ABSTRACT:
The machine of the present invention fabricates briefs having an openable front panel from two continuous half width webs. The first and second web paths are transversely spaced. It includes feeding and folding devices to add a V-folded reinforcing strip along the edge of one web. Feeder and tensioning devices are included for elastomeric strands that shirr the briefs and to add a re-closable tape across the front panel opening. One of the webs is printed with adhesive at spaced intervals to bond portions of the two overlapped webs in central areas of overlap that become the rear panel after the web is cut into segments and transversely folded. The machine attaches components of the brief and cuts leg apertures and side flaps on each web while the advancing overlapped webs are continuous. After transfer to a rotary drum, the web is severed into overlapped segments which are then cross folded by drum elements before the flaps extending from each side are folded over to secure the back panel to the openable front panel. Another embodiment severs the web into segments before being transferred to the drum for final cross folding into front-rear panels and flap foldover to connect the panels together.
