ABSTRACT:
A filter support tube manufacturing apparatus and method employing operative steps of drawing wire from a reel, and moving the wire, first, through a heater for heating the wire, second, through a fluidized bed for coating the wire with a corrosion resistant material which also serves as a bonding agent and, third, through a second heater. Then, the heated and coated wire is wound onto a rotating mandrel which holds straight plastic reinforcing strips about which the wire is wound. Once winding of the wire is completed and the wire is embedded in the plastic reinforcing strips, the wound wire is cut manually and removed from the mandrel. A new end of the wire extending from the reel is inserted in the mandrel and a new set of plastic strips are installed on the mandrel. Finally, the steps are repeated to make additional filter support tubes.
