Device for performance of tubular segments transported transversely in the production of bags.

摘要

This invention relates to a structure for guiding tubular blanks through a sack end forming station through which the tubular blanks are transversely conveyed on a path of travel, said structure comprising two plates, which are disposed on opposite sides of said path of travel, and guiding surfaces associated with said plates and defining adjacent to said path of travel a gap which has a width that is at least as large as the thickness of the tubular blank. At least one of said guiding surfaces is formed by a bar, which is associated with one of said plates and capable of a limited movement in the plane of said plate and is urged toward the other plate by springs.
