Abstract

Device for extemporaneously raising a transport roller in a feeder of a sheet processing machine, wherein the transport roller is swivelably arranged on a shaft supported crosswise in a frame of the machine above a feed table, so as to execute stroking movements in synchronism with the machine and be liftable from the feed table extemporaneously by a swiveling motion of the shaft, includes an entrainer disposed on the shaft, and an adjusting member formed with a coulisse, the entrainer engaging in the coulisse with a rotary angle clearance at least equivalent to the stroking movements in synchronism with the machine, the adjusting member being swivelable, out of a stop position and counter to a spring bias, about the shaft axis and through a rotary angle greater than the rotary angle clearance.
