Filed:

Dec 28, 1973

Appl. No.:

5/429283

Inventors:

Donald J. Stuart - Park Ridge IL

Assignee:

Midland Engineering and Machine Co. - Rosemont IL

International Classification:

H01f 4112

US Classification:

242 708

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.

International Classification:

B65C 302

US Classification:

156366

Abstract:

A taping machine for applying a protective wrapping to small parts, particularly electronic parts such as capacitors, having a longitudinal axis. Permanently adhesive tape is fed from a supply roll onto a forwardly inclined table at the front of the machine. Below the front lip of the table are a pair of horizontally extending rollers vertically aligned with one another. Interposed between the lip of the table and the rollers is a reciprocated cutter blade. A third roller mounted upon a swingable arm is bodily movable in triangular relation with respect to the pair of rollers. The end of the tape extends to the lip of the table, sticky side up, so that a part may be manually pressed adheringly to the tape in a transversely extending direction. Interposed between the roll of tape and the table is a swingably mounted knurled roller engaging the sticky side of the tape and about which the tape is looped. A hand wheel swings the roller rearwardly for pre-stripping a length of tape and then swings the roller forwardly to feed the length of tape across the table so that the part adhering to the tape drops over the lip of the table and into a centered position in front of the pair of rollers.

International Classification:

B32B 3100

US Classification:

156446

Abstract:

A machine for taping coils wound upon bobbins which includes an indexable turret wheel mounting a plurality of peripherally spaced mandrels dimensioned for slidable reception of the bobbins of a succession of coils, the turret traversing a loading station, a tape wrapping station, a wiping station and an unloading station. A tape applicator member at the wrapping station supports the leading end of the tape, the applicator being shiftable from a reference position to a pressing position in which the leading end of the tape is pressed against the side of the coil. Drive spindles are clutched to the mandrels in the wrapping and wiping stations for wrapping and wiping the tape. Fluid actuators having rack and pinion connections serve to index the turret wheel, shift the tape applicator, and rotate the coil in the wrapping and wiping stations. The phase position of each coil bobbin loaded on a mandrel in the loading station is preserved throughout the cycle to permit registered imprinting and the performance of other functions requiring accurate bobbin register.
