1. A device for applying a strip of double-sided pressure sensitive adhesive tape to a surface, said device comprising a supporting frame, a rotatable supply roll of composite tape consisting of a layer of double-sided adhesive tape adhered to a strippable backing liner;
- a rotatable transfer roller having a surface with a poor affinity for said adhesive tape;
a rotatable rubbery pressure roller positioned to receive said composite tape from said supply roll and press a side with the double-sided adhesive tape against said transfer roller;
a rotatable windup roller to receive said backing liner;
means for coordinating the rotation of said supply roll with the rotation of said windup roller; and
stop means for selectively permitting or preventing the rotation of said supply roll.

8. A device for applying a strip of double-sided pressure-sensitive tape to a surface;
- said device comprising a supporting frame to which are attached four rotatable rollers for handling and applying said tape, said rollers including a first roller for containing a supply of composite tape including a nonadhesive backing liner carrying on one side thereof a strip of double-sided pressure-sensitive adhesive tape, a second roller for receiving said composite tape from said first roller and pressing said adhesive tape strip against a third roller, said third roller having a poor affinity for said adhesive tape and being adapted to receive said pressure-sensitive adhesive strip disconnected from said backing liner and pressing said adhesive strip onto said surface, and a fourth roller to receive and windup said backing liner separated from said adhesive tape at the contact between said second and third rollers, said first and said fourth rollers being operatively joined by gear means to rotate simultaneously, and correspondingly; and
a selective locking and unlocking means to prevent and permit, respectively, the rotation of said first roller. - View Dependent Claims (9, 10, 11, 12, 20)
