Abstract

See full text

A thermoforming device according to the present invention has a masking plate and a heater block. A plurality of the heater blocks are disposed with a space therebetween in a planar direction of the masking plate. The thickness of the masking plate is 0.2-3.0 mm. The distance of the space is 1-15 mm, and the distance of the space is set at least five times larger than the thickness of the masking plate. Heat to be transmitted to the masking plate from a high temperature heater block is more easily transmitted in the thickness direction of the masking plate than in the surface direction of the masking plate, and is more easily transmitted to the sheet than to a portion, of the masking plate, corresponding to a low temperature heater block, whereby a temperature difference is provided between different zones of the masking plate.
