Tape dispenser and take-up reel for tape backing

摘要

This invention generally relates to a tape dispenser with automatic backing removal more particularly including a spindle rotatably mounted for receiving said supply of tape; a pinch roller set in tension having an adjustment to set the drag for the tape supply passing through the pinch rollers that convert a pull of the tape to a rotary motion; a take-up spindle for spooling the protective backing layer when separated from the tape; a set of drag washers to maintain an pre-set tension as the protective backing is spooled onto the take up spindle; a first gear responsive to the rotary motion of the pinch roller set and a second gear responsive to the motion of the first gear and axially attached to the take-up spindle for spooling the protective backing.

主权项

1. A dispensing apparatus for tape having a protective backing layer thereon comprises: a lower pinch roller having a pre-set rolling drag adjusted by one or more coaxial drag washers; and an upper pinch roller having one or more springs to set the nip force between the upper and lower pinch rollers, wherein when the tape interengages the nip of the pinched rollers, the lower pinch roller converts a linear motion of the tape to a rotary motion that turns a take-up spindle for spooling the protective backing layer; said rolling drag adjusted by one or more coaxial drag washers to maintain a preset rolling drag while the protective backing spools onto the take-up spindle.
