ABSTRACT:
Apparatus for folding, bonding and severing a longitudinally extending web, comprising a rotatable disc having a plurality of circumferentially spaced-apart, radially extending protrusions at its periphery, means for rotating the disc, means for feeding the longitudinally extending web onto the disc during rotation thereof, so that outer extremities of the protrusions contact the web at its medial region to cause folding of the web so that its sides overlap one another between the protrusions, means for bonding the folded web at its overlapping sides between adjacent protrusions during rotation of the disc, and means for severing the folded web at its overlapping sides between adjacent protrusions during rotation of the disc. Also disclosed is a corresponding method wherein the longitudinally extending web is folded, bonded and severed. The system of the present invention facilitate carrying out of the folding, bonding and severing operations in a single work station and is suitable for use in commercial high-speed operations.
