Abstract

528,909. Moulding by extrusion. FIRESTONE TYRE & RUBBER CO., Ltd. May 4, 1939, No. 13359. Convention date, May 19, 1938. [Class 87 (ii)] Apparatus for moulding an article from heatsensitized latex comprises two metallic blocks having central apertures and chambers formed therein, means associated with the blocks for circulating fluids of controlled temperatures through the chambers, a housing extending through the central apertures in the blocks and spacing the blocks from one another, a mandrel secured in and spaced from at least a portion of the housing, and means for feeding latex between the mandrel and the housing whereby it can be coagulated by circulating a hot fluid through either one or both of the blocks. In the construction shown, a container 10 for latex is connected by a pipe 11 to a distributing tank 12 secured on a frame 13. Flow of latex from the tank is controlled by a valve 14 connected to a flexible conduit 15 leading to an adjustably mounted forming mould 16. The latex passing through the mould is cured in a tank 22 provided with steam-circulating pipes 23, 24, and is discharged by an endless conveyer 25 associated with steam pipes 28. The forming, mould 16 comprises two blocks 41, 42, Fig. 2, spaced apart and provided each with a central aperture 43 and a chamber 44. A housing 46 extends through the blocks and has a head 47 to which is secured the head of a mandrel 51. The mandrel has a tubular arm 53 concentric with and spaced from the inner wall of the housing 46. A second arm 54 is connected to the conduit 15 leading from the distributing tank. Cooling fluid is circulated through the chamber 44 in the block 41 and heating fluid is circulated through the chamber 44 in the block 42. , Specification 284,608, [Class 87 (ii)], is referred to.
