Abstract

A device for the reciprocating linear drive of a part, especially of a scraper at a calender cylinder, comprises a driver connected to the scraper and having two mutually parallel oppositely disposed abutments and an eccentric disposed between the abutments. The eccentric has an outside diameter which is smaller than the distance between the abutments. The eccentric is designed as a double eccentric with a driven inner eccentric fixed to a rotary drive shaft and with a freely movable outer eccentric floatingly mounted to the inner eccentric via an antifriction bearing.
