ABSTRACT:
A circular cover of corrugated cardboard for application to one end face of a roll of convoluted sheet material has two mirror symmetrical tongues which can be pivoted along parallel bending scores out of the plane of the cover for introduction into one end portion of a tubular core within a roll by an apparatus having a depository for covers and a device which transfers covers from the depository to the end faces of rolls. The depository centers and turns the covers so that each cover is properly oriented relative to the transporting device. The latter has two pivotable pushers which can pivot the tongues of a properly centered and oriented cover and thereupon insert the pivoted tongues into one end portion of a core.
