Title:
MANUFACTURING METHOD OF EXPANSION TYPE RAFT
Document Type and Number:
Japanese Patent JPS5923796
Kind Code:
A
Abstract:

PURPOSE: To perform a work in a good work environment and reduce production time by using heat fusion type adhesive whose principal component is polyamide resin.

CONSTITUTION: Heat fusion type adhesive 6 molded in a sheet form is inserted in the adhesion section of a rubberized fabric 4 cut in a specified shape. Molds 11a and 11b are heated by a heater 10 and thus heated molds 11a and 11b are presscontacted on the rubberized fabric 4 by a pressure device 12 and heat- pressed. Then, molds 13a and 13b at a normal temperature are cooled by the pressing device 12 while they are being press-contacted on the rubberized fabric 4. At this time, full adhesion strength can be obtained. Besides, the butt sections of both a main air chamber and a stay air chamber are bonded in this method.
