Automatic wrapper for bread loaves - has conveyor to side of roll of sheet with cutting and welding gear on pivoted arm

摘要

The automatic wrapper is for single items such as loaves, using a single sheet of plastics material. A conveyor (2) brings the bread (3) against the wrapping sheet (7), with the load length parallel to sheet unrolling. A roller (6) divides the sheet and there is an arm (9) pivoted around an axis parallel to sheet unrolling. Another roller drives the sheet with intermittent movement and there is a station (11) to weld and cut the sheet. The two latter are on the pivoted arm end. This equipment is duplicated (13); to cut and weld perpendicular to the first set.
