Method of forming a spliced joint in a handrail or other elongate article
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.

METAL THERMOPLASTIC SANDWICH OVERMOLD
A metal and composite thermoplastic sandwich overmold adapted to achieve predetermined performance requirements without having to add metal and mass penalty to the assembly, and process to manufacture same. This is achievable by using the thermoplastic material that allows for a predetermined improved ribbing pattern that is connected to a base material. The ribbing can transfer load due to improved connection to the base material. There is provided increased plastic surface and edge encapsulation on the non-visible side of the part and the capability to provide well connected ribbing.
Method of bonding perfluoroelastomeric materials to a surface
The invention includes a method of bonding a perfluoroelastomer material to first surface that includes: (a) contacting a first surface with a bonding agent comprising a curable perfluoropolymer and a curing agent; (b) curing the bonding agent to form a perfluoroelastomer material that is bonded to the first surface. In the practice of such method, the bonding agent may be a solution prepared by dissolving the curable perfluoroelastomer and the curing agent in a solvent. In an embodiment of the invention, the perfluoroelastomer material formed in step (b) is a coating layer or, alternatively, the first surface is a surface of a perfluoroelastomer member and the perfluoroelastomer material formed is a perfluoroelastomer weld.
MOVING HANDRAIL AND METHOD OF MANUFACTURING MOVING HANDRAIL
Provided is a moving handrail that can lengthen its lifetime. The moving handrail includes: a handrail main body portion; a fabric arranged on a guide surface of the handrail main body portion and extending in a handrail longitudinal direction; and a resin sheet arranged on the fabric so that the fabric is sandwiched between the handrail main body portion and the resin sheet, wherein a surface of the fabric facing a handrail guide has arranged thereon an end portion of the fabric in the handrail longitudinal direction, and wherein the end portion of the fabric in the handrail longitudinal direction is covered with the resin sheet.

CUTTING WIRE FOR REMOVAL OF EXPANDED MATERIAL AFTER CURING OF A COMPOSITE PART
Composite fabrication system and associated methods. In one embodiment, a composite fabrication system comprises a molding tool that includes a forming surface at least partially disposed within a constrained space, and a foamable material that expands inside of the constrained space to form an expanded material that presses a layup of one or more composite layers against the molding tool. The composite fabrication system further comprises a curing device configured to cure the layup to form a composite part, and a cutting wire embedded in the constrained space that is heated and configured to cut the expanded material into pieces that are removable from the constrained space.
