    摘要: Improved apparatus for cutting an elongated paper tube or core mounted on a mandrel into a plurality of identical length core segments has a single control lever which when pivotally moved, actuates a cam and through a linkage system expands a portion of the mandrel against the core. A push button on the control lever electrically controls the rotation of the mandrel while continued pivotal movement of the lever moves a circular cutter into the tube to be cut. An adjustable stop member which is articulated to permit the loading of new cores pivots with the control lever to permit core segments to fall away from the mandrel as they are severed from the tube. A polyurethane ring on the mandrel provides a long lasting anvil surface for the cutter.
