Title:
APPARATUS FOR FORMING CONTINUOUS BODY WITH HOLE
Document Type and Number:
WIPO Patent Application WO/1984/003726
Kind Code:
A1
Abstract:
Apparatus for forming a continuous body (98) which has at least one hole (99). The apparatus consists of a tubular member (13) of a cross-sectional configuration such that it defines the outer peripheral surface of the continuous body; a hole-forming member (15) which fits the hole; and a material-delivering means (27) which delivers a material (95) such as resin mortar which can be forced into the area between the tubular member and the hole-forming member, so that it sets there integrally. As the tubular member and the hole-forming member advance, a continuous body formed by the set material is left behind. At least the portion of the hole-forming member behind a predetermined position can be rotated by a driving device (18), to make it possible to prevent the material combining with the hole-forming member.
