Description

This invention relates to a weaving machine for cutting weft threads. The existing devices (scissors) are all complex in structure, wear out quickly, disassemble and break. Work with each punch of the batana, scissors often port t reed and batana In addition, all existing scissor systems are mounted on the right spinning rod, due to which the spinning rod becomes more structurally complex, often loosened and not strong enough.

To eliminate these drawbacks, a device is proposed that acts only when the weft spool is changed; the rest of the time the fixture does not work and, therefore, does not wear out. A distinctive feature of the proposed adaptation is that it is made in the form of a wedge-shaped knife mounted on a bat’s baton, which has one edge

is the blade for cutting the thread, and the second is the pick for receiving the thread when changing the spool, the blade and the pick are inclined at an angle from the vertical line towards the edge of the fabric.

The drawing shows the device installed on the bat (side view). The device consists of a knife / made of hardened steel. One edge of the knife is a blade and is tilted so that the thread is cut, slipping along the blade. The knife is fastened with a bolt 3 on the square 2 to the batana 5 from the side of the right rod. In operation, the knife moves with the bat near the right reel about 2-3 mm from it. The end of the knife is set 3-5 mm above the blade. When the batana is in the rear position, the end of the knife should be 2-4 mm from the edge of the edge of the fabric 6.

When the spool change occurs, the sacrificial scissors cut the thread 7 from the spool and keep

her, and the knife, leaving with a bat, passes under this end of the thread. The thread, the slippery along the second edge of the knife, which forms its edge, falls on its blade and, with the batana, is cut in the front position at the edge of the edge. With the next turn, the end of the weft thread of the newly inserted spool, which goes from the spool changer, is cut off with a turn of the batan. After trimming, the knife is stopped until the next change of the spool.

Subject invention

A weaving machine for cutting weft yarns, characterized in that it is made in the form of a wedge-shaped knife mounted on a bat’s baton, in which one edge is a blade for cutting the thread and the second is a picker for receiving the thread when the spool is changed, the blade and the pick is inclined at an angle from the vertical line towards the edge of the fabric.
