    摘要： 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.

    摘要翻译： 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。

    摘要： The present invention provides a method and apparatus for dispensing a predetermined substantially constant length of pre-stretched packaging material based upon load girth. Based upon the girth of the load to be wrapped, an amount of pre-stretched packaging material to be dispensed for each revolution of relative rotation between a packaging material dispenser and the load is determined. A rotational drive system used to provide the relative rotation is linked to a pre-stretch assembly portion of the packaging material dispenser. The linkage may be mechanical or electrical. The linkage controls a ratio of the rotational speed to the pre-stretch assembly dispensing speed, such that the predetermined substantially constant length of pre-stretched packaging material is dispensed for each revolution of the packaging material dispenser relative to the load regardless of the speed of the rotational drive. In the case of a mechanical linkage, the linkage also connects the rotational drive to the pre-stretch assembly portion such that the rotational drive also drives the pre-stretch assembly portion.

    摘要： A film dispenser for a stretch wrapping apparatus is provided. The film dispenser includes a pre-stretch assembly having a top portion mounted to and extending downwardly from a drive plate of a roll carriage frame. The pre-stretch assembly includes two pre-stretch rollers having first ends connected to the roll carriage frame and second ends connected to one another. The pre-stretch rollers may be coated. The pre-stretch assembly further includes a cantilevered idle roller mounted to the drive plate and positioned between the pre-stretch rollers. A film path is defined by the space between the pre-stretch rollers and the idle roller. The film path is easily accessible via the bottom end of the pre-stretch assembly.
