ABSTRACT:
Selectively reconfigurable shrink-wrap machine (30) for use with a loading device (34) for individually wrapping products (58) sequentially with shrink-wrap material (92) as delivered in sequence to the machine. It includes a sensor (62) sensing product position on the loading device. Shrink-wrap material is delivered from a roll at a wrapping station (40). A first conveyor (42) carries wrapped products between the wrapping station and a film sealing and cutting apparatus (44). First conveyor delivers products sequentially in synchronized velocity with the loading device in response to sensor signals. Film sealing and cutting apparatus has upper and lower heads (156, 164), at least one of which is driven into and out of engagement with the other between adjacent wrapped products received by the first conveyor for effecting a sealed cut between them. Heads are each maintained at a fixed angle of orientation. A second conveyor (43) receives wrapped products sequentially from the sealing and cutting apparatus. A microprocessor-driven touch screen (48) and a method controls the shrink-wrap machine and is described.
