Tape Dispenser

Printed-circuit layout tape is conveniently applied by a hand-held dispenser.

In the design of printed-circuit boards, self-adhesive colored acetate or cellulose tape must be placed on layout sheets prior to color separation photography. Tape is supplied on a narrow reel and must be very accurately applied--a difficult hand operation. Conventional tape pens, such as the Brady Model TP-4, tend to obscure the tape at the point of contact, making accurate placement, especially at bends, difficult.

This tape dispenser includes a hollow casing through which the tape end is threaded-by sticking it to a loading stick. The tape reel is placed on a circular spring and held in position by retaining bumps. The spring is clipped to the casing. In operation, the casing may be held in one hand while the tape end is put in place with a knife point held in the other hand.
