Title: Improvements in or relating to patterned material of rubber or containing rubber as its principal constituent and the manufacture thereof
IPC: B29C37/00
Filed: 1930-06-27
Abstract: 356,849. Rubber floor - coverings. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, and WARREN, F. W., 2, Cambridge Street, Manchester. June 27, 1930, No. 19624. [Class 140.] In making patterned material of or containing rubber, such as floor-coverings, which comprises a backing of fabric and rubber to which pattern components are applied and vulcanized thereon, the pattern components are produced from rubber or rubber compound which is devoid of vulcanizing agents such as sulphur, and either an excess quantity of vulcanizing agent is incorporated in the backing, or the vulcanizing agent is subsequently applied superficially to the pattern components when assembled on the base. Accelerators may also be applied. By this process the rejected parts or waste of the coloured rubber sheets from which the pattern components are cut may be returned to the sheeting mills without becoming wholly or partially vulcanized. The general arrangement of the plant is shown in the Figure. Rubber compound of different colours is sheeted in mills 2. Each sheet is fed to a cutting-out apparatus 6 which cuts out portions of the sheet to form the pattern components and deposits these on a backing 3 which preferably comprises rubber-coated canvas or similar fabric. The cutting-out apparatus is of the type commonly used in the making of inlaid linoleum. The parts of the sheets not used are removed by brushes 9. The assembled material passes over rollers 10 to an inspection roller 11, and thence to pressing means comprising rollers 14, 17 and a rubber belt 15. The material is then passed around heating rollers 18, 19, 20, where it is vulcanized. The apparatus described in Specification 319,448, [Class 70, Indiarubber &c.], may be used in this operation. In the application of the invention, the sulphur for vulcanizing the material is carried by the backing 3 as a constituent of the rubber mix applied thereto. Migration of the sulphur to the pattern components takes place during vulcanization. When the amount of sulphur in the base is normal, the sulphur for vulcanization, with or without accelerators, is applied by means of a roller located between the pressure band 15 and the drum 18.

[Class 23] The concentric skimming devices 9, 13 discharging two liquids separated in a centrifugal bowl, are arranged in two chambers separated by a partition 18 with a central aperture. To prevent the separated liquids from re-mixing across the aperture, channels 6 are provided in the upper skimmer 13 so that the central space 30 is in communication with the outside air through the channels 6 and the central space of the cover. Similar channels 5 may be made in the lower skimmer 9 so that the spaces 30, 3, are in communication through the channels 5 and the vent 4. The mixture is admitted through the feed pipe 1 and the separated constituents are discharged through the skimmers 9, 13 to pipes 15, 16 with regulating valves. In a modification the feed pipe passes downwards centrally through the skimmers. In another modification the channels 6 are replaced by a passage 25 through the partition 18 and the bowl cover. In addition channels 28 may be provided with adjustable nipples the inner orifices of which are at a greater distance from the axis than the inner edge of the partition. Liquids will then be discharged through the nipples before the constituents can mix.
