Description

The proposed device for making straw mats is carried out by passing several layers of straw from the conveyor belt of the machine between rollers, followed by stitching the straw with wire and twisting and clamping the ends of the wire staples with periodically rotating forceps, receiving movement from gears mounted on the handle of the tongs .

In the schematic drawing of FIG. 1 is a side view of a part of a machine for manufacturing a carded tape with a device for making straw mats; FIG. 2 pliers to clamp and twist the ends of the wire clips; FIG. 3- modification of forceps for the same purpose.

On the supply conveyor belt 1, which receives a periodic movement from the main shaft of the machine, is exactly the same as the tape in the car that produces the card tape, it is laid in three layers of straw, which is compacted by rollers 2 (Fig. 1), which are fed compacted straw to the fixture making wire clamps and stitching straw, similar to that used in the card-yarn machine, only cheeks 4 (Figs. 1 and 2) and rods,

not shown in the drawing are made more solid. Periodically swiveling and opening tongs 16-17 (Figs. 1 and 2) with spacer spring 18 are used to clamp and twist the ends of the wire brackets that hold the straw together with the spacer spring 18 to close the tongs. The opening of the tongs 16-17 is carried out by the rotating cam 22. To periodically rotate the tongs 16-17 in the rack 19 there is a gear 20, which is attached to the long handle of the tongs and brought into periodic rotation from the main shaft of the machine. When the straw is stitched with a staple, the cam 22 presses on the handle 16 of the forceps 16-17, causing the forceps to open. Upon further movement of the cam 22, it moves off the handle 16 of the forceps, which, under the action of the spacer spring 18, closes the forceps and clamps and twists the ends of the wire brackets last (Fig. 2). In a modification of the tongs for twisting and clamping the ends of the wire brackets, the tongs have curved pins 16 and 16. The opening of the tongs is made by rotating wedge-shaped fingers 22, which are fixed on the rod 17, and the forceps are closed.

a spring 18 attached to the curved ends of the forceps. The tongs are rotated from the rod 17, at the end of which pinion 20 is mounted, which engages with gear 21, receiving movement from the main shaft of the machine through the connecting rod 27 and cam 28, mounted on the auxiliary shaft 24 (Fig. 3).

The subject matter of the invention.

1. A device for making straw mats on a card-making machine, characterized by using periodically pivoting and opening tongs 16-17 (Figs. 1 and 3) for clamping and twisting the ends of the wire brackets holding the straw, laid out on the supply belt 1 , for opening which tongs the rotating cam 22 is marked, for closing the tongs there is a spacer spring 18, and for periodical rotation of the tongs there is a gear 20 mounted on an elongated handle of the tongs drive into periodic rotation.

2. Modifying tongs for clamping and twisting the ends of the wire brackets in the fixture described in paragraph 1, characterized in that the wedge-shaped rotating fingers 22-22 (Fig. 3) are used to open the tongs, and for periodic rotation of the forceps serves gear 20, mounted on the end of the rod 17, at the end of which the fingers of the forceps are fixed
