Expired paper rolls are removed from one unwinding station in a paper processing plant by engaging them with a gripper and transferring them onto a conveyor which can be operated to move expired rolls axially. Each expired roll is rotated about its own axis before the conveyor is set in motion so that the projecting remnant of web is convoluted around the expired roll before the latter begins to move axially. The one unwinding station is adjacent a second unwinding station which receives a fresh roll from a conveyance while the preceding roll is caused to pay out its web at the one station. The supporting arms for the roll at the one station are pivotable between the two stations so that a partly expired fresh roll can be shifted from the second station to the one station prior to conversion of such roll into an expired roll.
Apparatus for removing expired paper rolls from an unwinding station of a paper processing machine wherein a remnant of the web on an expired roll is severed from the already unwound length of the web and wherein the remnant of the web projects or tends to project from the roll subsequent to severing of the remnant from the already unwound length of the web, comprising conveyor means defining a predetermined path for axial movement of expired rolls;
