Abstract
An account is given of a process for making separate ornament stones with a heat-activated or thermoplastic adhesive coating, in the case of which a number of ornament stones are adhesively joined to a heat-activated adhesive foil and the single stones, with the heat-activated adhesive foil sticking to them, are freed from the compound structure made up of the separate stones and the foil. With this process single ornament stones may readily and simply be coated with a heat-activated adhesive of a true desired thickness where it is needed on the stones.
