    • 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).
    • 本发明涉及一种用于推进布置在盒子(14)中的平板包装坯料(10)的机构。 延伸穿过机构的与轴颈(14)成直角的轴(1)通过一个轮毂(5)被轴颈支承,使其可以在一个方向上旋转。 轴(1)被推靠在与两个或更多个车轮(11)相互连接的至少一个环形弹性带(9)上。 反过来,带(9)压靠平整的包装坯料(10)。 自由轮毂(5)由杠杆(6)包围,该杆(6)可往复枢转地连接到驱动单元(8)。 当杠杆(6)沿一个方向转动时,该运动经由轴(1)传送到带(9),并且包装坯料(10)在料盒(14)中向前馈送。 当杠杆(6)沿另一个方向枢转时,轮毂(5)锁定,并且没有移动被传递到带(9),这可能抵消料仓(10)在料仓中的向前推进 14)。
