When a number of products of the same type are processed in exactly the same way, it is useful to have a conveyor belt which can intermittently feed the belt forward at certain lengths at a time. The invention concerns an arrangement for ensuring the movement of exact portions of the belt, and this is produced with the help of two cog wheels (3 and 4) which engage each other and with a two-way movement unit (2), which in one movement of direction engages one of the cog wheels (3), and in the opposite movement of direction engages the other cog wheel (4).<IMAGE> |
