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.
