DEVICE FOR FEEDING WRAPPERS IN A PACKAGING MACHINE

摘要

In a packaging machine there is provided a feeding device which advances a wrapper sheet of indefinite length transversely through a folding channel and introduces the lower, leading edge of the wrapper sheet into a slot provided in the floor of the folding channel. The feeding device has a complemental feeding assembly which provides the wrapper sheet with provisional longitudinal corrugations for rendering it sufficiently stiff to ensure its easy introduction into the slot. A cutter severs the wrapper portion positioned in the folding channel and a pusher moves an article along the folding channel against the wrapper to fold the latter about the leading face of the article.
