Abstract

Thermoforming machine (10) for shaping, filling and closing cups (3), which has a heating station (12) with pairs of heating plates (18, 18a, 19, 19a) movable towards each other for a continuous sheet (2) thermoformable. To make both the bottom (6) of the glass (3) and its side wall (7) have approximately the same wall thickness, the last two heating plates (18, 19), seen in the direction of transport of the continuous sheet (2), have areas (21, 22, 23) that are spaced differently in relation to the continuous sheet (2). Due to this, when the two heating plates (18, 19) move towards each other, material from the continuous sheet (2) moves to the area of the side wall (7) to be formed, while the area is thinned. of the bottom (6) to conform.
