Description

Known combined bumps for fabric shirring machines, including a support plate connected to the wrist chain with a spring-loaded valve pivotally connected to it, fitted with a breaker shank, edge-holding needles and a clamp for fabrics, have a complex structure and do not provide during the work the holding of the fabric edge with all the button widths machine chains, which adversely affects the quality of the fabric.

In the combined combination described, this disadvantage is eliminated by the fact that the edge retaining needles are fixed at the free end of the valve and pointed at the bottom, and the fabric clip is made in the form of a roller fixed to the valve located between the axis of rotation of the valve and the edge retaining needles, and for complete closing valve with the surface of the support plate, the latter has an opening for the passage of the roller and the hole for the passage of needles.

FIG. 1 shows a combined screw die, the general view; in fig. 2- support plate, top view; in fig. 3 - valve with roller, top view.

The combined die consists of a base plate / stamped from a sheet material, one end of which is cut and bent into a fork 2. This part of the plate 1 serves to fix the screw to the links 5 of the endless plate chain with which the tips are moved during operation. The other end of the support plate / has an opening 4 for the passage of the valve roller and the hole 5 for the passage of the needles, and in the middle of the plate; The windows 6 are located for the attachment of the valve 7 to the on / off plate.

The valve 7 is a plate, at one end of which, on both sides, hooks 8 are stamped and bent, with which valve 7 is hingedly attached through windows 6 to the support plate of Love No. 118803-2 -

At the same end of the plate, from the same end, the flange 9 is bent upwards, to which the fender liner 10 is attached. At the other, free end of the valve 7, the strip 11 is fixed with edge-holding needles 12, pointed at the bottom, and between the axis of rotation of the valve 7 passing through hooks 8, and the edge-holding needles 12 on the valve 7 in the lateral legs 13 bent off, the roller 14 is fixed.

For complete closure of the valve 7 with the surface of the support plate / on it, the curved flat spring-loaded springs 16 are fixed on both sides by two screws, which are pressed against the valve 7 with free ends.

Each screw plate in the distribution chain operates as follows. Prior to approaching the tissue to the fabric, its jacking shank 10 is bent off by an abutment (not shown) mounted on the width of the valve, and lifts the valve 7 so that between the roller 14 and the support plate / there is a gap in the mouth to allow free passage of the edge of the fabric into it. When the fabric enters the throat of the screw clamp, the stop of the brushing layer ceases to act on the breaker shank 10, as a result of which the valve 7 under its own weight and the springs 16 rests with the roller 14 on the cloth. Needles 12 at this moment do not reach the fabric.

When breeding schirilny chains in the field of shchireni, fabric gradually comes out from the silt and into. that moment when the fabric comes out from under the roller 14, the latter will fall into the opening 4 of the support plate 1, and the valve 7 will fall onto the support plate /, piercing the fabric edge with needles 12. At the same time, the needles 12 enter into the opening 5 and firmly hold the fabric during its grip.

When the fabric leaves the scribal mask, another stop (not shown) of the width mask deflects the fender shank 10, the latter lifts the flap 7 with the needles 12, and the fabric is released.

The subject of the invention.

Combined die stock to schirilnym maschinam for fabrics, include compounds with schirilnoy chain support plate with scharnirno connected thereto a spring-loaded valve provided with pneumatic shank kromkouderzhivayuschie needle and clamp the tissue, characterized in that, in order to simplify the design and the Enhance quality fabric schireni , the edge-holding needles are fixed on the free end of the valve and directed pointed downwards, and the clip for the fabric is designed as a roller fixed to the valve, located between the axis of rotation of the valve and edge-holding needles, in order to completely close the valve to the surface of the support plate, the latter has a hole for the passage of the roller and the opening for the passage of the needles.
