Yarn-supplying apparatus in knitting machine

Abstract

A yarn-supplying apparatus and a yarn-supplying apparatus system are disclosed. The yarn-supplying apparatus is capable of preventing undesired movement of a yarn guide arm and actuating a movable blade for cutting a yarn end in coordination with the movement of a yarn guide member. The yarn-supplying apparatus system is capable of circulatingly moving selection means, such as a single actuator, between the yarn-supplying apparatuses. A yarn-supplying apparatus in a knitting machine is characterized in that the apparatus comprises yarn guide members, an intervention member such as a selector, and a lock mechanism capable of, when one of the yarn guide members is advanced in the locus of a yarn guide arm-moving cam by selection means such as an actuator through the intervention member, fixing a condition where the yarn guide member is being advanced in the locus of the yarn guide arm-moving cam.

Description

technical field [0001] The invention relates to a yarn feeder for a knitting machine (a yarn feeding mechanism for a knitting machine) and a yarn feeding system. Background technique [0002] Traditional circular knitting machines have multiple yarn feeders mounted on the edge of a cylinder. According to the design of the knitted fabric pattern, a large number of yarns of different colors or qualities are selectively fed by each yarn feeder, each yarn feeder has a number of yarn guide rods respectively, with holes in the tips . Each yarn guide bar of the yarn feeder can be selectively operated to guide a selected yarn into the knitting position or out of the weaving position. As described in Background Patent Documents 1, 2, 3, the yarn guide lever is operated by a yarn selection device, for example, an actuator or an electromagnetic coil energized according to a signal from a storage device. Movements of the selection device, eg actuation, are transmitted directly or ind...

AI Technical Summary

Problems solved by technology

When the operation of moving the yarn guide rod to the position where its butt end can be engaged by the actuator and the control cam of the yarn guide rod and the operation of advancing the yarn guide rod to the yarn feeding position by the control cam of the yarn guide rod occurs even extremely Small mistakes may also cause the butt end of the yarn guide rod to fail to engage with the control cam of the yarn guide rod, or these components may cause damage to each other or other components due to mutual interference, causing downtime
