SU86838A1 - Adaptation to the loom for the manufacture of terry towels - Google Patents

Description

The special feature of the described device is that it uses a disc cam rotating from a diaphragm and controlling through a system of levers and turning on and off the terry weaving and undersize device, and mounted on the same axis with it a slotted disk serving for switching on and off the mechanisms of the bo and weft fork, the mechanism for rolling the fabric.

FIG. 1 shows the device in vertical section (front view of the machine) and in FIG. 2 - the same (side view of the machine).

The device consists of a disk cam /, made in the form of a cylindrical toothed jaws, one turn of which produces ONE towel. The slotted disk 2 with the depressions 5 along the periphery interacting with the cam 4 mounted on one of the arms of the lever 6 slides along the surface of the slotted disk 2 at the time of running the surface and instantly lowered into the deepening of the disk under the action of a spring 5, facilitating the lifting of the opposite arm of the lever 6, which at the end carries the locking mechanism 7, is spring-loaded 8, controls the loop-forming mechanism on the fabric, which automatically switches the work of the machine from the surface to the terry weave and reverse about.

On the lever arm 5. vertically reinforced vertical lever 9, which interacts with dogs of an underdeveloped device, disconnecting them from work to relieve tension on the warp threads when forming the first loop when changing from iron to terry interlacing.

For rolling the fabric, a mechanism, made in the form of a 70 Gaul chain, transmitting the movement from the machine crankshaft to the dial-up mechanism using a clutch 11, was used in the fixture.

No. 86838-2 -

switching the driving gear 12 on and off via the forked lever 13.

The clutch is strengthened by a sliding key on the protrusive vals, the bo gear mechanism is turned on and off by axial movement of the combat wheel 14 along the spindle 15 extended for this.

To shut out the weft fork 16 when rolling the cloth using the hammer U7 of the fork 16 of the locking bar 18, which interacts with the slotted disk 2, with the help of a double-arm lever 19 is turned off.

Subject invention

Claims (4)

1. An attachment to a loom for the manufacture of terry towels, which is excellent in that, in order to automatically switch the work of the machine from the terry weave to the plain and back, as well as rolling the fabric to form a fringe, it uses: a disc cam rotating from the dial mechanism and controlling through a system of levers and turning on and off the mechanisms of forming a terry weave and undersize device, and a slotted disk mounted on the same axis with the cam disk and serving to turn on and off Turn off the mechanisms of bo and weft fork. 2. Device according to claim I, characterized in that the mechanism for rolling the fabric is made in the form of a Gall chain, transmitting movement from the crankshaft of the machine to the dial mechanism, by means of a clutch, which turns the driving gear on and off of the Gall chain. 3. Device according to claim 1, characterized in that the mechanism is turned on and off by axial movement of the combat roller over the extended rod for this. 4. A device according to claim 1, characterized in that the rod of the fork fork is lifted by a thrust that interacts with the slotted disk and turns off the fork from work during the rolling of the fabric. 12 13 Fig.i / 6 Fig 2
