VORRICHTUNG ZUM EINSPANNEN EINER MATERIALBAHNVORRATSROLLE, INSBESONDERE BEI EINER WELLPAPPENMASCHINE

摘要

A linerboard roll mounting device in a corrugator comprises a conveyor means (13) adapted to reciprocate between a stockyard and a mill roll stand (1), a litter (18) capable of ascending or descending below the rocking locus of the swing arms (3,4) of the mill roll stand, and a diameter detecting sensor (23) for detecting the roll diameter of the incoming linerboard roll. The linerboard roll is lifted up with a lifter (18) to the waiting position of the swing arms (3,4), when the value resulted from the above detection is determined to be insufficient for the center blocks to reach the paper tube of the linerboard roll if the swing arm of the mill roll stand is moved to its lowest rocking position, so that alignment of the center block and paper tube of the linerboard roll is adapted to achieve automatic chucking thereof. <IMAGE>
