Abstract
305,531. Goodyear Tire & Rubber Co., (Assignees of Andrews, G. G.). Feb. 6, 1928, [Convention date]. Cleaning - apparatus. -Rubber moulds are cleaned by immersion in an alkaline solution under heat and pressure or heat alone. A pair of vessels 11 are employed which are connected by a pipe 12 fitted with a valve 13 and an exhaust valve 35. Each vessel is furnished with a steam jacket 22 and with a removable cover 33 adapted to be secured by lugs. In use, a mould 41 is placed in the bottom of the vessel and covered with cleaning solution 40, after which the cover 33 is secured in position and steam is circulated through the jacket 22 to vaporize the solution. After treatment, the valve 13 is opened to permit the solution to pass to the other vessel; this operation may be assisted by steam admitted through a pipe 27. Suitable materials for the cleaning solution are potassium and sodium hydroxide or sulphide, e.g. sodium hydroxide of 10-15 per cent strength employing a steam pressure of about 80 lbs. per sq. in.
