Abstract: Method and apparatus by which bread loaves or the like are split in half, and thereafter turned mechanically through 180.degree. with respect to one another so that the heel and cut ends of both of the two half loaves are oriented in the same way. The half loaves are thereafter sliced and then packaged in separate packages but in the same orientation with respect to each package.
Abstract: In a packaging machine, a folder assembly for folding the tops of bags as part of a ceiling operation wherein the folder assembly can accommodate irregularities in the bags without jamming. A first folding station includes a stationary support member to which is hingedly affixed a first and a second folder plate, each having predetermined profiles formed along a working edge thereof. These folder plates are resiliently biased by springs toward their associated support member such that limited freedom to yield in a vertical plane is achieved. Associated with the working edge and spaced slightly therefrom is a front fold blade which, too, is spring mounted to allow a limited yield in a horizontal plane. In the event a jam should occur, the assembly may be readily opened to facilitate the clearing of that jam.
Abstract: A method and apparatus for volume filling of storage boxes with discrete articles such as lemons in which a transitory fill box is provided with three sides, an open side to receive articles into the box at a level approximately that of the bottom wall of the fill box, the bottom wall being openable to deposit articles in a storage box in a gentle manner. Presence of articles sensed at approximately the bottom of the open side of the fill box cause the fill box to be incrementably lowered into the storage box so that articles entering the fill box enter at a level with minimum fall to the bottom wall of the fill box or to a previously deposited layer of articles. As the fill box is lowered a curtain wall closes the open side below the point of entry of the articles.
Abstract: This relates to starting up of a machine wherein a thermoformable web forms bottom of a sterile chamber in the machine and wherein it is necessary to sterilize all of the interior of the machine including forming and filling equipment as well as heating equipment. It has been deemed advisable to use as a sterilizing agent super-heated air. However, the temperature of the sterilizing air is above the melt temperature of the thermoformable web which normally forms the bottom closure for the sterile chamber.

Abstract: A corrugated box forming, loading and sealing machine, including a first or magazine and infeed section, a second or forming and loading section, and a third or closing and discharge section. In the first section there is stored and fed one-at-a-time flat corrugated blanks consisting of bottom, front, back and two top-half panels, all with extended edge panels, while glue is applied to the bottom, front and back edge panels. In the second section a product, such as cartons or plastic bottles, and two side panels, are loaded from opposite sides onto the bottom panel. When full, the loaded bottom panel is lowered through an opening whose four edge portions cause the front and back panels, and their respective edge panels to wrap around the product.
Abstract: In order to envelop the necks of a series of continuously moving bottles with decorative or informative tubular attachments, an elongate tube of heat-shrinkable plastic material is flattened first in one longitudinal plane and then in another longitudinal plane, perpendicular to the former, to produce a sheath with two substantially flat sides bearing the traces of a first pair of creases while being bounded by a second pair of creases. The longitudinally advancing sheath is cut into clippings of predetermined length that are advanced codirectionally therewith but at higher speed along a sloping guidepath in which the existing creases are caused to converge while the original creases reappear as the two sides are progressively spread apart.
Abstract: Apparatus for securing plastic film about a product including a curved forming plate, sealer means cooperating with the plate to form spaced discrete heat seals in overlapping portions of plastic sheet disposed about the plate and product, and transport means for reciprocatably moving the sealer means so that it remains in engagement with overlapped sheet portions and follows the path of movement thereof for a predetermined period of time.
