Abstract: Formed film, apparatus and methods for manufacturing formed film, and articles of manufacture are disclosed. Methods include controlled introduction of melt foldovers through modifying the surface area of a polymer melt curtain. Apparatus for same is also shown as are articles of formed film with melt foldovers.

Abstract: Embodiments of a thin web comprising a plurality of channels extending through the film are disclosed. The channels are in a substantially closed position but are capable of being in an open position to allow flow from the female side through the film to the male side. In certain applications, a greater pressure on the female side than the male side is capable of opening the channels. Embodiments may also include a thin web comprising a plurality of three dimensional apertures extending through the plastic film. The apertures may form a substantially closed channel defined by a sidewall and the channels being disposed at an angle greater than 70° with respect to a female side of the film. The thin web may be a plastic film or a thermoplastic film comprising a polyolefin, for example, or any other suitable material. The polyolefin may comprise at least one of polyethylene, polypropylene, low density polyethylene, or high density polyethylene, for example.

Abstract: A webbed reinforcing strip for poured concrete structures includes a first elongated tension strand, a second elongated tension strand spaced apart from and substantially parallel to the first tension strand, and at least two pairs of strands interconnecting the first and second tension strands in an open weave pattern. The interconnecting strands cross each other between the tension strands to form a webbed central portion of the strip. The interconnecting strands bend to join the tension strands at nonperpendicular angles at a plurality of nodes. All strands are formed of glass fiber reinforced plastic material and are bonded together with a bonding resin. Thus, thermal transfer and the potential for damage due to corrosion are minimized.

Abstract: A structural tie shear connector utilized in a concrete and insulation sandwich wall panel having first and second wythes and an insulation layer interposed therebetween. The connector includes first and second horizontal strands of thermally non-conductive material which are adapted to be encased by the respective wythes. A transverse web of thermally non-conductive material interconnects the first and second strands through the insulation layer. The web includes strands formed into a lattice structure. At least one of the strands of the lattice extends at an angle with respect to one of the first and second strands so as to be in tension when a load is applied to the wall panel. The connector resembles a bow tie.

Abstract: The present invention provides an improved method for laminating a first three-dimensional apertured or non-apertured film material to a second flat or three-dimensional apertured or non-apertured film material utilizing the heat generated by the extrusion of the first and/or second materials and the films produced thereby.
