ROLLED WEB DISPENSER AND CUTTING APPARATUS

摘要

A rolled paper towel dispenser having a spring (178) loaded cutting blade geared to rotate in conjunction with a slotted drive drum (54). The blade is shielded by a fixed cowl (34). Guide rollers (68, 70) and the drive drum include threading clips. A brake mechanism ensures that the rolled towel cannot be free spooled. Supports (25, 26, 86) are provided for both a primary roll and a stub roll. Geared sensor arms sense the diameter of the stub roll and when the diameter decreases to a point near the end of the roll, the tail from the primary roll is automatically delivered to the surface of the drive drum and automatically threaded therethrough. To dispense a towel from the dispenser, the user grasps the tail of the towel extending from the dispenser and pulls downward. This drives the drive drum which in turn rotates the cutting blade into position severing the sheet at the proper location.
