ABSTRACT:
An apparatus and method for making individual flexible web products whereby a web material is tucked outwardly from the surface of a product drum by fixed projections, severed and sealed, and provided to one or more transfer points. The products are there transferred to one or more transfer drums with corresponding indentations, which deliver the products to packing devices. An alternative embodiment provides multiple delivery points by using lateral-shifting transfer drums. The apparatus and method vary and control flexible product width introducing a multiplicity of moving parts, and enhance separation of individual products during transfer while increasing overall production rates.
