Title: An improved method of and apparatus for the molding of foam rubber products
Filed: 1953-08-24
Abstract: 726,508. Moulding foam rubber. TALALAY, A. Aug. 24, 1953 [March 6, 1953], No. 23315/53. Glass 87 (2) To facilitate detachment of the core pins 15 from the vulcanized foam rubber, the pins are coated with ice or frost 25 before they are immersed in the latex foam. After they have been immersed the foam is frozen to form a mass permeated by interstices, gelled by passing a coagulant, e.g. carbon dioxide, into the interstices, and vulcanized by heat. The heat melts the ice and makes the pins less tight or even loose. As shown, the mould parts 10, 11 are hollow and a refrigerant or cold brine is circulated through the hollow parts 22, 22a, the mould and pins being thus cooled to -30‹ C. If the surrounding atmosphere is wet enough, ice or frost will form on the pins ; if not, the pins are sprayed with a water mist. To facilitate transfer of cold from the mould 11 to the pins, the latter may be filled with cold liquid, e.g. brine. The invention may be applied to the process described in Specification 619,619, in which, inter alia, (a) the foamed latex is allowed to expand to 75 per cent. of the mould cavity volume before the mould is closed, and (b) tempering liquids are circulated through the hollow mould parts between the gelling and vulcanizing steps.

Abstract: 258,731. Austro-American Magnesite Co. (Osterreichisch - Amerikanische Magnesitges) Ges., and Erdmann, K. Sept. 19, 1925. Processes; endless-chain machines. -A process for manufacturing moulded articles from fibrous materials cemented together with Sorel cement, heat being applied, is characterised in that the binding and hardening of the mixture is effected without pressure in moulds which are surrounded by a medium, such as air, heated to 180‹-220‹ C. so that there is present a small quantity of the magnesium or zinc chloride or magnesium sulphate solution until the hardening is completed. The mixture of material to be moulded is composed, for example, of 100 parts by weight of wood fibre, 300 parts of calcined magnesia and 410 of magnesium chloride or magnesium sulphate solution at 28‹ BÚ. to ensure that a small quantity of the salt solution is retained until the hardening is completed. A moulding machine ior carrying out the process continuously comprises four steel conveying bands a which form a closed channel drawing the material in at one end and paying it out at the other as a moulded rope. The bands run endlessly over driving pulleys b and jockey pulleys c, and pass through a binding chamber e heated electrically or otherwise, where they are guided by rails f. The top and bottom bands overlap the side bands and the bottom band is of greater length than the others to receive the material from a shoot d. The issuing rope is carried by a series of rollers h and cut by a saw g in the usual manner.

In one embodiment, concave rolls 34, Fig. 4, are mounted on shafts 23 rotatably mounted on a fixed housing 31, there being a respective complementary convex roll 46 above each roll 34, rolls 46 being mounted on shafts 47 rotatable in a housing 41 also supporting conveyer rolls 42, the housing 41 being raised and lowered by a piston and cylinder device 45 assisted by counterweights 52. To allow compound bending of the glass sheets, the shafts 33, 47 are individually vertically adjustable. Each roll 34 or 46 is divided into segments 34a-34f, 46a-46f respectively, at least one segment, and preferably two symmetrical segments of each roll being keyed to its shaft to rotate with a peripheral speed equal to that of conveyer rolls 21, 42, 27, the other segments being free-running. The shafts 33, 47 and rolls 42 are all driven, via sprockets and chains, by one motor 30, a movable sprocket 81, Fig. 3, on a weighted lever 82 preventing slippage. The apparatus includes position-sensors and timers which operate so that the shaping rolls are held in engagement with the glass sheet for a period of time approximately equal to the time of a single revolution of the shafts 33, 47, to avoid introducing distortion resulting from changing the shape imparted by different rolls to the same increment of glass length. In a further embodiment, Figs. 11-19 (not shown), the conveyer rolls in the bending station are stationary vertically and level with the conveyer rolls in the furnace and cooler, and an upper and a lower set of shaping rolls are both moved vertically by pistons to engage a glass sheet, the conveyer rolls in the furnace being driven by a first motor at a slower speed than the conveyer rolls in the bending and cooling station s which, together with the shaping rolls, are all driven by a second motor. In another embodiments, rolls of an upper set of shaping rolls are concave and those of a lower set are convex. The conveyer rolls 21 in the furnace 22 are of stainless steel but conveyer rolls in the bending 24 and cooling section 26 are covered with fibre glass sleeves. Alternatively in the bending section, stainless steel maybe used and in the cooling section, mild steel. A gas heater may be used for conveying the glass sheets.
