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 open 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 provides a simple means to vary and control flexible product width without introducing a multiplicity of moving parts, and discloses means to enhance separation of individual products during transfer while increasing overall production rates.
