ABSTRACT:
Apparatus for dispensing web material from a coreless roll of such material includes a rotatable shaft having a helical-shaped projection on the outer surface thereof. The projection resists end-wise removal of the roll from the shaft as long as the shaft is free to rotate. A lock arrangement is provided to prevent rotation of the shaft after the roll has been substantially depleted so that end-wise removal of the roll can be manually accomplished.
