Title:
MANUFACTURE OF HOSE WITH PROTECTOR AND MATERIAL ASSEMBLING APPARATUS USED FOR IT
Document Type and Number:
Japanese Patent JP3669087
Kind Code:
B
Abstract:

PROBLEM TO BE SOLVED: To easily insert a protector material into a hose material and to eliminate positional deviation of the both from one another with satisfactory shape.
SOLUTION: The air is supplied from an end of a base end 23a of a hose inserting member 23 in which an unvulcanized rubber hose material H is inserted via an air passage hole 23e, a thin rubber tube 23c covering an extended part 23b is bulged, and held so that the rubber hose is not moved to the inserting member. An unvulcanized protector material P is inserted into a protector inserting member 33, a protector radially enlarging member 36 is inserted into a central space, and the protector inserting member is radially urged to be radially enlarged. Thus, the material P is radially enlarged so that its inner diameter becomes larger than an outer diameter of the rubber hose material. The material P can be inserted so as not to positionally deviate to a predetermined position of the hose material by a protector inserting unit 40 and so as to eliminate outer diameter enlargement or waviness due to contraction of the hose material.
