ABSTRACT:
Two lengths of discrete web materials are automatically joined by suitable alignment and positioning of their respective leading and trailing web edges. Transverse movement of such edges is automatically controlled so that longitudinal margins of such edges are aligned, also. Once a first roll of material is emptied and its trailing edge is joined with a leading edge of a new roll of material, support structure for the new roll is pivoted so that the new roll is physically moved into the support and drive position previously occupied by the old roll.
