| 摘要 |
The invention relates to a wrapping machine and/or top foil wrapping machine, comprising a machine frame (1) supported on a fixed base and comprising upright vertical columns (2); a lifting frame (3) arranged to be vertically movable upwards and downwards and guided by the vertical columns (2); a lifting motor (4) for moving the lifting frame, power transmission means for the transmission of power from the lifting motor to produce vertical motion of the lifting frame, said power transmission means comprising elongate flexible drive elements (5) and wheels for the transmission of the power of the lifting motor to the drive elements. The wrapping machine further comprises a foil dispenser (7), on which a foil web roll (8) can be rotatably supported. The top foil wrapping machine comprises a top foil depositor. The lifting motor (4) is secured to the lifting frame (3) so as to be movable with it. The wheels comprise a drive belt pulley (6) fitted for reeling a flat belt. The drive belt pulley (6) is rotatably mounted on bearings on the lifting frame (3) and rotated by the lifting motor (4). Each one of the elongate drive elements (5) consists of a drive belt whose first end (9) is secured to the upper end of the vertical columns while the second end (10) is secured to the drive belt pulley (6).
