Abstract
An apparatus for the opening of paper bobbins and other rolls of material is provided. A flat blade is advanced from the side of a wound roll of material such that it intersects the roll over substantially its entire width. A cutting blade or other cutting mechanism then severs the layers of the roll which are outside the flat blade, and the flat blade protects the inside layers from being damaged. In preferred embodiments, a jet of air or other gas may be used to ease the insertion of the flat blade, or a gripping device which pinches the surface of the roll between opposed friction pads creates an arch in the surface of the roll through which the blade is inserted. The device is particularly suitable for use in cigarette making machines which require undamaged paper feeds.
