Abstract
A tool for deep-drawing and sealing open plastics shells (3, 3') has a shell-like metal body (2, 2') which includes a flat edge (11, 11') at the open side. A heat insulating attachment is secured to the edge of the metal body so that the outer seam of a first plastic shell can be joined by sealing, to the outer seam of a second plastic shell oppositely disposed to it without supplying additional heat.
