    • A packaging machine comprising: a tube forming section; a grouping section; a separating section and a sealing section. In the tube forming section, a tube of packaging material, preferably a shrink film, is formed. The tube then moves downwardly through the remaining sections of the machine. Articles to be packaged within the tube of packaging material are fed to the top of said machine and are allowed to travel downwardly aided by the action of gravity into said tube. With the articles thus positioned within said tube, they are grouped into an arrangement suitable for packaging. The groups thus formed travel downwardly aided by the action of gravity into the separating section and are separated within the tube by a distance sufficient to afford adequate packaging material for tucking at each end of the respective groups. With said material thus tucked at each end, the packaging material is secured in place to thereby form a package. In a preferred embodiment, the material is secured in place by the shrinking thereof.
    • 一种包装机,包括:管形成部分; 分组部分 分离部分和密封部分。 在管形成部分中,形成包装材料管,优选收缩膜。 然后,管子向下移动通过机器的其余部分。 要包装在包装材料管内的物品被供给到所述机器的顶部,并允许其通过重力作用向下运动到所述管中。 由于这些物品如此定位在所述管内,因此它们被分组成适合于包装的装置。 如此形成的组织通过重力作用向下运动进入分离部分,并在管内分离足够的距离,以足以提供用于在各组的每个端部折叠的足够的包装材料。 由于所述材料因此在每个端部被卷起,所以将包装材料固定就位从而形成包装。 在优选实施例中,通过其收缩将材料固定就位。
