Abstract
A variable acceleration TAR. The properties and dimensions of the sheets in a stack are entered by a user or determined automatically. Since it is known from either customer provided input or automatic sensing what sheet length and resulting pitch size are feeding from any tray, the acceleration profile for the TAR is customized according to how much time is available to bring the sheet to transport speed in a given pitch zone. For longer sheet length with higher mass, there is also more acceleration time available and can reduce the required acceleration to a value that the motor and drive nip friction can handle thereby keeping motor size down and making more efficient use of the available torque of the motor with no added cost.
