MANUFACTURING METHOD FOR BUILDING HANDRAIL

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for a building handrail, which is produced by successively coveringly laminating a non-rigid synthetic resin layer and a skin synthetic resin onto the outer periphery of a core material made of metal or the like. SOLUTION: After covering a running core material 2 under the state being passed through a mold die 8 with a synthetic resin having a JIS A hardness of 85 or less or a non-rigid synthetic resin foam made of the synthetic resin poured in a first extrusion molding machine and then coveringly laminating the outer periphery of the non-rigid synthetic resin with a strong synthetic resin having a JIS A hardness of 90 or less poured in a second extrusion molding machine 7 by a thickness of 0.2 mm or less, the resultant core material is cut off into required dimensions after being solidified in a cooling water tank 9.
