The invention relates to a mechanism for advancing flat-laid package blanks (10) disposed in a magazine (14). A shaft (1) extending through the mechanism at right angles to the magazine (14) is journalled by means of a free-wheel hub (5) so that it may rotate in only one direction. The shaft (1) is urged against at least one endless elastic belt (9) which interconnects two or more wheels (11). In its turn, the belt (9) presses against the flat-laid package, blanks (10). The free-wheel hub (5) is surrounded by a lever (6), reciprocally pivotal and connected to a drive unit (8). When the lever (6) is pivoted in the one direction, the movement is transferred via the shaft (1) to the belt (9) and the package blanks (10) are fed forwardly in the magazine (14). When the lever (6) is pivoted in the other direction, the free-wheel hub (5) locks and no movement is transmitted to the belt (9) which might counteract the forward advancement of the package blanks (10) in the magazine (14). <IMAGE> |
