(54) STAMPING DEVICE
by vulcanization is fixed in the upper part of the elastic medium.
In the bottom plate 3, a groove is made into which the walls 6 of the container enter when it is lowered. The groove is a guide for the walls, and the outer walls of the groove support the walls of the container during the compression of the elastic medium. The gap between the plate 3 and the walls 6 in the closed position of the container is closed by the stripes 13 arranged along the perimeter of the elastic medium. The direction of the walls 6 of the container is provided besides the groove guide plates 14 and 15, which are fixed to the fixed plate 3.
Support plates 1 and 2 are in contact with plates 3 and 5 installed on them, respectively, not over the whole area, but only along the periphery. The gap 16 between these parts can be provided by making their support surfaces concave.
