Method and apparatus for making gusseted packages having openable and reclosable interlocking seals, the seals having male and female portions, snap detents, and formed transversely to the direction of film flow. The packaging film is provided at package length intervals with thermoformable strips secured thereto transversely to the running length of the film, and is fed to a modified standard vertical form, fill and seal packaging machine with gussets forming tooling where the film is formed into a bag with the thermoformable strips inside at the upper end of the bag, product deposited into the bag, the bag sealed, the reclosable interlocking seal formed, and the bag severed from the next bag being formed. The reclosable seal provides auditory and tactile indications of seal closing. Some packages are formed with the thermoformable strips in the gusset, and some are formed with the gusset free of strip material.

Um die Enden von flachliegenden und mit Seitenfalten (2) versehenen Schlauchfolienbahnen (1,8) aus thermoplastischem Kunststoff in der Weise miteinander durch eine Querschweißnaht (10) zu verbinden, daß die Innenfalten von außen her auch im Verbindungsbereich durchgängig bleiben, wird ein Ende mit die Innenkanten der Seitenfalten auftrennenden Schnitten versehen. Das andere Ende wird in den aufgeschnittenen Bereich in der Weise eingeschoben oder eingelegt, daß die beiden Wände mit je einer Lage (4,6) jeder Seitenfalte des Endbereichs der einen Schlauchfolie (1) das andere Ende zwischen sich einfassen. In die Seitenfalten des eingefaßten anderen Endbereichs werden Trennschichten (9) eingeschoben oder eingelegt und die Enden werden sodann durch eine Querschweißnaht (10) miteinander verbunden.
摘要:
An improved reinforced laminate for use in sails or other flexible sheet or membrane applications utilizes a pull-truded thin lightweight reinforcing sheet of unidirectional extruded monofilaments in which the reinforcing sheet or sheets (32, 34, 36) form one or more uni-tapes laminated to a polymer film (40) such as Mylar R, or other extended sheet of material. The monofilaments (38) are uniformly embedded in the uni-tape via an elastomeric polymer matrix, with the reinforcing sheet, when incorporated into sails via lamination resulting in sails with reinforcing monofilaments having diameters 5 times less than conventional strands or threads. The use of small diameter monofilaments greatly increases the monofilament-over-monofilament crossover density, resulting in a dramatic increase in shear strength, and Young's Modulus, with an accompanying dramatic decrease in weight. In one embodiment the improvement in specific modulus over conventional sail laminates is about six-fold. For example, at only one-third the weight, stretch resistance is two times better. In a preferred embodiment, autoclaving is used in the lamination process to rid the laminate of voids which dramatically reduce shear strength by as much as 30 percent. Alternative void-free laminating processes include a silicone interliner/heated platen technique.

A tape applicator head (114) for applying two different types of fiber impregnated tape in two opposing directions onto a working surface. The head (114) includes a first dispensing apparatus (16) for one of the tapes, and a second dispensing apparatus (116) for the other of the tapes. The first dispensing apparatus (16) compacts the tape dispensed by the second dispensing apparatus (116), when the second dispensing apparatus (116) dispenses in one direction. When dispensing in the other direction, the second dispensing apparatus (116) compacts the tape which it dispenses. The first dispensing apparatus (16) compacts its tape in both directions.

Verpackung für Lebensmittel wie insbesondere halbfertige Backwaren mit einer beutelförmigen Innenverpakkung (10) zur Aufnahme des Lebensmittels und einer Faltschachtel, weiche die Innenverpackung umgibt. Die Innenverpackung (10) besteht aus Pergamentersatzpapier oder ähnlichem, ist an ihrer Aussenseite hitzebeständig beschichtet und besitzt eine Längsnaht (12), in der die Innenflächen der Ränder (13, 15) zusammengeklebt sind. Einer der beiden Randstreifen (13a) ist verlängert und umgefaltet, so dass er mit seiner Innenseite nach aussen neben der Längsnaht (12) liegt und mit der Innenseite einer inneren Verschlussklappe (7) der Faltschachtel abtrennbar verklebt ist. Zum Verschliessen der Faltschachtel werden zunächst Staubklappen (8) eingefaltet und hiebei wenigstens die Ränder der Innenverpackung (10) zusammengedrückt, danach die inneren Verschlussklappen (7) und die äusseren Verschlussklappen (6) eingefaltet.
摘要:
The invention concerns a container for food products or other sensitive products, said container being made of a material that intends to provide the container with gas-tight properties and that comprises a layer that exhibits no or only a low translucence to light. The invention is characterized in that at least one opening is provided in the layer with no or low light translucence such as to allow light for non-destructive detection of gas inside the container to enter and exit through said at least one opening. The invention also concerns a method for detecting gas inside a sealed container of the above type and a method for manufacturing of a container of the above type from blanks of a cardboard based material. The invention also concerns a production system comprising an apparatus for filling containers of the above type with a product and an apparatus for sealing the filled containers, wherein the system further comprises an apparatus for carrying out the method for detecting gas inside the sealed container.
摘要:
This invention relates to methods for processing floor coverings (100), such as carpet and/or carpet tile, having at least one layer containing a polyurethane (104), such that at least this polyurethane-containing layer (104) can be recycled and reused. The method involves contacting the floor covering (100) with an organic polyol (110) and heating (120) it, so that the polyurethane-containing layer (104) softens and/or partially liquefies, but can be resolidified by contact with additional polyisocyanate (140).
摘要:
A leakproof carton formed from a foldable carton blank (2) which has a first sheet of relatively flexible material (50) secured along its lower edge portion (56) to the top of the sidewall panel portions (14, 16, 18, 20) and the glue tab panel portion (22), a second sheet of relatively flexible material (60) secured along its upper edge portion (66) to the bottom of the sidewall panel portions (14, 16, 18, 20) and the glue tab panel portion (22). Either a continuous coating of a plastic material or a film of a relatively flexible plastic material may be secured to the inner surfaces of the first and second sheets and the portion of the sidewall panel and glue panel portions therebetween.
