Abstract
A sheet dispenser for dispensing thin film such as collagen film for wrapping food. The dispenser consists of a cabinet in which a row of collagen film is supported on rollers and the film is pulled off the roll by driven rollers. When a predetermined length has been pulled off the roll it is severed by a hot wire system in which the hot wire is located between rollers and supported in a tension head controlled by spring. A cutter bar supported on pivoted arms moves across so as to press the film against the hot wire during the cutting action.
