Abstract
There are adhesive foams that are formulated for gun uses and adhesive foams that are formulated for adapter use. This means a double track in production, storage and use of adapter foams. The invention is a gun version that permits use of adhesive foams such as used in the adapter version. For this purpose, the needle and the nozzle tube in the gun have a shape such that the nozzle tube has at least one mixing path, and the amount of foam can be sensitively metered by means of narrowings and widenings between the inner wall of the nozzle tube and the outer wall of the needle.
