Title (EN) APPARATUS FOR MAKING ELECTROFUSION SADDLE COUPLER INCLUDING HEAT GROOVING AND WIRE INSERTION DEVICES
(FR) RACCORD CONCAVE D'ELECTROFUSION ET PROCEDE ET APPAREILS POUR LA FABRICATION DE RACCORDS CONCAVES D'ELECTROFUSION
Abstract:
(EN) (57) Abstract An apparatus for forming electrofusion saddle couplers includes a first longitudinally movable rotatable arm (24), a second rotatable arm (32) movable perpendicularly to the first arm, and an operating head (42) attached to the second arm which includes a laser-heated heat grooving device for creating a groove in the saddle coupler and a wire inserting device for inserting a resistance heating wire (21) into the groove (46).
(FR) Procédé et appareils pour noyer un fil de chauffage ohmique dans un élément thermoplastique présentant une surface, par exemple un raccord concave d'électrofusion. Le procédé consiste à utiliser une tête de travail comprenant des moyens de rainurage thermique et des moyens d'introduction d'un fil, la tête de travail et l'élément thermoplastique étant montés mobiles dans tous les sens l'un par rapport à l'autre; à utiliser les moyens de rainurage thermique et le déplacement relatif pour former une rainure dans la surface de l'élément thermoplastique; puis à utiliser les moyens d'introduction et le déplacement relatif pour introduire le fil de chauffage ohmique dans la rainure afin de l'implanter dans celle-ci.
