APPARATUS FOR MOLDING COLUMNAR PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for molding a columnar product capable of manufacturing the product heretofore limited in manufacture by rapidly feeding a belt member while considering a production and circumferential environment together with a safety and simultaneously manufacturing the product of a high quality. SOLUTION: In the apparatus for centrifugally molding a solidifiable fluid in a form or a steel tube pile in a columnar state by imparting a rotation to the form or the steel tube pipe by a belt-like member, the columnar product is constituted so that a holding angle of the form or the pipe by the belt-like member becomes 50 to 80 deg. as seen from a rotary axial direction of the form or the pipe. Or, in the same apparatus with a constitution in which the belt-like member is fed via at least two pulleys of the apparatus, at least a distance between shortest positions of a pair of pulleys to support the form or the pipe is 1.2 or 2.0 times as large as a diameter of the form or the pipe.
