Procedure for conforming couplings of hollow profiles (Machine-translation by Google Translate, not legally binding)

摘要

Method of forming hollow profile couplings, characterized in that the end of the profile of thermoplastic material subjected to deformation is heated to a temperature comprised between that of plasticization and fluidization; isolating the inside of said end of the rest of the profile by means of a plunger and a stopper, once said end is inserted in a mold corresponding to that of the coupling, and then injecting a fluid under pressure inside the sealed end.
