Abstract
In one embodiment, a roll spindle comprises two roll supports and a differential.
Claims14
Roll spindle, comprising
- an axis of rotation,
- two roll supports extending along the axis of rotation, and
- a differential arranged to distribute a torque to each of the supports, wherein an outer dimension of the differential is equal to or less than an outer dimension of the supports so that a roll can slide over the differential;
- and
- a blocking arrangement arranged to block the supports from rotating with respect to each other so that both have equal rotational speed when the spindle is rotated by an external drive.
2 more elements
A method of processing rolls, comprising
- in a first action, mounting multiple rolls onto a spindle having multiple supports, so that each roll is supported by a respective one of the supports,
- using a differential to simultaneously drive the supports so that each support has an equal torque;
- and
- in a second action, removing the multiple rolls and mounting a single roll, a portion of which is supported on each of the multiple supports, and blocking one of the supports from rotation with respect to the other support.

A method of processing rolls of a print medium in a printing system, comprising
- in a first action, mounting multiple rolls of print medium onto an elongated spindle, the spindle having multiple supports so that each roll of print medium is supported by a respective one of the supports,
- using a differential to simultaneously drive the supports so that each support has an equal torque;
- in a second action, removing the multiple rolls of print medium and mounting a single roll of print medium on the spindle, a portion of which is supported on each of the multiple supports;
- and
- blocking one of the supports from rotation with respect to an adjacent support of the multiple supports.
