Lathe device for a shuttleless double weave loom

The invention relates to a device of the type described in the preamble of claim 1. A dean Establishment of this type according to DT-PS I 949> oo represents practically a doubling of a likewise previously known device for the production of leno fabrics of simple fabrics, which are described in "Production of leno fabrics" by W. Boos, Konradin-Verlag, 194j5, p. 48 ff is described. In this previously known device, the leno thread needles are in one of the dobby controlled shaft, while the associated guide blade makes a horizontal movement, so the to obtain basically required double relative movement in vertical and horizontal direction. Of the known device has the disadvantage that you practically need two larger units, each are driven for themselves movable, namely once the shaft for the lathe needles and on the other hand a frame-like Part that carries the leader sheet.

It is known from DT-PS 165 2o ^l 3, for the up and down movement provided with a fixed Nade.ln

To use frame or shaft, and to provide machine-fixed pivotably mounted needles, which the looping movement the leno threads cause the ground threads.

The invention starts from this latter known arrangement for producing won leno fabrics on simple woven webs of, and forms the well-known device such further characterized in that it is usable both for the production of leno fabrics on double fabric, as can be technically trained in self-contained unit as what is not possible with the known principle mentioned at the beginning for obvious reasons. The invention consists in that, in a manner known per se, the guide blade is fixedly arranged on a shaft with this up and down, and that the leno threads can be inserted into the double fabric with the shaft movement from above or below on the same shaft, at their tips the leno threads leading forks are pivotably arranged transversely to the guide direction of the sheet.

This offers the possibility of producing, for example, both Drenerkanten on one side of the Double fabric to build a self-contained device that has both the leader sheet and at the same time the leno thread needles pivoted on it in the form of forks or combs.

Appropriate refinements of the invention are described in the subclaims.

In the following the invention is explained using an exemplary embodiment with reference to the drawing, wherein the drawing in a schematic front view of the right leno of a shuttleless loom for double fabrics shows.

With Io a shaft is referred to, which in the usual Way can be moved up and down through the dobby. In the shaft is in the area of the two selvedges of the double fabric, a carrier 11 is arranged with the known guide sheet. Run through the guide sheet the edge warp threads of the double weave, which thus form the ground threads.

The carrier 11 is pivoted on two stub shafts I ^ the upper and lower thread guide fork 12, which in the manner known to the person skilled in the art alternately in the Immerse tissue as it is forcibly connected to the shaft Io be moved up and down.

To generate the horizontal component of the leno thread movement relative to the stationary threads, one now swings in the work cycle the two forks 12. The upper fork 12 is above its rotatable mounting at I ^ addition upwards extended and carries a sliding block 16 at the end. The sliding block runs in a vertical guide 17, which is in turn attached to a rod 18. The rod 18 is in accordance with the double arrow indicated there horizontally movable, whereby the pivoting movement of the up and down with the shaft Io is now evident Needle forks 12 is generated. In the area of the pivot point at 13 of the upper fork 12 is a Art extension 14 from. A similar extension 14 also carries the lower fork 12. The two end points of the extensions 14 are now rotatably coupled by a push rod 15. Of course it is Movement of the rod 18 adjustable in terms of both its stroke and its zero position, which is analogous also applies to the push rod 15, so that the turning

direction is universally applicable.

Since every double plush loom has at least one shaft anyway, which is the vertical component of the Thread entanglement, existing double plush machines can be made with the help of the inventive concept easily equip with the arrangement according to the invention. It must be assumed that a double plush machine also basically has at least one reciprocating machine part, which supplies the horizontal component of the leno thread loop. So you want the compact unit according to the invention install it in an already existing machine, there are therefore no difficulties because the two fundamentally separate drives for the two components of the thread looping movement available.
