Yarn traverse mechanism, especially for an automatic pirn winding machine and of the kind comprising a carriage, means for progressively advancing the carriage, a yarn guide pivotally mounted on the carriage, oscillationimparting means mounted on the carriage for oscillating the yarn guide to provide a normal traverse therefor, is characterized by further oscillation-imparting means operably associable with the yarn guide adapted to over-ride the normal traverse oscillation and to impart a " bunch building " oscillation for the commencement of the winding of a pirn. As shown, a traverse carriage 13 carrying a multiple face cam 16 for selectively traversing, by oscillation, a spring biased yarn guide 24 of wire, is reciprocated and also progressively moved along rods 11,12 by mechanism in the headstock 10 and by a screw 17, the cam 16 being rotated by a square-sectioned shaft 15 which also carries a bunch-building cam 42. After the operations of doffing and donning, at the commencement of a new wind, the bunch-building hook 30 attached to a shaft 29 moves to restrain the wire guide 24 which flexes to allow the reciprocating of the shaft 29, through the hook 30, to build a bunch on the pirn tube on the spindle 10a. The shaft 29 is reciprocated by the cam 42 through a stud 41, shaft 39, bell-crank 43, link 69, lever 66 and collar 31. The pawl 44 on the crank 43, during its oscillation, turns the ratchet wheel 50 until a notch 53 therein allows a holding pawl 54 to move therein thus allowing a spring-urged arm 58 to pivot and move the peg 32 to turn the shaft 29 and remove hook 30 from the yarn guide 24 to allow normal traversing to begin. The amount of rotation of the ratchet wheel 50 is adjustable by means of a notched wheel 47 and holding pawl 49, the wheels 47,50 having upstanding studs 48,51 which cooperate for this purpose.
