Abstract: Several small diameter short width rolls (124) of plastic film (108) are wound from a larger width and length of plastic web in a continuous manner. The disclosed apparatus slits the larger width plastic web into several narrower width plastic webs, positions the slit webs on a single large diameter winding drum (110) and then winds each narrower width web at a separate winding turret (112, 114). At each turret, the plastic web is rolled around a first mandrel until the roll achieves the desired size. Then, a second mandrel contacts, the plastic web and the plastic web is severed between the first mandrel and second mandrel and attached to a second mandrel to be rolled into a roll of desired length. The process is repeated at each turret such that the several plastic webs are simultaneously wound in a continuous fashion.

Abstract: In a tandem media supply, two vertical stacks of media sheets are stored. The first stack is positioned on a lift plate that rises as top sheets are removed from the stack of media. When the first stack is exhausted, the second stack is moved by an actuator towards a position where the lift plate was loaded with the first stack of media sheets. Movement of the second stack displaces a biased gate to decouple the lift plate from a drive member that elevated the lift plate. The lift plate drops under the effect of gravity to a position where the second stack of media sheets moves onto the lift plate. Once the second stack is on the lift plate, a biasing force returns the biased gate to a position that enables the drive member to elevate the lift plate.
