| abstract | 653,006. Rubber thread. ANDREWSALDERFER PROCESSING CO., Inc. March 6, 1948, No. 7005. Convention date, July 30, 1947. [Class 70] Rubber thread is obtained by cutting a sheet of uncured rubber stock into a multiplicity of threads, stretching the threads, adhering them to a moving surface, permitting the threads to relax to remove internal stress, while the threads are adhering to the surface, and curing the relaxed threads without removing them from said surface. In a preferred method a stock made from rubber, GR-S, antioxidant, softener, zinc sulphide, zinc oxide, diphenyl guanidine, and either dipentamethylene thiuram tetrasulphide or a mixture of sulphur, the zinc salt of mercaptobenzthiazole, and tetramethyl thiuram monosulphide is formed into sheets 1 (Fig. 1) and passed through a splicing-machine 5, and then over supporting roll 12 and under roll 13 which is submerged in a bath 14. This bath preferably contains a soap solution which facilitates the cutting by knives 16. The separate threads now pass into bath 20 which preferably contains a water-soluble accelerator such as piperidinium pentamethylene dithiocarbamate or butyl zimate or dibutyl ammonium oleate and then into bath 27 which contains a wax solution preferably containing carnauba wax. The stretched and coated threads pass on to belt 30 to which they adhere and then pass through vulcanizing chamber 32 (Fig. 1A) in which the threads are cured. The threads are then stripped off the vulcanizing belts by rolls 35 and 36 and after passing through soap-storing box 38 passes to the packaging stage. |
