineness of the goods as well as in

the pole height. Furthermore, not all linking groups can are made from warp knit plush.

The object of the invention is to find a method in which the mechanical effort is as low as possible is held and with any fineness of goods practically no restriction in the Pojhöhe and in the choice of Basic bond is given.

A solution has been found in the fact that during the production of a basic knitted fabric worked with at least two guide bars on a Raschel machine with double oscillating movement of the guide bars per row of stitches the pile threads for looping at two points each one knitting needle once from the one and to the second to be clamped by the other plain weave thread. It has proven to be particularly favorable to form the basic knitted fabric from a fringe and a weft thread.

This new method enables you, e.g. with a simple Raschel machine, which in In some cases it is equipped with a fall plate, and at least three guide bars get by, which swing in twice per row of stitches. The fineness of the goods and the pile height can be freely selected and depending on the way in which it is used

bind the pile thread is geiegrfr, as a stitch, as a handle or

ale Schufiitadsrc, the bond strength of the

Poles and the pole surface weight can be varied.

The drawing shows three different exemplary embodiments for a method using one each Laying pattern and a section of a Raschel machine in the area of the knitting needle illustrated.

In the novel process, the first pinch point on the knitting needle is created by the weft "forming, the second thread of the basic knitted fabric through the mesh. The two clamping points clamp the pile thread

system * '"so that when the needle bar is lowered, the thread path between the clamping points and the upper edge of the knock-off raises itself to form the pile loop.

The clamping points can be arranged regularly or at intervals, e.g. in every row of stitches or in any consecutive. The height of the bottom is variable, firstly because it is relatively high Thread tension of stitch and weft is applied, the better the clamping to the above Points and thus causes higher pile loops. On the other hand, the needle stroke can be made larger, all the more The pile loops become larger, as the distance between the

Clamping points to the upper edge of the tee is enlarged. The exemplary embodiments described below are in the drawings on the basis of a layout diagram, a list of chain links and a section shown from the Mascheabildungstelle of the machine.

In the embodiment of Figures 1 and 2 is the production of a so-called weft plush. Here, the _{front guide bar L 1} creates a fringe, the rear guide bar L2 a weft lay with considerations, but these are pressed by a fall plate onto the needle shaft, while finally the rear guide bar L3 guides the pile thread in weft. After the needle bar has been knocked off, the knitting needles rise to their highest point. The guide bars swing in their first swinging motion through the knitting needle gaps from the front of the machine to the back. The guide bar L «carries out a reflection. Then this guide bars swing to the front of the machine back and the fall plate comes into action, it descends and shapes the idea of the guide bar L ₂ in a bail order, ie the consideration enters the guide bar L ₂ of the tongue from the needle shaft. Thereupon the fall plate rises while the guide bar L carries out an underlay. Now the guide bars swing again at the second swing to the rear of the machine. The guide bar L ₁ carries out a consideration. The guide bars swing back to the front of the machine. The downward movement of the knitting needles begins and the two clamping points are created on the needle shaft, which can be seen from FIG. At the clamping point the weft thread is in front of the pile thread and at clamping point 2 the stitch thread is in front of the pile thread. When lowering the

The pile loops are created by a needle bar. The needles close and the guide bar I ₂ carries out an underlay and then the stitches are knocked off.

The embodiment of FIGS. 3 and 4 illustrates the production of so-called mesh plush. No fall plate is used here. The front guide rail L ₁ guides the pile thread that makes stitches. The laying bar Lp behind it leads to a fringe and the laying bar L at the back leads the weft thread,

This after the knockdown position of the needle bar rises / again to its highest point. The guide bars swing through the knitting needle gaps from the front of the machine to the back when they swing in for the first time. The guide bar L ₁ carries out a consideration, whereupon it swings back to the front of the machine, where it is followed by an underlay, contrary to the previous consideration. Then the guide bars swing again in the course of the second oscillation towards the rear of the machine. The guide rail Lp

carries out / a consideration, whereupon the guide bars swing back to the front of the masohine. The downward movement of the needle bar begins, creating the two clamping points on the needle shaft. When the needle bar is lowered, the pile loops are created and the needle tongue is closed • followed by an underlay of the guide bars L. and L, with subsequent knocking off of the stitches.

As can be seen in Fig. 4, this is due to the

übe ^ clamping point 1 of the weft thread behind the pile thread and at the clamping point 2 the stitch thread also, behind x the pile thread.

The third embodiment of the novel process, illustrated in FIGS. 5 and 6, illustrates the production of so-called handle plush. The Raschel machine used here is again equipped with a fall plate. The guide bar L ₁ lying in front guides the fringe thread, the Lp behind the pile thread, which makes considerations which are pressed onto the needle shaft by the fall plate. The guide bar L at the back guides the ocimus thread. After the needle bar has been knocked off, it rises again to its highest point * - The guide bars swing from the front of the machine to the back when they first swing through the knitting needle holes. Now the guide bar L ₂ carries out a consideration. The guide bars then swing back to the front of the machine and the fall plate comes into action, it lowers and transforms the _{guide bar L 2} into a handle, ie it pushes the guide _{bar L 2} from the tongue onto the needle shaft. Then the fall plate rises, while the guide bar L ₂ carries out an underlay, but contrary to the previous consideration. The guide bars then swing towards the back of the mesh in the course of the second oscillation. The guide bar]

carries out a consideration. Then the guide bars swing back to the front of the machine and it the downward movement of the needle bar begins and the formation of the two clamping points on the needle shaft. At clamping point 1 the weft thread is behind the pile thread and at clamping point 2 the stitch thread is in front of the Pile thread. When the needle bar is lowered, the pile loops are created and the needle tongue closes and finally underlays of guide bars Lp and L ,. JB Then the knocking off of the stitches takes place.
