发明名称 Splicing methods for an extruded handrail
摘要 A method of splicing a length of extruded handrail having a C-shaped cross-sectional configuration, a substantially flat inner drive surface, and a plurality of spaced, longitudinally extending inextensible members embedded in the body of the handrail. The ends of the handrail are squared, aligned, and butted. Longitudinally extending grooves are cut into the flat drive surface, through and on both sides of the butt joint, in the spaces between the embedded inextensible members. Predetermined lengths of inextensible members and elastomeric material are placed in the grooves, and bonded to the surfaces which define the grooves. In another embodiment, the grooves are extruded into the flat drive surface at the same time the handrail is extruded. In either embodiment, the ends of the handrail may be bonded together prior to, or simultaneously with, the bonding of the inextensible members and elastomeric material with the groove surfaces.
