Title: A process for the production of foam rubber
IPC: C08J9/14
Filed: 1966-06-29
Abstract: Foam rubber is obtained by a process in which a rubber composition containing a liquid organic blowing agent and a vulcanizing agent is foamed by the evaporation of the blowing agent and is vulcanized, the moment of reaching the greatest expansion of the rubber composition as a result of the complete evaporation of the blowing agent substantially coinciding with the beginning of the vuclanization reaction.  Preferably the greatest expansion is reacted at a time very close to that at which the scorch time of the rubber composition elapses.  Suitable rubbers are butadiene, styrene/butadiene, and isoprene rubber. Suitable blowing agents are hydrocarbons, halohydrocarbons, alcohols, ketones and esters.  The rubber composition used in Example 8 includes styrene/butadiene rubber, zinc oxide, stearic acid, an anti-oxidant, polyethylene glycol, aluminium silicate, processing oil, sulphur, N-oxydiethylene-2-benzothiazole-sulphenamide, a mixture of 2-mercapto benzothiazole and a dithiocarbamate, and xylene as a blowing agent. The rubber composition may be extruded and the extrudate foamed and vulcanized in an oven or the extrudate may foam as it leaves the die and only vulcanization takes place in an oven.  The blowing agent may be injected into the rubbery mass in the extruder.

Abstract: 363,731. Chenille. MORTON, J., Craigiehall, Cramond Bridge, West Lothian. Oct. 1, 1930, No. 29365. [Class 142 (iv).] Chenille is formed by supplying a series of pile-threads to a web of binding threads or tapes, which have been previously coated with adhesive, and pressing the former on to the latter, the fabric thus formed being subsequently cut into strips of fur, in each of which the binding thread forms the core. The binding threads B, Fig. 1, are drawn from a beam 52 or other supply, between adhesive applying rollers 11, 12, and thence under a roller 13 to a steamheated drum 10 around which they are guided by annular grooves 17, Fig. 2. The drum is intermittently rotated by Geneva-wheel and bevelgear mechanism from the shaft 25 and after each movement a pair of curved grippers 60, 61 are actuated to grip the yarn protruding from a series of carriers 110, such as those described in Specification 323,260, [Class 142 (iv), Woven fabrics &c.], and pull a supply of pile yarn across the drum and over the binders. The yarn thus positioned is cut off from the supply by knives mounted by the side of the drum and is caused to adhere to the binders by the pressure of a curved block 14 operated by a cam 37a on a shaft 37 which is driven by bevel gearing from the shaft 25. The grippers, which are in the form of curved combs, are carried by frames 62 slidably mounted on shafts 63 which are rotated in opposite directions alternately by a cam-operated rack 78, the transverse movement being effected by. connecting the frames 62 to chains associated with sprockets 98 on a shaft 97 which is operated by a cam-operated rack 94. The preparatory cloth thus formed is held in contact with the heated drum, as the latter rotates, by steel bands 15 mounted on an assembly of rollers 40 ..43, which may be formed with grooves to accommodate the bands and keep them in position. Cutting means 16 comprising a series of disc knives, operated from the shaft 25, may be interposed to cut the fabric into strips of chenille which may be stored in any suitable way or the apparatus may be used solely for producing a preparatory cloth, the cutting of which may be conducted as a subsequent operation. In a modification the drum 10 is rotated during the pressing operation and the pile yarns are caused to adhere to the tapes by means of pressure rollers or the latter may be used in conjuction with a stationary heated table. The binding threads may be applied at both sides of the preparatory cloth.
