Abstract
A device for removing, from a reel of strip material, an adhesive tape secured to a peripheral surface portion of the reel via thermoplastic adhesive material; which device comprises a pair of rollers supporting the reel; one of the rollers being a drive roller for rotating the reel about its axis; at least one heating element located close to the peripheral surface of the reel and designed to substantially contact the tape; and the other roller having vacuum openings for removing the tape from the peripheral surface of the reel subsequent to the adhesive material being plasticized by the heating element.
Claims13
A device for removing adhesive tape from a roll of wound strip material, the adhesive tape being affixed to a portion of a peripheral surface of the roll by thermoplastic adhesive material, the device comprising:
- support means for the roll, the roll being mounted on said support means to be rotatable about an axis;
- drive means for rotating the roll about said axis in a strip material take-up direction in which the strip material is taken up onto the roll;
- at least one fixed heating element close to said peripheral surface;
- and
- adhesive tape removing means arranged at a first location in relation to the roll, and adapted to remove said tape from said peripheral surface after the adhesive material is plasticized by heat from the heating element and with the reel rotating in said strip material take up direction.
A method of removing an adhesive tape from a roll of wound strip material, with the adhesive tape being affixed to a portion of a peripheral surface of the roll by thermoplastic adhesive material, comprising:
- supporting the roll on a supporting means so that the roll is rotatable about an axis;
- rotating the roll about said axis in a strip material take-up direction in which the strip material is taken up on the roll;
- heating the adhesive tape, by means of a fixed heating element substantially contacting the said peripheral surface, until the adhesive material is plasticized;
- and
- with the reel rotating said strip material take-up direction, removing the heated adhesive tape from the roll peripheral surface by a removing means arranged at a fixed location relative to the roll.
