ABSTRACT:
A yarn winding apparatus and thread-up process are disclosed wherein a yarn bobbin is supported between rotatable clamping plates, and wherein at least one of the clamping places has an annular groove which defines a pair of laterally spaced rims. The rim which is adjacent the bobbin includes a yarn drop slot, a yarn catching slot having a forwardly directed nose, and a cutting blade is mounted in the groove behind the yarn catching slot. To effect thread-up, the advancing yarn is guided into the drop slot and thus into the groove, and it is then guided axially toward the bobbin so as to cause it to be looped about the nose of the yarn catching slot. The segment of the yarn remaining in the groove is then severed by the cutting blade.
