Abstract:
Devices for deforming tape backings and which thereby impart a curl to adhesive tapes are described. One type of device comprises means whereby a tape backing is deformed as the tape is bent back upon itself at an angle as it detaches from a roller to which it has been adhered. An alternative type of device comprises means whereby a tape backing is deformed as the tape is deformed into grooves on a fluted roller.
