    Abstract: The present invention relates to a reinforced thermoplastic film comprising a base film wherein the base film comprises a stretchable polyolefin material comprising one or more layers and a plurality of extruded reinforcing fibre elements. The extruded reinforcing fibre elements are located on at least one surface of the base film and form fibre protrusions relative to the surface plane of the base film. At the location where each reinforcing fibre element is provided on the base film, an interface is formed comprising direct interactions between a base film domain and a protrusion domain. The base film domain is a domain of pure base film material and the protrusion domain is a domain of pure reinforcing fibre element material. The interface between the base film domain and the protrusion domain is interrupted by one or more discrete intermixed domains, wherein the intermixed domains comprise a material mixture comprising the base film material and the reinforcing fibre element material. The one or more intermixed domains partially interrupt the direct interactions at the interface between the base film domain and the protrusion domain. Furthermore, the one or more intermixed domains have interfaces and direct interactions with the base film and protrusion domains. The average thickness of the base film is less than the average thickness of the fibre protrusion. The films of the invention have controllable physical and mechanical properties such as tensile strength, elongation at break, tear resistance, coefficient of friction and adhesion.

    Abstract: Improved reinforced thermoplastic resin, and devices and methods for producing the improved reinforced thermoplastic resin. The invention comprises complete fiber strand dispersion and wet out without breaking fiber filaments after cutting the fiber to a designated length. Certain embodiments of the present invention may comprise a zero-shear down screw which rotates very slowly. Thus, the resin and glass fiber bundles are slowly kneaded and the individual filaments unbundled from the fiber bundles resulting in complete wet-out of each filament without creating a pressure flow path for the substrate material and the entrained glass fibers and unbundled filaments. Optimized geometrically-controlled openings may be provided at the end of the down screw, providing further breakage-free kneading of the individual filaments. Certain embodiments may comprise an extended length cutting chamber which allow cutting very long individual fiber lengths. Temperature reduction mechanisms may be provided which provide a thermal block between the down screw assembly and the main frame assembly.

    Abstract: A flexible traction organ that can be wound and unwound, in particular for passenger and/or goods lifts, said organ comprising at least one stranded cable consisting of a tensile resistant material. The core strand of each stranded cable is surrounded by a flexible thermoplastic plastic layer. A production line for embedding several stranded cables in a flexible thermoplastic layer comprises a respective reel for unwinding the stranded cable, a device for accurately aligning the stranded cable, a heating element for pre-heating the stranded cable, at least one extruder for co-extruding the stranded cable in a flexible plastic sheathing, a cooling vat, a reel storage unit, a cutting unit and a reserve reel. The extruder, a wire guide and at least one die can be adjusted individually, conjointly and in relation to one another on a plane (P) that runs at an angle to the cable plane (E). The unwound stranded cables are degreased and/or pre-treated to improve the adhesion of the plastic sheathing, and pre-heated to a temperature of approximately ±20° C. in relation to the melting temperature of the flexible, thermoplastic plastic that surrounds the core strand and are sheathed with liquefied plastic in the extruder.
