Connection method of thermoplastic resin long body

Abstract

A connection method for interconnecting end portions of a thermoplastic resin long body in which conductive unstretchable members are embedded within the thermoplastic resin along a longitudinal direction, wherein the unstretchable members in each of specific sections in the both end portions of the thermoplastic resin long body are heated using an induction heating portion so that the thermoplastic resin coating the unstretchable members is removed by melting for the unstretchable members to be exposed, after which the both end portions are interconnected while they are held in a state where the unstretchable members being exposed in the respective end portions are butt-connected to each other.

1 . A connection method of a thermoplastic resin long body for interconnecting end portions of a long body made of thermoplastic resin in which conductive substantially unstretchable members are embedded within the thermoplastic resin along a longitudinal direction, the method comprising:
 heating the unstretchable members in each of specific sections in both end portions of the thermoplastic resin long body using an induction heating portion;   exposing the unstretchable member by removing the thermoplastic resin coating the unstretchable members interconnecting, the both end portions while the both end portions are held in a state where the unstretchable members have been exposed in one end portion and in the other end portion and are butt-connected to each other.   
     
     
         2 . The connection method of a thermoplastic resin long body according to  claim 1 , further comprising:
 controlling a temperature of the unstretchable members heated by the induction heating portion so as to be maintained at a constant temperature or in a predetermined temperature pattern.   
     
     
         3 . The connection method of a thermoplastic resin long body according to  claim 1 , further comprising:
 controlling a hardness of the thermoplastic resin that is softened due to an influence of the unstretchable members heated by the induction heating portion is at a predetermined value.   
     
     
         4 . The connection method of a thermoplastic resin long body according to  claim 1 , further comprising:
 physically connecting the unstretchable members that are exposed in the one end portion and in the other end portion to each other.   
     
     
         5 . The connection method of a thermoplastic resin long body according to  claim 4 , further comprising:
 heating the unstretchable members being exposed in the one end portion and in the other end portion by induction heating while the end portions are physically connected to each other.   
     
     
         6 . The connection method of a thermoplastic resin long body according to  claim 4 , further comprising:
 connecting the unstretchable members being exposed in the one end portion and in the other end portion to each other using a connection supporting member.   
     
     
         7 . The connection method of a thermoplastic resin long body according to  claim 1 , wherein:
 the unstretchable members are a plurality of long slender copper cables.   
     
     
         8 . The connection method of a thermoplastic resin long body according to  claim 1 , wherein:
 the thermoplastic resin long body is a moving handrail of one of a passenger conveyer and an escalator.
