Description

Known devices for pushing nptey into shuttles, vertically mounted in the head of the shuttle, made in the form of a shaped plate with bends, guides and hold back the thread, as well as a method of threading the thread to bring it to the level of the top of the shuttle. However, such devices have the disadvantage that they do not exclude the possibility of stitching the weft yarn and touching it over the weft fork.

The described fixture differs from the known ones in that the threading of the thread in the shuttle is carried out in it in the absence of a lateral incision. This simplifies the design, eliminates the possibility of burning the thread and reduces the incidence of grasping it at the weft fork.

FIG. 1 shows a schematic weaving shuttle with a device in a longitudinal section; in fig. 2- shuttle, plan view; in fig. 3 device side view; in fig. 4- type of adaptation in two projections; in fig. 5- second variant of the device, side view; in fig. 6 is a second variant of adaptation in two projections.

The device is made in the form of a shaped plate / with a small box for guiding the thread, made in the form of an open ring 2, bent to the side of the shuttle hook. The ring is formed by a bend in the horizontal plane of the upper edge of the plate, installed vertically in the head of the shuttle. The shank of the plate is fixed in the longitudinal groove of the shuttle head.

The weft thread is made as follows. After charging into the shuttle 5 spools, 4 shuttles are taken in the left hand, and the weft thread 5 is pressed with the right hand. 5. It is directed along the upper side of the shuttle by its toe. At this moment, the thread enters the recess of the shuttle and at the same time in the center of the thread of the device for threading the thread. When you turn your hand, the thread automatically enters an open ring 2.

For shuttles, in which the device is located on the left side of the shuttle, the thread is turned in the opposite direction, i.e., with the left hand.

A threading device for weaving shuttles, made in the form of a shaped plate with a groove for guiding the thread, which is different in that in order to bring the thread to the level of the top of the shuttle

Subject invention

The filament for the thread is {in the form of an open ring, bent to the side of the shuttle hook and formed by a bend in the horizontal plane of the upper edge of the plate vertically installed in the shuttle head, fixed in the longitudinal groove of the shuttle head.
