CA 2221524

A method and device for shaping the visors of caps is disclosed. In the method, the visor is curved into a predetermined curvature prior to being heated by hot steam having a temperature of about 100 °C for about 5 - 150 seconds. The heated visor is cooled by a cool air current having a temperature of about 5 - 25 °C for about 10 - 150 seconds. The device has heating and cooling units respectively connected to hot steam and cool air sources. A plurality of molds, used for shaping the visors, are received in at least one of the two units. Each of the molds includes two perforated panels, which are curved into the curvature and are assembled into a single body, with a plurality of spacers being interposed between the two panels and spacing the two panels apart from each other while defining a curved gap between the two panels for receiving the visor of a cap.

Méthode et dispositif servant à former des visières de casquettes. Selon cette méthode, la visière est courbée dans une forme à courbure prédéterminée avant d'être chauffée à la vapeur à une température d'environ 100 degrés Celsius, pour une période de 5 à 150 secondes. La visière chauffée est refroidie par un courant d'air frais, à une température d'environ 5 à 25 degrés Celsius, pour une période de 10 à 15 secondes. Le dispositif est doté d'unités de chauffage et de refroidissement reliées respectivement à une source de vapeur chaude et à une source d'air frais. Plusieurs formes servant à courber les visières sont logées dans au moins une des deux unités. Chacune des formes est composée de deux panneaux perforés courbés dans la forme courbe, qui sont assemblés de manière à former une seule pièce, plusieurs éléments d'espacement étant placés entre les deux panneaux pour les maintenir espacés tout en décrivant un espace courbe entre les deux panneaux, où s'insère la visière à former.
