Abstract

A machine is disclosed for shrink wrapping a load of a given size, the machine including a supply conveyor for supplying the load to a wrapping zone, and a wrap conveyor disposed in the wrapping zone, the wrap conveyor receiving the load from the supply conveyor. A film supply supplies a film to the wrapping zone. The film supply includes a cutting mechanism having a position selectively fixed within a cutting zone. A wrap guide is disposed in the wrapping zone for guiding film received from the film supply in a wrap path proximate the wrap conveyor so as to place the film on the load. The wrap guide includes a wrapping bar that moves along the wrap path so as to move the film at a speed varying between a maximum speed and a minimum speed. The cutting mechanism cuts the film when the film speed is below the maximum speed. A heat supply shrinks the film so as to shrink wrap the load. Related machines, cutting assemblies, and methods are disclosed.
