...COOLING ON THE ...JOINT PART	F O R M I N G	C U R I N G

2. PURPOSE

2.1 Designed for Preventing Joint gauge unbalance, and maintaining joint ....tensile strength.

2.2 Effects on automobile inner tubes on joint part ;

(1) Decrease in the repairs caused joint bare.(productivity improvement).

(2) Improving looking quality and making out tube unbalance problem.

(3) Reducing an article of consumption cost.

.Lessening motor operating time. 111111111111111111111111111111111111111111111111

.Reducing Freon gas for cooling.111111111111111111111111111111111111111111111111

(4) Saving orginal cost from decreasing the disqualifications

3.Problem on technical development and method of ..improvement

(1) Causing many loss because of cooling joint part,

(2) The fatal factor- in the automobile inner tube manufacturing process, improving joint ....tensile strength is very important point.

(3) Direction of this tech development
