Abstract
Abstract A device for the simultaneous dispensing and cutting of wound materials comprising a rotatable drum mounted beneath mounted an articulated rolled carrier adapted for carrying a roll of material whose free end extends between the drum and roll carrier and projects from the device. By pulling the material from the device, the drum is caused to rotate and the material is unwound from the roll. A cutting device serves for severing the material at the end of a pulling action and this comprises a fixed blade member adjustable in position and a movable blade member which is driven with the drum and progressively severs the material over its entire width. A stop is positioned to engage the movable blade and hold the same in an inoperative position. An energy storage arrangement is coupled to the drum to resist its rotation in the direction of unwinding when the free end of the material is being pulled and withdrawn from the device until the blades cut the material, whereafter the drum is continued to be rotated by the energy storage arrangement in the direction of unwinding, until the movable blade again contacts the stop and a fresh length of material is fed from the device.
