Abstract
(EN)
A method for manufacturing a belt comprises: preparing a metal cylindrical mold (43), a cylindrical molding body (36), a rotating mechanism (41) that rotatably supports the cylindrical mold (43), and electromagnetic induction coils (47a, 47b, 47c) that heat the cylindrical mold (43) by means of electromagnetic induction heating; arranging the molding body (36) inside the cylindrical mold (43); and, with the molding body (36) being pressed from the inside while the cylindrical mold (43) is being rotated by the rotating mechanism (41), molding a cylindrical belt slab (S) by heating the molding body (36) by means of the electromagnetic induction coils (47a, 47b, 47c) and pressing the same toward the cylindrical mold (43).
(FR)
La présente invention concerne un procédé de fabrication d'une courroie consistant à : préparer un moule cylindrique métallique (43), un corps de moulage cylindrique (36), un mécanisme rotatif (41) qui supporte de manière rotative le moule cylindrique (43), et des bobines d'induction électromagnétiques (47a, 47b, 47c) qui chauffent le moule cylindrique (43) au moyen d'un chauffage par induction électromagnétique ; agencer le corps de moulage (36) à l'intérieur du moule cylindrique (43) ; et, le corps de moulage (36) étant pressé depuis l'intérieur tandis que le moule cylindrique (43) est tourné par le mécanisme de rotation (41), mouler un bloc de courroie cylindrique (S) en chauffant le corps de moulage (36) au moyen des bobines d'induction électromagnétiques (47a, 47b, 47c) et en les pressant vers le moule cylindrique (43).
