Abstract: An improvement to prior art bag closure affixing devices of the type embodied in U.S. Pat. No. 3,163,967 to easily accommodate bags of various neck widths without the need for gear or sprocket changes. The improvement encompasses a modified clutch control for the bag closing head. The clutch is controlled by a clutch actuating arm which is mechanically connected to the clutch. When the actuating arm is depressed, the clutch disengages from a first stop surface and rotates only partially until engaging a second stop surface. The second stop surface remains in contact with the clutch, preventing completion of the closing cycle, until the bag neck completely passes over the actuating arm and the actuating arm is released. The second stop surface then disengages the clutch allowing the bag closing head to complete a closing cycle with bags of varying neck sizes without frictional damage to the bag or incomplete entry of the full bag neck.

Abstract: A method for producing bags (12) with carrying handles (48), for which the starting material for the carrying handles is supplied as endless material and at least two carrying handles are affixed to each finished or still unfinished bag, in which the starting material for the several carrying handles (48) belonging to one bag (12), to begin with, are supplied in the form of a single strip (20) of material, which then is divided up continuously into several parallel partial strips (38, 40) for the individual carrying handles.

Abstract: A novel food server and method of producing a food server is disclosed. The novel method includes moving a web of paper at a constant rate of speed, rotary perforating a plurality of lines on the moving web, using rotary timing belts to score at least two fold lines on the moving web, where the two fold lines define two glue flaps, rotary die-cutting the moving web to cut away portions of the paper adjacent the glue flaps, plow folding the moving web along the two fold lines defining the glue flaps, and applying glue to the moving web. After plow folding along the fold lines and applying the glue, the moving web is cross cut to form a blank having the glue flaps. Then, the blank is vacuum folded to cause portions of the blank to contact and adhere to the glue flaps, thereby forming the food server from the blank. The novel food server includes a first panel having two side flaps each defined by a score line, and a second panel having two side flaps each defined by a score line.

Abstract: An apparatus and method for making improved folded signature for subsequent use in gathering and combining or binding in bookbinding. Each folded signature includes uniquely positioned perforated folds, sequences of folding and adhered together perforated folded edges which reduce folding time, alter folded signature orientation during gathering, eliminate the need for having a conventional backbone, and provide a binding or pulling edge.

Abstract: An apparatus for making bags out of a thermoplastic web has a transport unit for feeding a leading end of the web in a transport direction to a cutting/welding station, tools at the station for transversely welding the web and cutting a bag from the leading end of the web, and a device downstream in the direction from the station for stacking and blocking bags cut from the web. A bag-pulling device between the station and the stacker/blocker has an endless drive strand having a pair of stretches extending vertically across a path of the bag between the station and the stacker/blocker and respective horizontally extending deflector rollers carried on the stretches, vertically displaceable therewith, each extending along a respective axis, and each having an outer surface engageable with the web and freely rotatable about the respective axis.

Abstract: An apparatus and method for making a beverage container which contains an instant beverage material individually sealed within the beverage container by a filter disk and an insert disk combination. The apparatus includes a mandrel having a flange and a forming die which is slideably mounted on the mandrel. The forming die has a chamfered outer surface which fits into a beverage container and an inner stepped portion which is configured to engage the flange of the mandrel and receive the filter disk and insert disk to be inserted into a beverage container. A funnel press is provided which has a funnel portion and a press portion. The press portion mates with the mandrel and forming die to draw a portion of the filter disk into the mandrel to simultaneously form a pocket in and crimp a filter disk which is subsequently loaded with an instant beverage material using the funnel portion.

Abstract: The present invention provides a method of producing a protective device that is adapted for use with a container in order to inhibit ingress of unwanted materials through a handhold opening in a wall of the container. The method includes a first step of advancing a first strip of material in a longitudinal direction from an upstream location to a downstream location. As this first strip of material is advanced, it is longitudinally scored after which a second strip of material is secured to the first strip of material such that the second strip is sealed around a discrete consecutive portion of the scoring. Thereafter, an adhesive material is applied to a side surface of the first strip opposite the second strip. The joined first and second strips are then cut into individual units with portions of the first and second strips in each unit being sealed completely around the periphery thereof.

Abstract: An opening part cuts a periphery of a package which contains a bundle of PS (photosensitive) plates. Then, a lifter separates a top piece of the package from the bundle of the PS plates, and a cartridge body, which has been transferred by the lifter, is put on the bundle of the PS plates from which the top piece of the package has been separated. An inverter inverts the top and bottom faces of the bundle of the PS plates covered with the cartridge body, and then, the lifter separates the bottom piece of the package from the bundle of the PS plates. A cartridge lid, which is transferred by the lifter, is put on the bundle of the PS plates from which the bottom piece of the package has been separated.
