Method of production of multi-layer fabric

Method of production of multi-layer fabric lies in successive formation of one or more sheds, with simultaneous or sequential laying in them of weft yarns, beat of weft yarns to the edge of the fabric, retraction of the fabric and release of the warp. In order to reduce the load on the warp at beating, to improve dimensional stability of the fabric and the degree of filling it with yarns, and to reduce the fabric shrinkage in width, the beating of weft yarns is carried out with the open shed and the reed is retained at the fabric edge up to the subsequent laying of the weft threads. In order to stabilise the tension of the warp threads in the fabric formation cycle, the forced compensation of change in the length of the warp yarns is carried out in the shed independently for each branch of the warp and consistently with the position of the heald frame. When developing the layered-backing fabrics to reduce abrasion of warp yarns and simplify the system of management of retraction of the fabric, forming individual layers and their pulling to the other layers is carried out by changing the stroke of the movable reed, and the direction of pulling is set by tilting the movable reed when it moves to the edge of the fabric in the direction of the layer to which the newly formed layer is pulled.

The size of the geometric pattern on which is the connection of layers is carried out in one or two directions is 5-20 mm.

Multilayer moulding fabric with packed fibres

Invention relates to moulding fabric for the moulding part of the paper-making machine. Fabric has an upper layer of weft threads and a lower layer of weft threads, passing in a direction perpendicular to the direction of the movement of the fabric in the machine. Upper (moulding) layer and lower (side of wear and tear) layer are joined forming a multilayered fabric.

This arrangement of compacting threads also leads to the increase in transverse strength and seam strength and reduces transverse movement of weft threads on the side of wear and tear.
