<p>A sheet dispenser for dispensing thin film such as collagen film (18) for wrapping food. The dispenser consists of a cabinet (8) in which a row of collagen film (18) is supported on rollers (14, 16) and the film (18) is pulled off the roll (10) by driven rollers (20, 22). When a predetermined length has been pulled off the roll (10) it is severed by a hot wire system in which the hot wire (24) is located between rollers (30, 32) supported in a tension head (26) controlled by spring (28). A cutter bar (34) supported on pivoted arms (40, 42) moves across so as to press the film (18) against the hot wire (24) during the cutting action.</p> |
