Abstract
A dunnage system for processing material into dunnage is herein described. A converting station of the system can include a drum having a drum surface first and second axial sides and guides protruding adjacent the drum surface on the first and second axial sides associated with the drum to rotate with the drum surface. A supply gripping member can be provided to grip a supply roll, and can include a rotatable base. A pivotal blade can be used to cut the dunnage.
Claims27
A dunnage system for converting sheet material, comprising:
- a converting station that includes:
- a drum having a drum surface that has first and second axial sides;
- first and second guides protruding adjacent to and extending radially from the drum surface on the first and second axial sides, the first guide associated with the drum to rotate with the drum surface, and the first and second guides being configured for guiding the sheet material onto the drum surface laterally between the axial sides, wherein at least one of the guides is convexly dished with respect to the drum surface;
- a driving mechanism associated with the drum for rotating the drum;
- and
- a roller biased against the drum between the guides to grip the sheet material against the drum for pulling and converting the sheet material to provide dunnage material;
- and
- a cutting station disposed downstream of the converting station and configured for cutting lengths of the dunnage material.

- and
- a cutting station disposed downstream of the converting station and configured for cutting lengths of the dunnage material.
