Method and device for connecting warps.

Patented in the German Empire on April 11, 1905.

The present invention aims to simplify the connection of the warps and accelerate.

This goal is achieved in that the beginning and end of each chain BEZW. each Scheerganges enclosed in a known manner between strips of paper or cardboard which the threads at the beginning and end in very specific, by the division of the ίο Scheerrietes prescribed distances to each other hold and the ends of the old and new chain prepared in this way after being placed in a reed comb be connected by applying an adhesive.

The method with the associated facilities is explained in more detail below.

Fig. Ι shows a ^ linear representation of the cutting device with gluing device,
Fig. 2 the chain with glued-on retaining strips,

Fig. 3 shows the plan of Fig. 2;

FIGS. 4 to 7 illustrate the various working devices when drawing in respectively Connecting the new chain to the old one;

FIGS. 8 to 12 are individual representations of those used for connecting the new chain Contraption.

Between the Scheerriet α and the Scheerbaum b there is a pressing device consisting of the jaws d, d ¹ , which serves to press the retaining strips g firmly from above and below against the warp threads h at the given time.

This work must be carried out at the beginning of the shearing work and also when the respective passage to be sheared has the required length. In the latter case, two strips g of cardboard or similar material are to be placed next to one another at a small distance on the lower press jaws, which are coated with adhesive on their surface facing the chain h.

After two strips, which are also coated with adhesive, have been placed above the chain h , the press jaws d, d ^l are pressed firmly against each other, with the result that the strips g, g ^{l are} firmly glued to one another and the individual threads of the sheared thread are in the are held by the reed α certain distances from one another.

After the adhesive work, ie after opening the press jaws d, d ^l , the chain is cut between the two adjacent strips g , one of which forms the end of the chain that has already been sheared and the other the beginning of the chain to be sheared.

To connect the chain prepared in this or another known type to the reconditioned chain located in the loom, the device shown in FIGS. 4 to 12 is advantageously used. The same consists essentially of a bracket k, on which a double comb m, m ^{1 is} attached, which can be raised, lowered and rotated and is moved from below into the area of the old chain. The prongs of this comb must of course have the same distance as the threads of the chain to each other.

Claims (2)

Before the new chain to be connected is placed, the comb m, m ^{1 is to be moved} into the area of the old chain h 'so that only one warp thread comes to lie between each prong (FIG. 4). The old chain is then loaded by means of a rod ρ in such a way (FIG. 5) that it pulls itself down behind the crest m, m ¹ and is consequently held in the valleys of the prongs. Only now is the new chain h to be stretched tightly over the comb using a suitable tensioning device, which was previously tilted slightly to the side (Fig. 6) and is now to be adjusted by appropriate displacement perpendicular to the warp threads so that its prongs are exactly below the between the individual threads of the new chain h to stand free spaces and consequently when the comb is now to be erected, the threads of the new chain come to lie individually between the teeth of the comb. The movable comb m ^l is now to move on the retaining bolt η (Fig. 7) and now the new chain is loaded so that it lies in the same plane with the old chain h ^l so that the pairs of threads located in a comb gap immediately Come to lie on top of or next to each other. If glue is now applied between the combs m, m ^l by means of a brush or another tool, the threads lying in pairs in the comb gaps will stick together, and the connection between the new and the old chain is established. If neighboring threads pass through the adhesive . substance have been connected, this connection can be canceled again that the comb in ¹ is moved close to the comb m again before the adhesive dries. The shaft carrying the comb m is rotatable in bearings s and held on the uprights k by means of the adjusting screw t so that it can be displaced perpendicular to the warp threads, in which the bearings s can be moved up or down as required (Fig. 8, 9 and 10). The comb m ¹ is connected to the comb m by bolts η which can be moved parallel to the warp threads. Since only weak strips g made of cardboard or the like can be used to keep the warp threads in an orderly manner, which because of their slight flexibility do not allow the direct connection of the tension cords ν 55, it is advisable to use a rigid bar to hold these strips g straight w ' (FIGS. 11 and 12), which is hollow and only has a longitudinal slot in the middle through which the warp threads of the strip inserted from the side can pass.
