1. A method for tabbing a free end on a roll of sheet material comprises the steps of:
tabbing the free end of the roll of sheet material at a tabbing position, where a tabber carrying a joiner are both in initial positions away from the roll of sheet material, moving the tabber to a second position adjacent the roll of sheet material, moving the joiner into an engagement position where the joiner is engaged with the free end of the roll of sheet material, creating a tab with the joiner simultaneously mechanically entangling and heat welding the sheet material, and returning the tabber and joiner to the initial positions, and
doffing the tabbed roll of sheet material, and
repeating the foregoing steps.
