摘要： An apparatus and method for wrapping a top and bottom of a load with packaging material is provided. The apparatus includes at least one non-driven packaging material guide is provided for use in combination with a powered conveying surface. The non-powered packaging material guide includes at least one row of non-driven wheels attached to a rail. The force applied by the packaging material as it is wrapped around the guide is supported by both the rail and the at least one row of non-driven wheels. The rail also serves to bridge any gaps between the non-driven wheels, thereby preventing capture of packaging material between the non-driven wheels. Preferably, the packaging material guide includes two rows of non-driven wheels, one on each side of the rail. Further, it is preferable that the rail connect the two rows of wheels such that the two rows of wheels form an angle of 60 degrees between them. The packaging material guide is preferably positioned above the load but may also be positioned either below the load or to the sides of the load.
摘要翻译：提供了用包装材料包装负载的顶部和底部的装置和方法。该装置包括至少一个非驱动包装材料导向器，用于与动力输送表面组合使用。非动力包装材料导向件包括连接到轨道的至少一排非从动轮。由包装材料围绕导向器缠绕的力施加的力由轨道和至少一排非从动轮支撑。轨道还用于桥接非从动轮之间的任何间隙，从而防止在非从动轮之间捕获包装材料。优选地，包装材料导向件包括两排非从动轮，一列在轨道的每一侧上。此外，优选的是，轨道连接两排轮，使得两排轮在它们之间形成60度的角度。包装材料导向件优选地定位在负载上方，但也可以位于负载的下方或负载的侧面。

摘要： A non-powered packaging material transporting surface for use in combination with a load support surface of a wrapping apparatus for wrapping a top and bottom of a load is provided. The non-powered packaging material transporting surface includes non-driven rollers aligned in an inline configuration, and a packaging material support guard adjacent to the non-driven rollers. The packaging material support guard bridges gaps between the inline rollers, thereby preventing capture of packaging material between the non-driven rollers. The non-driven rollers rotate as packaging material, wrapped around a load on a top surface of the load support surface and around the non-powered packaging material transporting surface on the underside surface of the load support surface, is moved along the transporting surface.
