Patent GB-1041157-A (GB)
Title: Yarn-handling devices
Inventor: BUNTING WILLIAM WALLAR
IPC: B65H54/71
Filed: 1965-04-08
Abstract: A pneumatically operated handtool selectively entrains, tensions, severs and redirects the severed end of, a running yarn in preparation for its transfer e.g. to (another) wind-up mechanism, without significant loss of tension.  The tool comprises an air inlet tube forming, between itself and the inlet end of an extended yarn outlet tube coaxial therewith, an annular orifice and a converging-diverging nozzle.  When a normally retracted, air-piston operated push-rod is rapidly advanced, its flattened and bifurcated end engages the yarn, which has been guided into (and is tensioned by) a zone of turbulent air in the vicinity of the inlet tube, and pushes the yarn through a central bore in the nozzle nozzle and into the outlet tube where it is entrained and advanced under tension by a high velocity e.g. supersonic, air stream flowing through the nozzle and along the outlet tube: in addition, the operating piston either engages a slidable push-pin which drives a movable blade across a stationary blade to sever and free the yarn end, Fig. 4 (not shown) or forces a pin to break the yarn by frictional snubbing; Fig. 15 (not shown).  The piston and rod then retract to their normal position but the yarn continues to run through the outlet tube under tension.  The push-rod may be pneumatically held in the normal position against an advancing spring, Fig. 4, (not shown) or it may be spring retracted and advanced pneumatically, Fig. 15; (not shown) its operation is controlled by a manually operated slide-valve.
