METHOD AND APPARATUS FOR PRODUCING CORELESS ROLLS OF PAPER
A machine forms a roll of convolutely wound web material. The machine includes a winding apparatus configured to receive a mandrel and the web material and wind the web material around the mandrel. A pulling device pulls the mandrel longitudinally to remove the mandrel from the roll after forming the roll. The machine further includes a restraint that engages the peripheral surface of the roll when the mandrel is pulled longitudinally to remove the mandrel from the roll. A method is also provided. In one aspect of the method, a web material is wound around a mandrel to form a roll of convolutely wound web material. The mandrel is pulled longitudinally after the step of winding the web material around the mandrel. The periphery of the roll is restrained from moving axially when the mandrel is pulled longitudinal. The mandrel is then removed from the roll.
