Abstract

A device and method of shaping the visors of caps is disclosed. In the device, a visor shaping unit has a movable upper mold and a fixed lower mold. The upper mold, with a coil heater, is outwardly curved into a predetermined curvature at its lower surface and is operated by a hydraulic cylinder. The lower mold is inwardly curved into the same curvature as that of the upper mold at the top surface. The cooling unit has first to third chambers with a plurality of perforated sections being formed on the top wall of each of the chambers. Upper and lower panels are exteriorly attached to the top wall of each chamber at a position covering each perforated section. The two panels define a curved gap between them, thus holding a heated visor in the gap during a cooling process. The visors are heated at about 90.degree. C. to 150.degree. C. for about 5-20 seconds in the visor shaping unit prior to being cooled in the cooling unit for about 10-30 seconds using cool air having a temperature of about 5-20.degree. C. The curved configuration of the visors, shaped by the device and method of this invention, is maintained almost permanently.
