    Abstract: An apparatus for making a film bag with reinforced bag seams includes a film extruder that produces a continuous tube of film. A flattener produces a continuous web of flattened film which has an upper surface and a lower surface. A fold maker has a receiving portion positioned above the web and a displacing portion is positioned below the web that moves cyclically upward to a first position to locate a portion of the web into the receiving portion, thereby forming a fold. A fold retention device prevents the fold from opening. A presser flattens the fold against the web. A sealer seals through the fold, forming a reinforced bag seam. A cutter severs a sealed portion from an unsealed portion of the web. A transport mechanism moves the film from the extruder, through the flattener, into the fold maker, beneath the presser, into the sealer and to the cutter.

    Abstract: A fiber reinforced core panel is formed from strips of plastics foam helically wound with layers of rovings to form webs which may extend in a wave pattern or may intersect transverse webs. Hollow tubes may replace foam strips. Axial rovings cooperate with overlying helically wound rovings to form a beam or a column. Wound roving patterns may vary along strips for structural efficiency. Wound strips may alternate with spaced strips, and spacers between the strips enhance web buckling strength. Continuously wound rovings between spaced strips permit folding to form panels with reinforced edges. Continuously wound strips are helically wrapped to form annular structures, and composite panels may combine both thermoset and thermoplastic resins. Continuously wound strips or strip sections may be continuously fed either longitudinally or laterally into molding apparatus which may receive skin materials to form reinforced composite panels.

    Abstract: Process for manufacturing a plastic hollow body, the process comprising the following steps: a) a tubular stream of molten plastic is extruded; b) this stream is taken up by means of a tensioning device; c) a transverse cut is made in this stream so as to create a parison having one free edge that is not taken up by the tensioning device; d) the parison is moved relative to the tensioning device so that the free edge of the parison is also taken up by the tensioning device; and e) at least one longitudinal cut is made in the parison over its entire length. Equipment suitable for implementing this process.

  • Patent number: 7972546
    Abstract: Useful composites and methods of using such composites are provided. The composites include an outer layer containing a first polymeric material, an intermediate layer circumscribed by the outer layer and containing a second polymeric material, and an inner layer circumscribed by the intermediate layer and containing a third polymeric material. The inner layer, in combination with the intermediate layer, is structured and effective to reinforce the composite relative to a substantially identical composite without the inner layer. The present composites can be produced using co-extrusion processing.

  • Patent number: 7959851
    Abstract: Strips containers are formed using two continuous webs in thermoformable and heat-sealable material facing each other. The webs are indexed along a feed line through different operating stations that transform the webs into a continuous strip of containers, each one of which is provided with a mouth. The containers are arranged according to two parallel rows that are opposed to a longitudinal median zone. The mouths of the containers of the upper row are arranged on the upper longitudinal edge of the strip and face upwards, whilst the mouths of the containers of the lower row are arranged on the lower longitudinal edge and face downwards. The method enables productivity to be increased and waste to be reduced.

  • Patent number: 7879278
    Abstract: Methods for manufacturing panel units may include applying a cover tape to a surface of a panel in such a way as to substantially extend along a periphery of the panel. An extrusion molding die may be moved relative to the panel in such a way that the extrusion molding die moves along the periphery of the panel while at least partially contacting the cover tape applied to the panel. At the same time, a molten molding material may be extruded from the extrusion molding die, thereby integrally forming a molded article on the periphery of the panel. The cover tape may be then removed from the surface of the panel in order to produce a panel unit having the molded article disposed along the periphery of the panel.

  • Patent number: 7850888
    Abstract: Extruded, striped drinking straws are formed by coextruding at least two polymers of different color through a common extruder to form an elongated tube. An oscillator consisting of a pair of rolls supported for rotation about their central axes, extending normally to the extension of the tube, bear against opposed sides of the tube and are reciprocated in opposing directions so as to rotate the tube by a gear and spline mechanism. A straight puller draws the tube out of the extruder and through the twisting oscillator and a cutter forms the tube into straw lengths at the output of the puller.

  • Publication number: 20100298945
    Abstract: A radiation crosslinked (50 kGy), pressure-treated UHMWPE material has been developed by applying compressive force on a crosslinked polymer in a direction orthogonal to an axial direction. The deformed material is then cooled while held in a deformed state. The resulting material is anisotropic, with enhanced strength oriented along the axial direction. The directionally engineered material is oxidatively stable even after four weeks of accelerated aging in a pressure vessel containing five atmospheres of oxygen (ASTM F2003). Because of its oxidative stability, the deformation processed material is a suitable candidate for air-permeable packaging and gas sterilization, which has thus far been reserved for remelted highly crosslinked UHMWPEs.

  • Patent number: 7815830
    Abstract: The invention relates to a method for extruding curved extruded profiles. The extruded profile is formed in a matrix mounted upstream in a counter beam of an extruder system and is subsequently curved or bent due to the effect of external forces and separated, supported and arranged into partial lengths in the extrusion flow by means of a separating robot connected to a higher control mechanism and is discharged to a storage area with the aid of a handling robot. The handling robot is coupled to the separating robot by means of the control mechanism and, like the separating robot, is moved into a starting position in front of the extrusion press.
