ABSTRACT:
A hand operated taping machine for winding protective tape upon a wire coil used in a relay, solenoid or the like in which a coil is chucked upon a spindle. Tape with a tacky adhesive is fed via a series of rollers terminating in a leading end which is supported upon an applicator pad adjacent the coil. The pad is manually pressed into engagement with the coil to tack the leading end. The spindle is rotated via a main drive shaft by a manual crank. A cutter blade is provided adjacent the pad. A first cam on the main drive shaft lowers the cutter blade and pad permitting the tape, under tension, to be manually severed below the level of the coil to form a tail and to position a new leading end on the pad. A second cam on the main drive shaft operates a wiper to wipe the tail down upon the coil, withdrawing the wiper as the pad is restored to its initial tape applying position in readiness for a new cycle. Means are provided for creating slack in the run of tape incident to this return movement to insure that when the new leading end is tacked to a subsequent coil the coil will be able to rotate sufficiently to create purchase, so that the tape will not pull free of the coil, before normal winding tension is reestablished. A gear shift between the main drive shaft and the spindle determines the number of layers of tape which are applied in a single revolution of the main drive shaft.
