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. |
