SU98981A1 - The method of sequential connection by nodes of the threads being modified and new bases - Google Patents

Description

The subject of the invention is a method for sequentially connecting the knots of threads to be developed and new bases, for example, on weaving machines with continuous fabric formation.

The proposed method, compared to the known, allows us to increase the productivity of weaving machines due to the better cross-knot through, remise and reed, and reduces the amount of waste of the ends of the finished and new foundations.

The peculiarity of the proposed method is that the nodes are placed with a mutual shift along and across the bases according to a given rapport of the location of the nodes, for example, along a single or alternating diagonal m facing in one direction or towards each other.

The proposed method involves the connection of the warp threads according to different rapports with a mutual shift of the nodes along and across the warps. At the same time, the ends of the threads of the jointed bases are arranged in one direction or oppositely, in contrast to the hitherto known and used in industry

mechanical or manual knots, in which the ends of the bases are located only in one direction.

FIG. 1 shows a rapport with a location of nodes / on a single diagonal.

With a mechanical viscous with a given step of displacement between the nodes of the height of the rapport along the base and a decrease in the density of the filling, the distance between the nodes across the base increases. Depending on the yarn numbers used and the densities of the dressings, the number of nodes in the repeat lines and, consequently, the size of the repeat along the base is determined.

FIG. 2 shows a combined rapport with alternating diagonals, diagonally-chess facing in one direction. This rapport consists of two diagonals of places of communication, moving in a checkerboard pattern. The number of diagonals included in this rapport and having an additional reciprocal chess shift between the nodes of / may vary depending on the allowed height of the rapport and its width, the number of nodes included in it and the distance between them.

FIG. Figure 3 shows a combined tarsional rapport with diagonals facing one towards the other, with the placement of nodes / in the form of triangles in which they are mutually shifted.

FIG. 4 shows a triangular raport, in which the nodes / placement of the LOTiCH is shifted in each of the two sides of the triangle with intervals, but without a shift between the nodes of the adjacent side.

The raiiort are repeated across the width of the base until all the threads are completely joined.

As follows from the foregoing, rapports can have different placement of knots and are selected in accordance with the requirements of the technology and their greatest simplicity for mecha- phic viscous knots.

The ends 2 and 3 of the joined bases can be directed towards each other (Fig. B) or in one side ((}: ig. 6).

In the first case, the ends 2 of the base being refined with a beacon and hinges 3, coming from the side, are located opposite and are held in this form in the clamps 4.

The length of the thread to form knots in rapport is constant, but since the shifts look at repeated Shifts between nodes by a certain amount from the ends of the modified and new foundations, a relatively different length of the thread corresponding to the amount of shift between the nodes is spent.

FIG. 5 shows a scheme for obtaining rapports of nodes from two bases clamped at the ends:

finalized, coming from the machine and the new osnrvy, going to the military. The numbering indicates the location of this node in the repeat on the threads of the upper and lower bases. As the length of the yarn of one base is reduced or increased, the consumption of the yarn from the other base also increases or decreases accordingly. The total length of the thread to shift each knot from the first to the last is constant.

FIG. 6 shows the arrangement of the connected warp threads with the ends to one side. And in this case, the constancy of the thread length is provided for all the rapport nodes.

The constancy of the length of the thread with the rapport knots creates the same tension on the thread on the weaving machine.

Subject invention

A method of sequentially connecting new and warped yarns with knots, for example, on weaving machines with continuous fabric formation, characterized in that, in order to ensure better knotted knotting of the warp knots through the working bodies of the weaving looms by a given rapport of the location of the nodes, for example, by single or alternating diagonal m facing in one direction or towards each other.
