Abstract

1479000 Moulding and perforating pipes H-J BAAR 16 Oct 1974 [16 Oct 1973] 44902/74 Heading B5A [Also in Division F2] Relates to a corrugated plastics drainage pipe (see Division F2). A corrugated plastics pipe 1 is formed by passing flat unhardened extruded tube 1 into a mould comprising two endless open-link chains 8, 8<SP>1</SP>, having moulding links 9 each enclosing one half of the pipe circumference. As the flat pipe 1 is fed into the moulding region over guide bar 10, air blown through openings 13 forces the unhardened pipe 1 against the corrugated inner surface of the links 9. Links 9a spaced around endless chains 8, 8<SP>1</SP> co-operate in the moulding region to form annular channel 4, which when in engagement with openings 18, fed by air via inner pipe 14, and vacuum connections 19 has intake openings formed therein. Indentations only may be formed in the annular channel 4 which are subsequently opened out into intake openings after hardening of pipe 1.
