Abstract: A method is provided for removing mandrels from successive rolls of convolutely wound web material. In one aspect, a roll of web convolutely wound around a mandrel is moved to a position in which the mandrel is aligned with a clasp with the clasp spaced apart from the mandrel. The clasp is then moved along a path toward the roll. Movement of the clasp toward the roll is stopped only when the clasp is in a position to engage the mandrel. The mandrel is engaged with the clasp. The clasp and the mandrel are moved away from the roll to withdraw the mandrel from the roll. The mandrel is released from the clasp when the mandrel is removed from the roll. The mandrel is removed from the path of the clasp. The steps are repeated for a subsequent roll.
