Device for preparing a weft

Abstract

Abstract THE DEVICE INCLUDES A THREAD GUIDE FOR CONDUCTING A WEFT THREAD, WHICH HAS A THREAD OUTLET THROUGH WHICH THE THREAD EMERGES FROM THE THREAD GUIDE, AND WHICH IS MOVABLE TO CARRY THE THREAD OUTLET THROUGH A SUBSTANTIALLY ELLIPTICAL PATH. TWO THREAD CLAMPS FOR INTERMITTENTLY CLAMPING THE THREAD ARE PROVIDED AT TWO POINTS WHICH ARE CENTRALLY LOCATED ON THE TWO LONG SIDES OF SUCH ELLIPTICAL PATH. A PAIR OF SHOULDER ARE LOCATED IMMEDIATELY INSIDE THE TWO SHORT SIDES OF THE ELLIPTICAL PATH, AROUND WHICH THE THREAD IS WOUND AS THE THREAD OUTLET MOVES THROUGH THE ELLIPTICAL PATH. TWO HOOK MEMBERS ARE CYLICALLY MOVABLE, SUBSTANTIALLY 180* OUT OF PHASE WITH ONE ANOTHER, IN TWO PARALLEL PATHS THAT INTERSECT THE ELLIPTICAL PATH ON OPPOSITE SIDES OF ONE OF THE THREAD CLAMPS. EACH HOOK MEMBER ENGAGES THE THREAD SO AS TO DRAW A LOOP OF THE THREAD OUT OF THE ELLIPTICAL PATH. A CUTTER IS PROVIDED FOR SEVERING THE THREAD AT A POINT IN THE ELLIPTICAL PATH WHERE THE THREAD ENTERS THE OTHER THREAD CLAMP, AND A PAIR OF PUSHING NEEDLES ARE INTERMITTENTLY LONGITUDINALLY MOVABLE IN TWO PARALLEL PATHS THAT INTERSECT THE ELLIPTICAL PATH ON OPPOSITE SIDES OF THE OTHER THREAD CLAMP, FOR ENGAGING THE THREAD TO DELIVER IT TO A WEFT INSERTING DEVICE.
