<p>The paper-roll handler consists of two parts fitted telescopically. Each part has a tube (3, 4) which enters the central hole of the roll on either side. The two parts are formed of three parallel tubes (1, 2, 3), (7, 8, 4). The tubes are held rigidly by joinings (5, 6) (9, 10). The parallel tubes (1, 2) and joinings (5, 6) are integrally formed from one bent tube as are the tubes (7, 8) and joinings (9, 10). Two wheels (12) are fixed on one side and there are two telescopically mounted blades (13, 14) to cut the paper. The roll can be positioned vertically or horizontally.</p> |
