Abstract
Abstract In a tape dispensing apparatus by which predetermined lengths of tape material are dispensed from a reel by co-operating rotatable feed and pressure rollers the feed roller is rotatable by a motor through a spindle driven by the motor. An electric signal producing means is operated by the spindle following a predetermined angle of rotation of the spindle and then sends an electric signal to a selection device which in response to the signal applies the brake to stop rotation of the spindle thus determining the length of tape drawn from the reel by the feed and pressure rollers.

Claim 1
Independent Claim
161 words
TApe dispensing apparatus for dispensing predetermined lengths of tape material from a reel thereof, comprising a drive motor; a driven spindle coupled to the drive motor; a tape material feed roll mounted on the driven spindle; a brake arranged to act on the driven spindle; electric signal producing means operated by the driven spindle and adapted to provide an electric signal indicative of a predetermined angle of rotation of the driven spindle; and selection means responsive to the electric signal produced by the electric signal producing means to effect application of the brake to halt rotation of the driven spindle after a predetermined angular rotation of the driven spindle in which the electric signal producing means comprises an electric pulse signal producing means in the form of a contact breaker arrangement comprising a counter cam mounted on the driven spindle and a co-operating contact breaker arm arranged to open and close a pair of contacts to provide an electric pulse signal.
