Abstract: A method for packaging products, wherein packaging material web is transported in direction of an upwardly open pair of folding claws, is cut to length while forming a planar blank of the wrapper, and the blank is positioned above the folding claws, wherein the product is metered, the product portion is pre-shaped, and the blank by placing thereon the pre-shaped product portion is folded into the claws while forming the upwardly open wrapper. Thereafter, the upward-projecting lateral longitudinal peripheries of the wrapper are folded inward onto the product portion, whereupon the transverse peripheries of the wrapper which extend perpendicular thereto are folded inward onto the product portion. The lateral longitudinal peripheries and transverse peripheries of the wrapper are folded inward onto the product portion and are simultaneously connected to one another, while the wrapper provided with the product portion is still situated in the pair of folding claws.

Abstract: The invention relates to a device for forming sleeve-like foil envelopes from a continuous flat strip of a sleeve-like foil material, comprising supply means (12) for supplying the continuous flat strip of sleeve-like foil material (1), cutting means for making a cut in this strip of sleeve-like foil material over the full width thereof so as to obtain the individual sleeve-like foil envelopes, as well as discharge means (20a-20b) for discharging the individual sleeve-like foil envelopes from the device. The device of the invention is characterized in that the device comprises rotational element means (20?) arranged for imparting a rotary motion during operation to the sleeve-like envelope to be discharged from the device. By imparting a rotary motion to an individually formed sleeve-like foil envelope while it is being discharged from the device it is achieved that the foil envelope will remain open, making it possible to place the envelope round a container in a simple and effective manner.

Abstract: This invention concerns a method and a device for stacking and packing groups of infusion bags, especially for making tea, whereby in continuous production infusion bags arranged one after another in a series in a strand are separated, their speed of movement is reduced and they are put in a position suitable for making a stack, whereby the infusion bags are arranged one after another in such a way that they at least partly overlap in their subsequent direction of movement.

Abstract: The present invention relates to a process for converting a continuous structure into discrete, spaced apart elements by means of an expandable support web. First, the continuous structure is combined with a support web comprising longitudinal expansion means. Then, after separation of the continuous structure into discrete elements, the discrete elements are spaced apart by expanding the support web. The process of the present invention is particularly well suited for the industrial manufacture of articles comprising fragile discrete elements supplied to the production process in continuous form.

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 for the dimensionally accurate cutting of a product carrier (1) which is in the form of a strip, is transported further in a cyclic or continuous manner in the longitudinal direction and has cells which are arranged one behind the other and are sealed in an airtight manner comprises a rotating cutter roller (15), which severs the product carrier (1) in each case in the region of a sealing web (4) which is situated between two cells (2), is arranged transversely with respect to the longitudinal direction and is provided with a lattice-like embossing (19). In order to identify and localise the sealing web (4), an optical reflection sensor (6) is arranged above and/or below the product carrier (1) and generates an AC voltage signal which corresponds to the lattice structure when the sealing web (4) is located in the region of the reflection sensor (6), the number of periods being a measure of the width b of the sealing web (4).

Abstract: A system for receiving tubular formed film comprising two facing walls and forming plastic bags having headers, open mouths and sealed bottoms into a block or stack of bags. The system includes an opener means for severing a spaced perforation on only one wall of the film to make a bag with an open mouth.

Abstract: A method of manufacturing folding paper sacks, especially gusseted sacks, wherein each sack is shaped out of a tubular section separated from a single- or multiple-layer tubular web and closed at both ends with folded bottoms is characterized in that each tubular section continues to be conveyed uninterruptedly parallel to the direction of travel of the tubular web once it has been separated from the tubular web and the forward and/or rear ends of the tubular sections are shaped during the continuous pass by prefolding and crimping over and by the application of adhesive to the folded bottom, transversely to the direction C of travel, and accordingly sealed.

Abstract: Apparatus for making bags from a folded web of thermoplastic material includes a rotating drum to which the web is continuously applied. As the drum rotates through a given arc length, the web is tucked outwardly from the periphery of the drum in progressively deeper folds wherein the depth of tuck determines the width of the bag. A cam, controlling the depth of tuck is movable in a rectilinear radial direction for adjusting the depth of tuck, thereby controlling the bag width.

Abstract: An envelope forming machine includes frame means supporting envelope blank feed means for feeding envelope blanks from an upstream end serially past aligner means, a printer transfer roller positioned adjacently above selectively operable printer means, scoring means and folding means to an envelope delivery station, with a release paper patch applying means being positioned above the transfer roller to apply a patch of release paper to adhesive on a flap of each envelope as each envelope flap passes over the printer transfer roller which serves as a backup roller against the flap during the application of the patch of release paper to the envelope flap.
