ABSTRACT:
Web splicing method and apparatus for use in a web supply line are disclosed in which the following ends of first and second webs respectively wound around first and second old rolls are respectively spliced to the leading ends of first and second webs wound around first and second new rolls to thereby unwind the first and second spliced webs simultaneously and successively and the first and second spliced webs are superposed on each other at a predetermined meeting point before they are supplied. In the web splicing method and apparatus, the timing of start of splicing of the second web is controlled in accordance with the time of completion of the splicing of the first web so that the relative positions of the respective spliced portions of the first and second webs can be shifted from each other by a preset distance or the relative positions thereof can be made to coincide with each other.
