Description

The news rubber tool in a sewing machine for pulling the curved and sewn edge of the product around the retractable rubber braid, made in the form of an edge of the product with a ribbon of corrugated rollers, of which the upper is spring-loaded, and the lower is equipped with a lever from the main shaft of the machine with roller clutch freewheel.

Compared with the known installation, the installation is more economical in terms of the consumption of material, which is required for folding the edge of the product around the retractable rubber band, and mechanizes the folding of the edge of the product without additional bending.

The fixture is equipped with a knife switch installed in front of the machine's press foot, which bends the edge of the movable (1t served up the lever transfer tube that serves as a guide for the length of the rubber band sewn up in the curved edge of the product.

FIG. 1 is a diagram of a junction assembly with corrugated rollers; in fig. 2 - side view of the switch; in fig. 3 - view of the breaker in the plan; in fig. 4 - schema edges of the product.

From the eccentric (1), mounted on the main shaft (2) of the sewing machine, the movement of the connecting rod (3), pivotally connected to the lever (4), is transmitted. The lever (4) is attached to the pin (5), fixed to the body of the machine arm, and provided with a slit (6) for the ball pin (7), on which the occasion (8) is fixed. The lead (8) is connected to the end with a ball collar (9) located in the groove (10) of the process of the cover of the roller free-wheel clutch.

The axle (11) is reinforced corrugated roller (12). On the base (13) there is a stack (14) carrying an axis (15), at the end of which a roller (1G) is put on.

In the upper part of the pillar (14) there is an axis (17) on which the lever (18) with the arm (19) is mounted. The lever (18) has an axis (20), at the end of which a corrugated roller (21) is fixed. The axis (17) is provided with a handle (22) for lifting the corrugated roller (21).

In front of the press lanka (23), a switch is installed on the cup-e (23a) to bend the garment around a tube (24) attached to a bar (25) that is sharply connected to the bar (25a) attached to a square (26).

The square (26) from the bottom is equipped with a slit (27) in which a washer (28) is inserted, mounted on the axis (29).

A hook (30) is attached to the washer (28), on one side with a cable with a tube (24) on the one side, and with a foot pedal on the other side (shown on the NS diagram).

The product is transported by corrugated 1.1 lays (12) and (21) along the plane (31) and the edge of the product bends around the tube (24), through which the rubber band passes, sewn into the folded edge of the product.

When the foot pedal is pressed, the washer (28) turns and sets in motion the hook (30), which pulls the tube (24) through a cable (32) to secure the rubber band on the edge of the product.

The tube (24) is installed in the initial position by a spring (), which is fixed at one end to the bar (25a), and to the other end to the bar (25).

Subject invention

A rubber strap to the sewing machine for pulling; iantyToro and stitched edge of the product around the retractable rubber braid, made as a pair of pulling edge of the product with a band of corrugated rollers, of which the upper is spring-loaded, and the lower one is equipped with a lever drive from the main shaft of the machine roller clutch freewheeling, so that, in order to mechanize the bending of the edge of the product without additional bending, the device is equipped with a knife switch installed in front of the push button of the machine, bending the edge of the product around the lever arm, which is movable from the side of the net, serves as a guide for the rubber braid sewn into the curved edge of the product.
