    • Method and device for moving a lifting slider of a lifting device, e.g. a lifting slider of a wrapping and packing machine for stretch film wrapping of goods positioned on a loading pallet. The lifting device comprises a lifting slider (6) driven by a hydraulic cylinder (14) through a wire (19), which doubles the movement of the hydraulic cylinder with. The hydraulic cylinder is powered by a hydraulic pump (21) which in turn is powered by the wheels (22) of the lifting device through a link means (25, 26). The hydraulic pump comprises two parallel cylinders (23, 24), which are driven so that always one of the cylinders performs a power stroke. The movements of the lifting slider are controlled by valves for performing a movement upwards, which is proportional to the speed of the lifting device, a blocked position and a lowering with constant speed.
    • 用于移动提升装置的提升滑块的方法和装置,例如, 用于包装和包装机的提升滑块,用于位于装载托盘上的货物的拉伸膜包装。 提升装置包括通过导线(19)由液压缸(14)驱动的升降滑块(6),其使液压缸的运动加倍。 液压缸由液压泵(21)供电,液压泵通过连杆装置(25,26)由提升装置的轮子(22)提供动力。 液压泵包括两个平行的气缸(23,24),其被驱动,使得气缸中总是执行动力冲程。 提升滑块的运动由用于执行向上移动的阀控制,其与提升装置的速度,阻挡位置和以恒定速度的下降成比例。

    • A self-propelled wrapping machine is movable around a product for wrapping the product with a film of plastics and comprises a self-propelled carriage (2) provided with directional wheels (9) and with a steering (11) for manoeuvring the directional wheels (9). The wrapping machine further comprises a spring (17) acting on the steering (11) such as to exert a torque on the steering (11) and induce the steering (11) to orient the directional wheels (9) according to a set work direction. The wrapping machine is further provided with a device (19) that is drivable by the steering (11) to exert a further torque, opposite the aforesaid torque, on the steering (11), such as to lighten the latter and thus facilitate an orienting manoeuvre of the directional wheels (9) according to a further direction. A further self-propelled wrapping machine is movable around a product for wrapping the product with a film of plastics and comprises directional wheels (9), steering around a rotation axis (R) to enable the machine to follow a desired movement path, a steering (11), for manoeuvring the directional wheels (9) along the movement path, and a spring (17), for exerting, along an application direction (d1), a force generating a torque on the steering (11) that is such as to induce the steering (11) to rotate the directional wheels (9) around the rotation axis (R) according to a set direction (D). The machine is further provided with a device (21, 23) that is controllable by the steering (11) and acting on the spring (17) for reducing the aforesaid torque such as to lighten the steering (11) and facilitate an orienting manoeuvre of the directional wheels (9) according to a further direction.

    • A method for wrapping a roll of steel (10) or other coiled material which includes the selection of a tear-resistant sheet (12) of proportions to accommodate a steel roll (10). The sheet is folded along lines parallel to its width, and holes are punched through the folded sheet at the upper and lower ends of the sheet, forming a plurality of upper holes and a plurality of lower holes. The sheet is unfolded and ropes or strings (18, 20) are threaded through each set of holes. A roll of steel (10) is placed on the sheet (12) and the sheet (12) is wrapped circumferentially around the roll (10) and secured with adhesive tape. The strings (18, 20) are then drawn tightly, pulling the sheet (12) radially over the roll of steel (10) such that the sheet (12) overlaps the aperture of the core of the roll (10).
    • 一种卷绕钢卷(10)或其他卷材的方法,该方法包括选择比例适合钢卷(10)的抗撕裂片(12)。 沿平行于其宽度的线折叠片材,并且在片材的上端和下端穿过折叠片材冲孔,从而形成多个上孔和多个下孔。 片材展开并且绳索或绳索(18,20)穿过每组孔。 将一卷钢(10)放置在所述片材(12)上,并将所述片材(12)周向缠绕在所述卷(10)上并用胶带固定。 然后将绳(18,20)紧紧地拉紧,将薄片(12)径向拉过钢卷(10),以使薄片(12)与卷(10)的芯的孔重叠。
