ABSTRACT:
An apparatus is disclosed for splicing the trailing end of an expiring web of an old stock roll to the leading web end of a new stock roll. The new stock roll is provided with a splicing tape for initially releasably attaching the leading end of the new stock roll to its outer web convolution. A plurality of sensors are provided for positioning the new stock roll and splicing tape in a precise presplicing position prior to the splicing operation. During the splicing operation, a web guiding and severing mechanism guides the expiring web into engagement with the new stock roll, severs the expiring web, and splices the trailing end of the expiring web to the splicing tape on the leading end of the new stock roll.
