Abstract:

The prior art apparatus to wind vertically running yarn was a vertical spindle with a pulley mounted on a driven shaft, a stationary yarn wheel guide, an upper vertically movable yarn guide wheel, a lower vertically movable yarn guide wheel, a double track cam vertically mounted with a driven pulley and shaft, an upper cam follower and shoe, a lower cam follower and shoe, cam housing having a vertical slot, a motor having both a spindle drive pulley and a cam drive pulley mounted on a drive shaft, a belt to drive the spindle from the motor and a belt to drive the cam from the motor. The motor would drive the vertical spindle and the cam by the connection of the driven pulleys to the motor drive pulleys with belts. The vertically movable yarn guide wheels were connected to their respective cam followers and the cam followers were both driven by this one double track cam to oscillate vertically in the cam housing slot. In this manner, the upper vertically movable yarn guide wheel oscillates in the upper half of the housing slot and the lower vertically movable guide wheel oscillates nearly the full length of the housing slot and for the full traverse of the winding yarn.
