Abstract
Apparatus for automatically deheading wrapped newsprint rolls consists of a framework positioned above a pair of rotatable rollers adapted to support and rotate the newsprint roll. Two carriages are slidably supported on the framework above the newsprint roll. Each carriage is independently movable axially relative to one of the opposite end faces of the roll, is provided with an annular locating member engageable with that end face, and has a radially movable cutter adapted to sever the head wrapping covering that end face as the newsprint roll is rotated by the supporting rollers. The annular locating member is mounted obliquely relative to the newsprint roll axis to compensate for deformation of the newsprint roll end face.
