ABSTRACT:
An apparatus for forming flexible tubing wherein the apparatus provides a tube-forming mandrel adapted to form a continuous, reinforced, flexible tube from an indefinite length of a tape or ribbon of flexible material, together with an indefinite length of wire, which are wound and bonded together to form the tube. The mandrel includes a plurality of angularly disposed cylindrical rollers which are rotatably positioned adjacent each other, each roller being fixed at a given angular displacement with respect to the other and to the central axis of the mandrel, in order to establish the fixed skewed arrangement of a plurality of annular grooves formed in each roller, so as to allow the forming tube to advance axially along the rollers. The rollers are journaled at one end to a support plate and at the opposite end to a truss plate, the support plate and the truss plate being fixedly connected together by a centrally positioned mainstay, so as to establish the fixed skewed arrangement of the rollers and their associated annular grooves.
