<p>A device to remove bread from its wrapper so that the bread may be recycled. Wrapped bread moves on conveyor (11) between vertical guide plates (not shown). A horizontal rotating disc blade (12), the radius of which extends right across the bread, slices through the lower part of the loaf including slitting the front and sides of the wrapper. However, the rear face of the wrapper is not cut and on subsequent movement of the article the intact but open wrapper adheres to upper conveyor (14) due to vacuum from chamber (15) whilst the bread drops onto lower conveyor (16). A chute (17) supplied with air from duct (18) draws the wrapper away on release from the vacuum of belt (14). Alternatively a pair of horizontal disc blades may be used. These are mounted on arms which pivot from opposite sides of conveyor (11) and cooperate to cut the face of the wrapper and then their respective sides thereof - thus avoiding cutting the bread itself. Bandsaws may be used in place of cutting discs and vacuum may be used, instead of an air blast, to remove the wrappers.</p> |
