    • The present invention provides a method and apparatus for dispensing a predetermined fixed amount of pre-stretched packaging material based upon load girth. A non-rotating ring carries a belt driven by a motor. A packaging material dispenser is mounted on a rotating ring, and the rotating ring may include a pulley that connects to the band, such that the rotating ring is driven by the drive belt. Based upon the girth of the load to be wrapped, an amount of pre-stretched packaging material to be dispensed for each revolution made by the rotating ring is determined. Good wrapping performance in terms of load containment (wrap force) and optimum packaging material use is obtained by dispensing a length of pre-stretched packaging material that is between approximately 90% and approximately 120% of load girth. Once the amount of packaging material to be dispensed per revolution is determined, a ratio of rotating ring drive to final pre-stretch surface speed (i.e., number of pre-stretch roller revolution/rotating ring rotation) can be set and mechanically controlled. Thus, for each revolution of the rotating ring and dispenser, a predetermined fixed amount of packaging material is dispensed and wrapped around the load. In an alternative embodiment, the ratio is electronically controlled.
    • 本发明提供一种用于基于载荷环分配预定固定量的预拉伸包装材料的方法和装置。 非旋转环带有由马达驱动的皮带。 包装材料分配器安装在旋转环上,并且旋转环可以包括连接到带的滑轮,使得旋转环由驱动带驱动。 根据要包裹的负载的周长,确定由旋转环制成的用于每次旋转的预分配的预拉伸包装材料的量。 通过分配一定长度的预拉伸包装材料,在负载围绕(包裹力)和最佳包装材料使用方面具有良好的包装性能。 一旦确定了每转需要分配的包装材料的数量,就可以设定并机械地控制旋转环驱动与最终预拉伸表面速度的比率(即,预拉伸辊旋转/旋转环旋转数)。 因此,对于旋转环和分配器的每次旋转,将预定的固定量的包装材料分配并缠绕在负载上。 在替代实施例中,该比率是电子控制的。

    • An apparatus for wrapping a load with packaging material may include a packaging material dispenser for dispensing packaging material. The apparatus may also include a relative rotation assembly for providing relative rotation between the load and the packaging material dispenser. The apparatus may further include a mechanical connection operatively coupling the packaging material dispenser to the relative rotation assembly. The relative rotation assembly may be configured to drive the packaging material dispenser through the mechanical connection. The apparatus may further include a force exerting mechanism operatively coupled to the mechanical connection. The apparatus may further include a sensing element configured sense a characteristic of dispensed packaging material. The sensing element may be operatively coupled to the mechanical connection. The force exerting mechanism and the sensing element may be configured to control the mechanical connection to maintain a selected ratio of packaging material dispensed to demand for packaging material at the load for at least a portion of a wrap cycle.
