Abstract
A method of making a filtercloth which includes fixing components to the cloth includes the use of a thermoplastic bonding agent mixed with a ferrous metal powder. The bonding agent is induction heated to fuse the parts together, using the metal as a susceptor. FIG. 3a is a section through a typical assembly being bonded.
Claims1
A method of making a filter including the steps of bonding two pieces of cloth to the flanges of a flanged tube by locating an annular piece comprising a thermoplastic bonding agent mixed with a ferrous metal powder between each flange and the adjacent surface of the cloth and then using induction heating to heat the ferrous metal powder and thus cause the bonding agent to bond the cloth to the flanges.
