Abstract: Fire-protective strips, which foam above 150 degrees C in a fire, are sealed in by a process comprising (A) placing the strips longitudinally on a continuously guided flexible metal foil, which is coated on both sides with a hot-sealable polymer and which is 2-3 x as wide as the strip. (B) Stationary guide units wrap one laterally projecting metal foil part over the strip. The other projecting part is placed on top. (C) The wrapped strip is heated to hot sealing temp. (D) The 2 superimposed plastic-coated metal foil parts are firmly welded to one another by pressing. The strips are tightly sealed, without the formation of a projecting weld seam.

Abstract: The sealing in of fire-protective water-contg. alkali metal silicate strips comprises placing the strips longitudinally on a continuously conveyed flexible metal foil, coated on both sides with a hot-sealable plastics material. The foil is 2-3x wider than the strip. Fixed guide units are used to surround the strip first with one side of the projecting foil, while the other projecting side is placed on top of the first part. The surrounded strip is heated to hot-sealing temp. and the 2 superimposed parts of the plastics-coated metal foil are tightly welded to one another by pressing. Tight sealing-in of the fire-protective strip is achieved without the formation of a projecting weld seam.
