Apparatus for the chemical metallization of open-pored foams, nonwovens, needle felts of plastic or textile material

Claim 1

Apparatus for the chemical metallization of previously activated porous substrate webs of foams, nonwovens, needle felts, plastic material or textile material, the webs having a porosity of 45 to 98% of the substrate material, comprising: a) a container for containing a chemical metallization solution and a substrate web; b) a movable device capable of carrying said container; c) a laying station in which a substrate web to be metallized is brought into contact with a chemical metallization solution by uniform laying in the container, the container being arranged on the movable device; d) a chemical metallization station into which the movable device carrying the container with the chemical metallization solution is introduced immediately after laying the substrate web in the container in the laying station and before initiation of a chemical metallization reaction, said chemical metallization station having a suction-removal apparatus for removal of gases and vapors produced during the chemical metallization reaction; e) a centrifugal station into which the movable device is moved and in which the chemically metallized substrate web is removed from the container with the chemical metallization solution immediately after being moved into the centrifugal station, said centrifugal station having means for centrifuging the chemically metallized substrate web that includes a centrifugal reel onto which said chemically metallized substrate web is wound, said centrifugal reel being rotatable such that still present excess chemical metallization solution is thrown off out of the pores of the chemically metallized substrate web upon rotation of the centrifugal reel.
