ABSTRACT:
A film wrapping machine comprises a pair of diametrically opposed film roll mounting and dispensing carriage assemblies which are used to individually and sequentially dispense their wrapping films. Accordingly, if depletion or breakage occurs within the wrapping film being dispensed by a first one of the pair of film roll mounting and dispensing carriage assemblies, the second film roll mounting and dispensing carriage assembly can effectively be activated so as to dispense its wrapping film whereby the film wrapping operation can continue with a minimum amount of stoppage or downtime. The switch-over or change-over between the first and second film roll mounting and dispensing carriage assemblies can be achieved in accordance with automatic and semi-automatic modes of operation.
