Abstract: A device for rotatably supporting a roll of sheet material includes a frame rotatably supporting the roll. Arms on the frame support a cutter bar parallel to the axis of the roll and movable to bear resiliently against and follow the periphery of the roll. Spacing means having a convexly rounded head is fixed on the cutter bar spaced from its cutting edge, such that the cutter bar engages the roll only by said spacing member and adjacent said cutting edge.

Abstract: A tape dispenser which includes a portable frame having a single upright sidewall and an upwardly projecting front wall provided with a cutting blade adjacent the upper edge thereof. A pair of horizontally cantilevered spindle assemblies are rotatably supported on the sidewall in parallel but horizontally spaced relationship. One of the spindle assemblies, as positioned more closely adjacent the cutting blade, has a rotatable support roller on which a tape spool is removably positioned. This support roller also has a large diameter annular hub disposed in engagement with an endless drive belt. The other spindle assembly includes a rotatable takeup roller which is of a diameter similar to that of the support roller. This takeup roller, which is adapted to have the tape backing strip wound thereon, has a small diameter hub disposed in engagement with the drive belt.
