THREAD BRAKE AND TEXTILE MACHINES AND THREAD FEED DEVICES EQUIPPED THEREWITH

摘要

A yarn break is characterized by reducing contamination, constituting a spring mechanism, being connected with an assembled section of a bearing pin set a preloaded mechanism for adjusting break force and being unconnected with a bearing section traveling a break unit. A knitting machine and a yarn feeding device are equipped with the yarn break. A yarn break comprises: a fixing device(17); an axis(22) of the fixing device; an assembled section set in the fixing device; a bearing pin(25) containing a bearing section(26) set after the assembled section in an axial direction and protruded out the fixing device; a first break unit which is set and moved on the axis of the bearing section, being opposite to the fixing device and being adjacent to the fixing device; a second break unit which is set and moved on the axis of the bearing section, being opposite to the first break unit and being adjacent to the first break unit; a preloaded unit containing a tension unit(39) adhered on a spring(29) and the bearing section and adjusting break force; and an adjusting and protecting device(20) receiving the assembled section and the spring. The assembled section is preloaded by the spring. A preloaded mechanism is capable of moving on the axis in the fixing device.
