摘要： Precut and prescored tray blanks are stacked in a magazine, and pivoted vacuum cup means is adapted to withdraw the lowermost blank from the stack by moving the blank downwardly to a delivery position. Control means is provided for operation of the vacuum cup to move it from and to its pick-up position in engagement with the lowermost blank in the stack, the vacuum cup being vented to atmosphere when it reaches the delivery position. A continuously driven roller is adapted to receive the leading edge of the blank in this delivery position and a back-up roller swings on the axis of the driven roller so as to pinch the blank therebetween and to feed it downstream against a stop. Side guides loosely receive the edges of the blank as it moves against the stop, and inturned end portions of these side guides actually deform the side edges of the blank to hold it into position against the stop where it is engaged by mechanism associated with the tray forming apparatus.

摘要： An automatic machine is disclosed for packaging an array, or slug, of articles, such as cans, in a paperboard carton, wherein the carton is first provided in a flat blank form, is then preliminarily formed into a U-shaped configuration, and then final wrapped around the array of articles, to be subsequently glued up and sealed so as to form a very compact paperboard carton for the articles. The machine includes a frame having a vertically movable elevator structure which is equipped with laterally opposed plows for engaging side panels of the paperboard blank, and for folding the side panels upwardly into a U-shaped configuration around the funnel portion of a packer in which the articles are held prior to being dropped onto the bottom panel of the blank. After the articles are positioned thereon, the elevator structure lowers the U-shaped blank, together with the articles, onto a pocket chain conveyor where the carton is fed laterally off the elevator to fold the top panel, and to fold the end panels associated with the side panels, as well as those associated with the top and bottom panels, into place. A conventional vertical compression unit is also used, and the manufacturer''s tab or flap is glued and folded in this portion of the machine.

摘要： A film wrapping machine is disclosed for enveloping articles in a transparent, shrinkable film. The articles are translated serially onto a conveyor while a first film is fed between the articles and the conveyor and a second film is laid over the articles. A flight bar carrier folds or tucks the second film between the articles and presses the second film into contact with the first film. Heat is applied to the areas of contact between the two films so that the films become welded together in one or more seams as the articles and films are transported along the conveyor. A cutting mechanism severs the films between articles along or adjacent the welded seams. The separated articles enveloped by the films are then accelerated to a shrink tunnel which heats the films and causes them to shrink tightly against the article.

摘要翻译： 公开了一种薄膜包装机，用于将物品包封在透明的可收缩薄膜中。 将物品顺序地翻转到输送机上，同时在物品和输送机之间输送第一膜，并将第二膜放置在物品上。 飞行杆承载件在物品之间折叠或折叠第二膜并将第二膜压在第一膜上。 热量被施加到两个膜之间的接触区域，使得当制品和膜沿输送机输送时，膜在一个或多个接缝中被焊接在一起。 切割机构沿着或邻近焊接接缝处切割制品之间的膜。 被膜包围的分离的物品然后被加速到收缩隧道，加热膜并使它们紧紧地收缩在物品上。
