Abstract: An improved film sealing and cutting apparatus (10) for use with a shrink-wrap machine that individually wraps articles (219) sequentially with shrink-wrap film material (200) of different possible thickness and composition, especially thick, tough film which would be difficult to seal. The apparatus (10) includes two pairs of selectively heated rollers (97, 98).

Abstract: A device for binding a stack of media sheets using imaging material as the binding agent. The binding device includes a tray for supporting the stack and a heated platen or some other type of imaging material activator near the tray. A press coupled to the activator is operative between a first position in which the activator is separated from the stack to a second position in which the activator contacts and compresses the stack at the binding region. A spring or other biasing mechanism operatively connected between the press and the activator biases the activator against the stack when the press is in the second position. The biasing mechanism allows pressure to be maintained on the stack to reactivate the imaging material without continuing to power the press down against the stack even as the stack shrinks under the reactivating pressure. Hence, power can be diverted if necessary or desirable from the press to activator to reduce the overall power consumption of the binding device.
