HEATING, PRESSURIZING AND WELDING STRUCTURE AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide such a structure that does not require continuous supply of a functional oil of a rather high concn. as a removing agent to the heating, pressurizing and welding device and that the required releasing performance can be obtd. at a low cost. SOLUTION: In this structure 10, a functional removing agent 24 having functional chains of rather high concn. (about 0.05 to 0.3 mol.%) is supplied to an elastomer welding member 12 by a first RAM (releasing agent managing) system 26. Then, a releasing agent having of low functional property or no functional property is supplied by a second RAM system 44. The first agent is periodically supplied while the second agent is continuously supplied. The periodical supply of the high concn. releasing agent 24 includes a rather short time of supply when the machine is started and the succeeding periodical supply as required.
