Claims priority, application Switzerland Mar. 26, 1958 1 Claim. (Cl. 225-41) The present invention relates to a frame for mounting a warp tying machine for tying the ends ofv used warp threads to new warp threads.

Warp tying machines are known for individually tying the threads of a used warp to the corresponding threads of a fresh warp. These machines are placed on frames including clamps for holding the two warps and rails for movably supporting the tying machine. The frames run on rollers for moving the frames alongside the warp beam ends of the looms. The space between two looms is usually very limited. The warp beams radially extend beyond the lateral shields of the looms so that, at the elevation of the warp beams, the uprights between the foot portion and the top portion of the frame for supporting the used up warp, the new warp, and the tying machine must be placed substantially in the middle of the foot portion as seen in the longitudinal direction of the frame. Thus constructed frames cannot be moved very close to a loom because the uprights abut against the back rest of the loom. This causes an increased waste of the warp material which is costly. In another conventional frame for supporting the used up and the new warp as well as a warp tying apparatus the upright is placed at the end of the foot portion which is distant from the loom. Such frames cannot be moved between two looms unless they are widely spaced.

It is an object of the present invention to provide a frame for supporting a used up warp, a new warp, and a warp tying apparatus which frame can be moved between closely spaced looms and which can be placed so close to the loom carrying the used warp that the warp thread waste is negligible. In the frame according to the invention the top portion carrying the tying machine is supported on a foot portion by uprights which are inclined as seen in the longitudinal direction of the frame and which are connected to the side of the top portion which is distant from the loom carrying the used warp and which uprights are mounted substantially in the middle of the foot portion.

The novel features which are considered characteristic of the invention are set forth with particularity in the appended claim. The invention itself, however, and

additional objects and advantages thereof will best be understood from the following description of an embodiment thereof when read in connection with the accompanying drawing, in which:

Fig. 1 is a schematic end view of a frame according 'ice to the invention in the position in which it is moved between two looms;

Fig. 2 shows the frame in working condition and adjacent to the loom carrying the used warp.

Like parts are designated by like numerals in the two figures of the drawing.

Referring more particularly to the drawing numerals 1 and 2 designate the lateral shields of two juxtaposed looms for weaving between which the frame according to the invention is placed. The flanges of the warp beams 3 and 4 of the two looms extend into the space between the looms. The frame for supporting the warps and a warp tying apparatus consists of a top part 5 carrying the two warps, two carriers or legs 6 and two feet 7 resting on swivel rollers 8. The lower ends of the carriers or legs 6 are connected substantially to the mid.-

dle of the feet 7, the legs extending upwardly in an inclined direction with respect to the vertical to the top part 5. The inclination of the legs 6 is so that the feet 7 can be moved much farther into a loom below its warp beam than if the legs 6 were vertical. In other words, the legs 6 are in a reclining position affording pushing of the feet supporting the legs underneath the warp beam of a loom. The oblong top portion 5 of theframe has a longitudinal marginal front portion 5' on the side facing the loom 1, to the used warp threads of which new warp threads must be tied, and a longitudinal marginal rear portion 5" on the opposite side of the top portion 5. The upper ends of the legs 6 are connected to the marginal rear portion 5" of the top part 5.

Fig. 2 diagrammatically illustrates the frame in the operating position for tying the warp threads. In this position the frame is so close to a backrest 11 that the carriers 6 abut the backrest. Depending on the structure of the loom the carriers 6 may first abut the shaft 9 of the warp beam 3 or a brake drum of the warp beam, not

shown. In any case, the frame can be moved closer to a loom than is possible if the carriers are placed in vertical position on the middle of the foot portion. The result of the new arrangement is that the knots made by a diagrammatically illustrated tying apparatus 10 are very close to the end of the fabric so that the thread waste is reduced.

I claim:

A mounting frame for a warp tying machine for looms for weaving, comprising an oblong top portion having a longitudinal marginal front portion, said top portion having a longitudinal marginal rear portion distant of said marginal front portion, a plurality of foot members spaced from and placed beneath said top portion, and a plurality of leg members connected at their lower ends, one to each foot membensubstantially at the center of the foot member, said leg members being in a reclining position and being connected at their upper ends to the marginal rear portion of said top portion.
