まう。2. Description of the Related Art A thermoforming machine of this type is known, for example, from German Utility Model 70 37 886. When producing cup-shaped containers from heat-deformable strips, the problem arises that the bottom of the container generally has a significantly greater thickness than its side walls. This is due to the fact that the heated strip is most significantly deformed and stretched in the region of the side walls during deep drawing. Therefore, a relatively thick strip is required to provide sufficient strength in the region of the container sidewall, but the region at the bottom of the container is:
It has a large thickness that is not required for strength reasons.

2, the belt-shaped sheet 2 is first conveyed between the heating plates 18a and 19a and finally conveyed between the heating plates 18 and 19 (FIG. 2). In that case,
The heating plates 18 and 19 are moved to face each other at the stage of stopping the belt-like sheet 2, and the belt-like sheet 2 already heated by the heating plates 18a and 19a is plastically deformed under the action of heat and pressure. (FIG. 3). In this case, a thinned region 24 is formed in the band-shaped sheet 2 in the range of the first contact region 21, and the thinned region 24 is formed in the bottom portion 6 during the deep drawing forming process which is continuously performed in the forming device 13.
Is formed (FIG. 4). On the other hand, in the other two contact areas 22 and 23, a thickened area 25 is formed in the band-shaped sheet 2, and from the thickened area 25, particularly in the deep drawing, the area of the side wall 7 of the cup 3 is formed. You. This thickened region 25
Material accumulation occurs in the thickened region 2
5 is provided with a portion having a thickness larger than the thickness of the first belt-shaped sheet 2. This material is used for both heating plates 18, 19
Are pressed from the thinned region 24 to the thickened region 25 when they are pressed against each other.

領域２４が設けられている。By forming the thinned region 24 and the thickened region 25 in the belt-shaped sheet 2, the deep-drawn cups 3 can have the bottom portion 6, the side wall 7 and the flange 7 all having at least substantially the same thickness. 8 and so on. This means that, during deep drawing, the area of the side wall 7 is deformed and stretched most significantly, but in this area, due to the thickened area 25, most material is provided for deformation. Due to that. On the other hand, in particular, the bottom portion 6 is formed from a region of the strip-shaped sheet 2 which is deformed and stretched only slightly, that is, a region which is least affected by deformation and stretching. Therefore, a thinned region 24 is provided to form the bottom 6.

22, 23 can be adapted to the shape of the container to be molded. In short, if the bottom shape and the side wall shape of the container are different, the contact areas 21, 22, 23 also have different shapes. It is only important for the invention that the material is pushed out of the thermoplastically deformable strip from the least deformed and stretched areas during the subsequent forming process into the more deformed and stretched areas. It is in. This is effected by correspondingly configured heating plates 18, 19 which are arranged in the heating device 12 in addition to the flat heating plates 18a, 19a. Depending on the application, it is also conceivable to form the heating device 12 without the flat heating plates 18a, 19a. In that case, only the structured heating plates 18, 19 are present. This means
For example, this is conceivable when only a small amount of heat is required for plastic deformation of the belt-shaped sheet 2.

That is, in this case, the unheated plate merely serves as a counterholder for the heated plate. Furthermore, one plate may be formed as a flat plate and the other plate may have contact areas raised at different heights.
