Machine pressing thermoforming sheet to make containers, ensures sheet first contacts heated molding surfaces to avoid excessive localized thick-setting and to enhance wall thickness uniformity, cooling only subsequently
At the pressing station (14) a heater is included, at least for regions of the molding recesses (24) first coming into contact with the thermoforming band (2). Preferred features: The molding station includes an upper section (21) and a lower section with molding recesses (24) facing it. The entire lower section is heated. A cooling station (15) immediately follows the molding station. Its upper and lower sections (31, 29) close together. The container molded (6) can be picked up or accommodated with a degree of interlocking, in the upper or the lower section. The lower section has cooling recesses (32), interlocking with and accommodating the container.
