Abstract:
The invention concerns a process for the production of hollow bodies of thermoplastic material, in particular a process for the production of fuel tanks of plastic material. In the process according to the invention preforms in web or band form of plasticised plastic material are shaped in a multi-part tool forming a mould cavity by expansion of the preforms and causing them to bear against the internal contour of the mould cavity. The process firstly includes the production of two mutually complementary intermediate products in the form of shell portions. Then respective built-in fitment components are secured to the respective insides of the shell portions, which face towards each other in the installation position, wherein at least some built-in fitment components of mutually complementary shell portions are respectively of mutually complementary configuration, in the sense that they can be joined to provide an assembled component or to provide a functional unit. The shell portions are assembled in such a way that the mutually complementary built-in fitment components engage into each other and/or come into operative connecting relationship with each other.
Abstract:
An energy efficient method and apparatus for manufacturing a biodegradable, compostable, liquid-impermeable lined paper bag for containing wet (i.e. food) wastes by which all adhesives used in the process are cold glues applied without using heat and are applied through an extrusion and/or metering application means. Cellulose film is advantageously used for the paper liner and a dot matrix configuration of adhesive is applied between the cellulose and paper layers to laminate them together. The matrix-defined size of spacings between the points of application of adhesive on the cellulose film is such that both loss of the permeability of the cellulose film to water vapour and oxygen and creation of stress points on the cellulose film are minimized. A second cold glue is applied to the bag bottom section by a matrix of extrusion adhesive guns and programmable controller for activating the guns whereby the guns are activated according to a program of the controller for applying the second adhesive to pre-determined, programmable areas of the bag bottom section.
Abstract:
A method for jacketing a product having a generally cylindrical outer surface locates a sheet of jacketing material on first and second belts for conforming the sheet of jacketing material to and pressing the sheet of jacketing material against the outer surface of the product and locates the product on the sheet of jacketing material. Preferably, the belts are mounted on frames that are pivoted from a first position where the sheet of jacketing material can be placed on the belts and the product can be placed on the sheet of jacketing material to a second position where the belts are each wrapped part of the way around the outer surface of the product while the product remains stationary to conform the sheet of jacketing material to and press the sheet of jacketing material against the outer surface of the product so that the sheet of jacketing material may be bonded to the outer surface of the product. When the frames are pivoted from the first position to the second position, the frames draw the belts over the sheet jacket with a force less than that required to crush the product and greater than that required to overcome friction between the belts and the sheet of jacketing material.
Abstract:
A method provides instructions for the butt seam application of a surface covering laminate material. A quantity of a surface covering laminate is provided. A portion of the quantity comprises a web material having a first side and a second side. The first side comprises an adhesive. The second side is releasably joined to a release liner material. The first side of a first portion of the surface covering laminate is disposed in contact with a target surface. The first side of a second portion is disposed in contact with the target surface. At least a part of the second portion overlaps a part of the release liner of the first portion. The release liner is removed from the second portion. The release liner is removed from the first portion of the surface covering laminate together with that part of the second portion which overlaps the first portion.
Abstract:
A method for manufacturing a bag for use in vacuum packaging comprises forming a first panel including a tray for retaining contents within the bag and a second panel. Optionally, the tray can include a plurality of ridges or protuberances for suspending contents such that liquid can collect in the tray. Each panel comprises a gas-impermeable base layer and a heat-sealable inner layer molded from melt-extruded resin. The first panel is overlapped with the second panel, and three of four edges of the panels are heated such that the inner layers bond at the heated edges. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
Abstract:
The disclosure is directed to a method of manufacturing a booklet from a rectangular sheet of paper having information regarding a drug product printed thereon. The method comprises applying a first portion of glue to a first face of the sheet of paper along a single linear path, applying a second portion of glue to a second face of the sheet of paper along a single linear path, making a plurality of parallel folds in the sheet of paper in a direction transverse to the single linear paths along which the glue was applied to produce an intermediate item, and trimming the intermediate item in a direction parallel to the plurality of parallel folds to cause the first and second of the plurality of parallel folds to be removed from the intermediate item.
Abstract:
A method for manufacturing a bag for use in vacuum packaging comprises forming a first panel having a plurality of baffles for evacuating air and/or other gases from inside the bag using a suction source, while preventing liquids from being drawn into the suction source, and a second panel. Each panel comprises a gas-impermeable base layer and a heat-sealable inner layer molded from melt-extruded resin. The first panel is overlapped with the second panel, and three of four edges of the panels are heated such that the inner layers bond at the heated edges. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
Abstract:
This invention concerns a method for fabricating a curved beam from fiber composite material. A flat fiber composite laminate (2) comprising a plurality of layers and at least two different fiber directions is formed. The fiber composite laminate (2) is disposed in contact with a male tool (1) comprised of a first flange (1a), a second flange (1c) and an intermediate web (1b), which male tool (1) is curved in its longitudinal direction with a radius of curvature R in such a way that the first flange (1a) has a shorter longitudinal extent than the second flange (1c). The fiber composite laminate (2) is brought into contact with and secured to the first flange (1a) of the male tool (1). The male tool (1) and the fiber composite laminate (2) are then rotated relative to one another so that the fiber composite laminate (2) is brought into contact with the intermediate web (1b) of the male tool (1) in a first rotational movement, and brought into contact with the second flange (1c) of the male tool (1) in a second rotational movement. The fiber composite laminate (2) hardens on the male tool (1), and the finished beam is separated from the tool (1). The invention also relates to a beam of fiber composite material fabricated according to the method.

The present invention also relates to a machine that carries out said process, as well as the semimanufactured products obtained with said process or machine.
Abstract:
A method of making a pant having a front-to-back crotch seam includes providing a flat web. The flat web can be cut into separate pieces or cut to provide interconnected pieces and the center portion of each separate piece is removed. Slits are cut in each separate piece or each interconnected piece and the remaining attached segments are drawn away from each other in opposite directions to bring first and second seam edges together for the purpose of forming a garment shell with a crotch seam. The method may be applied to a single piece of material representing a single garment or to an interconnected web of garments. After forming the crotch seam, the garment shell can be folded and side seams formed. The pant may include an absorbent structure.
