摘要： A rim rolling apparatus is provided having a plurality of rim rolling screws, a motor and a pneumatic cooling circuit. Each screw has a hot section and a cool section provided downstream of the hot section. The motor is configured to drive the screws in rotation to feed thermoformed articles between the screws to roll lips of the articles. The pneumatic cooling circuit extends within the screw from an exit end towards an entrance end. The cooling circuit is provided in thermally conductive relation with the cool section and insulated from the hot section.
