Abstract

A tape application system using a tape with low tensile strength and dispenser wherein the dispenser, in lieu of cutting means for the tape has a brake permitting the operator to brake the applicating roller and apply a tensile force to the tape between the applicating roller and the applied tape surface fracturing the tape to sever the applied tape from the tape on the roll.

Claims

1. AN ADHESIVE APPLICATION SYSTEM COMPRISING A ROOL OF ADHESIVE TAPE COMPOSITION HAVING A THIN FLEXIBLE FRANGIBLE BASE LAYER COATED ON ONE SURFACE WITH A FIRST PRESSURE-SENSITIVE ADHESIVE COMPOSITION, AND COATED ON THE OPPOSITE SURFACE WITH A SECOND PRESSURE-SENSITIVE ADHESIVE COMPOSITION, WHICH ADHESIVE COMPOSITIONS ARE CHEMICALLY DIFFERENT AND PHYSICALLY IMCOMPATIBLE PERMITTING THEM TO BE WOUND TOGETHER IN SAID ROLL AND LATER SEPARATED FROM EACH OTHER, AND A DISPENSER COMPRISING A FRAME, SAID FRAME HAVING MEANS FOR ROTATABLY SUPPORTING SAID ROLL OF TAPE, AN APPLICATING ROLLER SUPPORTED BY SAID FRAME FOR ROTATION ON AN AXIS PARALLEL TO THE AXIS OF SAID ROLL OF TAPE AND ROTATABLE WITH RESPECT TO SAID FRAME, SAID ROLLER HAVING A ROUGHENED SURFACE TO CONTACT ONE SURFACE OF SAID TAPE TO DRAW SAID TAPE FROM SAID ROLL, AND BRAKE MEANS ON SAID DISPENSER ENGAGEABLE WITH SAID APPLOCATING ROLLER FOR STOPPING ROTATION OF SAID APPLICATING ROLLER TO PERMIT FRACTURE OF THE TAPE BY A PULLING FORCE IN A DIRECTION AWAY FROM THE APPLIED TAPE.

2. An adhesive applicating system according to cLaim 1 wherein said applicating roller has a high friction surface formed on one axial end and said brake means includes a surface engageable with said high friction surface to stop said roller.

3. An adhesive applicating system according to claim 1 wherein said applicating roller has lugs formed on one axial end and said brake means comprises a lever supported on and resiliently movable relative to said frame, and a plurality of teeth on said lever engageable with said lugs upon movement of said lever toward said roller.

4. An adhesive applicating system according to claim 1 wherein said frame comprises a pair of mating molded pieces and said brake means comprises a lever molded integrally with one of said pieces and joined to said one of said pieces near the axis of said applicating roller and extending axially and radially beyond the roughened surface of said roller.

5. An adhesive applicating system according to claim 1 wherein said roller is formed of segments and a stripping blade is positioned between the segments to separate the tape from the roller surface.

6. An adhesive applicating system according to claim 5 wherein said applicating roller has a high friction surface formed on one axial end segment and said brake means includes a surface engageable with said high friction surface to stop said roller.

7. An adhesive applicating system according to claim 5 wherein said applicating roller has lugs formed on one axial end segment and said brake means comprises a lever supported on and resiliently movable relative to said frame, and a plurality of teeth on said lever engageable with said lugs upon movement of said lever toward said roller.
