Apparatus for making and manipulating sheet-like paper, plastic or metallic blanks in a packing machine has a pivotable conveyor with a gripper which pulls the leader of a running web across the path of successive mandrels or cigarette packs on an indexible turret whereby the gripper overcomes the resistance of a mechanical or pneumatic clamping device which holds the leader of the running web in a position in which the leader can be engaged by the gripper when the conveyor completes a return stroke. The running web is severed by a pair of knives which are installed between the clamping device and the gripper and are caused to cut the web when the gripper reaches an end position in which a sufficient length of the running web is moved across the path of an oncoming mandrel or cigarette pack. A fresh web is threaded into the apparatus while the running web is being converted into a succession of blanks, and the leader of the fresh web is held at a preselected locus so that it can be moved into the range of the gripper as soon as the supply of running web is nearly exhausted. The apparatus then ceases to advance the running web and starts to advance the fresh web from the respective bobbin toward the locus where the leader of the fresh web can be engaged by the gripper. The leader of the expired web is moved out of the way not later than when the leader of the fresh web moves into the range of the gripper.
