The band (1) acts as a seal, and is moulded from an elastomeric, or elastic rubber, material. It is in the form of a strand, which has one or more strips (5), which are at least partly embedded in it. Each strip is made from a material which can be welded, and is especially a thermoplastic, and may be made from a polymeric material, which can also be welded to itself. At least two strips may be embedded into the band, and these may also be polyvinyl chloride, while the sealing band (4) is made from a soft elastic material. A reinforcing band (6) made from a hard elastic material may also be connected in parallel with it. |
