Paper dispensing apparatus comprises a web feed system in combination with a roll transfer system for dispensing paper from successive rolls thereof. The web feed system comprises, on respective shafts (16, 26), two pinch rollers (8, 10), in the nip of which is the paper sheet. Fast with roller (8) is a disc (32) on which is eccentrically disposed a button (34) attached to one end of a spring (50) anchored at its other end. The paper sheet is pulled manually, rotating roller (8) against the bias of spring (50) until a stop (36) engages a catch (39) on a sprung arm (38) having a push button (40). The length of paper is then torn off. Pushing button (40) releases the stop (36), so that a short length of paper is ejected for the above pulling. The roll transfer system comprises a spring roller contacting a first paper roll (4). Through a latch system, a transfer roller (76), holding the free end of a further paper roll, not shown, introduces the free end into the nip of rollers (8, 10) once the first roll (4) is substantially exhausted. <IMAGE> |
