Claims
- 1. A yarn guide assembly adapted for use on a high speed winding machine or the like and which is adapted to traverse a running yarn along a predetermined yarn traverse stroke, and to selectively engage the traversing yarn and move the yarn beyond the normal yarn traverse stroke in order to facilitate the yarn transfer onto an empty bobbin or the like, and comprising
- yarn traversing means for traversing a running yarn along a predetermined yarn traverse stroke, said traversing means comprising a yarn guide which includes a plate-like member composed of a pair of outwardly extending flanks which are laterally separated to define a slot therebetween, with said slot including opposing edges, and with one of said edges of the slot including a recess adapted to substantially restrain a yarn from sliding along such edge,
- auxiliary yarn guide means for selectively removing the running yarn from said yarn traversing means and moving the running yarn laterally beyond said predetermined traverse stroke, said auxiliary yarn guide means comprising yarn catching means which includes a yarn receiving gap and an inclined edge surface on one side of said gap, with the inclined edge surface being positioned so as to oppose said one edge of said slot which includes said recess, and means for selectively moving said yarn catching means along a path of movement wherein the yarn catching means moves into said predetermined traverse stroke, then laterally beyond said traverse stroke,
- whereby movement of the yarn catching means into said predetermined traverse stroke results in the running yarn being moved along the inclined surface and into said gap by
- said yarn traversing means with said recess in said one edge of said slot acting to retain the yarn in said slot until the yarn at least reaches said gap, and so that the yarn may then be withdrawn from the yarn traversing means and moved by said yarn catching means laterally beyond said predetermined traverse stroke.
- 2. The yarn guide assembly as defined in claim 1 wherein each of said flanks of said traversing yarn guide includes an outer edge, with the outer edges being oppositely inclined toward a point adjacent the opening of said slot to thereby facilitate the capture of the yarn in said slot.
- 3. The yarn guide assembly as defined in claim 2 wherein the flank of said traversing yarn guide which includes said recess extends outwardly beyond the other flank.
- 4. The yarn guide assembly as defined in claim 3 wherein said auxiliary yarn guide means further comprises a support member, and means mounting said support member so as to permit selective movement in opposite directions along a linear path of travel which is parallel to the yarn traverse stroke, and wherein said yarn catching means comprises a guide finger fixed to said support member and extending transversely therefrom in a direction so as to be adapted to intersect the plane of the traversing yarn stroke, a guide plate mounted to said support member for relative movement in a direction parallel to said guide finger and between an extended position and a withdrawn position, and with said guide plate being located immediately adjacent said guide finger so as to define said yarn receiving gap therebetween, and with said inclined edge surface forming the forward edge of said guide plate, and means for selectively moving said guide finger between said extended and withdrawn positions.
