Abstract

1,212,402. Continuously forming articles of foamed plastics. SOC. FLANDERS INDUSTRIE, B. M. J. DEGARNIER DES GARETS and X. E. J. MALBRANQUE. 7 March, 1968 [9 March, 1967; 4 March, 1968], No. 11147/68. Heading B5A. Apparatus for continuously manufacturing sheaths and section members of expanded synthetic plastics material coated with a sheet material on the outside comprises an elongated outer tubular member 1 consisting of two halfcylinders mounted in a frame 2, reels such as 10 and 11 and 14, 15 and 16 (not shown) supplying coating film 12 to the inside of the tubular member 1, two injectors 20 and 21 for injecting the components required to form a rigid polyurethane foam into the annular space 6 in tubular member 1, and driving means generating a continuous longitudinal sliding movement between the tubular member 1 and the coating material 12 containing the polyurethane foam. The former 3 which may be a temporary or permanent framework slides freely inside the tubular member 1 and moves forward as the foaming material is delivered on to it by the injectors 20 and 21. As the coating film 12 is supplied its selvedges are joined to form a tubular member by welding, adhesion or by means of a sliding fastener having a slider connected to the tubular member 1. The driving means comprises a motor and four bi-conical rollers two of which 52 and 53 are supporting driven rollers and two of which 54 and 55 are guide rollers. Arms such as 524 and 544 connected to rollers 52 and 54 are connected to the same stirrup 56 biased by an adjustable spring 57. Diameter selectors such as 543 regulate the force with which the rollers grip the pipe. The machine may be used in the field for laying pipes directly into trenches.
