摘要

The foil ring possesses a foamed body (2) with a moulded-on flange (3), in which a flexible foil (1) is foamed in certain regions. Distance pieces (5), which are distributed over the periphery of the flange (3) and which anchor the foil (1) in the body (2) and position the foil (1) during manufacture, are likewise foamed in. The foil ring can be used, for example, for a drainpipe for floor or roof drainage, or for a pipe connection. IMAGE
