ABSTRACT:
A cover winding apparatus can wind and rewind a cover that is detachably attached to an opening of a container. A control apparatus is provided so that the roller member can be assured to stop at a different position on each winding cycle. A plurality of detecting sensors can define a stop position for the roller member and alternatively the control apparatus can be utilized to generate a different pulse number that can be applied to a stepper motor with a variable pulse number used for each operation of a winding cycle.
