Abstract: A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.

Abstract: A handrail includes a carcass, a stretch inhibitor arranged within the carcass, a cover bonded to the carcass, and a sliding layer secured to the carcass. At a central width axis of the handrail, a face height between an upper exterior surface of the cover and a bottom surface of the sliding layer may be less than about 8.0 mm. The carcass may be formed of a first thermoplastic material, the cover may be formed of a second thermoplastic material, and the first thermoplastic material may be harder than the second thermoplastic material. The first thermoplastic material may have a modulus at 100% elongation of between 10 and 16 MPa, and may have a hardness of between 93 and 96 Shore A.

Abstract: A core mould element can be mounted between first and second mould parts. The first and second mould parts and the core mould element can be mounted between first and second thermal platens. The thermal platens can have generally planar faces for mounting in a press, for maintaining a desired pressure within the mould assembly. The thermal platens can provide for heating and cooling the mould assembly, and each can include a central portion and end portions, with thermal breaks between the central portion and the end portions. Bores can extend through the central and end portions, for receiving heating elements and pipes for cooling fluid. The end portions can include bores for a cooling fluid for cooling the end portions.

Abstract: In a handrail including a carcass, a stretch inhibitor within the carcass, and a sliding layer bonded to the carcass, at least a portion of the carcass has a gas phase dispersed in a solid polymer matrix. The gas phase can reduce a density of the carcass by at least 5% or 10%, or about 15%, as compared to a density of the polymer matrix. The carcass can have a generally uniform distribution of gas bubbles in the polymer matrix, which can define a generally closed cell structure in the polymer matrix. The gas phase can be formed of particles of a syntactic foam dispersed in the polymer matrix. The handrail can further include a cover. The carcass and the cover can be formed of thermoplastic materials, and the cover can represent between 10 and 30% of the overall TPU required for the handrail.

Abstract: A method of and apparatus for extruding an article of uniform cross-section, the article including a thermoplastic material and at least one cable for inhibiting stretch of the article. The cable is supplied to a respective tube and is conveyed between upstream and downstream ends. The thermoplastic material may be supplied to the downstream end of the tube. The thermoplastic material is brought together with the cable to embed the cable within the thermoplastic material, thereby forming a composite extrudate. The tube is configured to at least hinder movement of loose windings of the cable from the downstream end towards the upstream end, which may prevent or at least reduce incidence of “birdcaging”.

Abstract: A handrail has a thermoplastic body having a generally C-shaped cross section, a stretch inhibitor in the thermoplastic body above a T-shaped slot and a slider fabric layer. The handrail includes first and second end portions, each comprising a forward part extending from an end surface of the end portion and a rear part adjacent the forward part. A method of forming a joint can include: providing cuts to separate a top section of the thermoplastic body from a base section including shoulder portions; for each end portion, removing at least shoulder portions from the forward part thereof, to leave a central portion including a forward part at the slider fabric layer and a layer of thermoplastic; cutting the forward parts to a required shape; and assembling the first and second end portions together to form a spliced joint for moulding.
