Abstract

1321223 Extruding reinforced tube CREATORS Ltd 16 Sept 1970 [16 June 1969] 30463/69 Heading B5A [Also in Division F2] A reinforced plastics tube comprises an extruded tube 1 of a first plastics e.g. of flexible P.V.C., externally reinforced by a mesh 2 of a second plastics material e.g. rigid or semi-rigid P.V.C. or nylon, which has been extruded with the strands thereof integral at their crossing points. The mesh 2 may be bonded to the tube 1 either under heat and pressure and/or by adhesive. The net 2 may be embedded in the tube 1 and the reinforced tube may be enclosed in an outer extruded sheath preferably compatible with, and bonded to, the outer surfaces of the tube 1 and mesh 2. In the described embodiment, the tube 1 and mesh 2 are simultaneously extruded respectively through a tube die outlet supplied from a first extruder 12, and through a die outlet concentric therewith and comprising a plurality of orifices 15 disposed on a circular path and each being defined by half sections in each of outer die member 14 and an inner die member 13 which produce the integral net structure by relative rotation, or by the oscillation of both or one thereof e.g. by a crank cam 17, through a relative distance of one circumferential pitch of the mesh aperture, the net 2 being bonded to and partially embedded in the surface of the tube 1 by passage through a water cooled vacuum sizing die (not shown). The outer member 11 of the tube die outlet may also be rotated or oscillated. The mesh size and pattern may be varied by the size and disposition of the extrusion apertures thereof and the frequency of oscillation of the elements 14 and/or 13 relative to the extrusion speed of the tube 1.
