METHOD OF AND DEVICE FOR REPROCESSING OF RUBBER CONTAINING ARTICLES, IN PARTICULAR, REINFORCED ARTICLES AND TYRES OF MOTOR VEHICLES Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: in proposed method article is placed in chamber, ozone-containing gas is delivered into chamber, and mechanical deforming loads are built which are applied to article. Ratio of consumption of ozone for reprocessing of articles to energy consumption for building up mechanical loads is maintained within (0.02-2) g/W.h. Ratio of consumption of ozone for reprocessing of articles (0) to mass of processed rubber (R) is maintained within 6.10^-6 and 10^-2.. Ratio of energy consumption for building up mechanical loads (M) to mass of processed rubber (R) is maintained within (0.01-250)W. h/kg. Value of O/R is maintained within 4.10^-5 and 5.10^-3 and value of M/R is maintained within (0.2-100) W.h/kg. Value of O/R is maintained within 2.10^-4 and 3.10^-3, and value of M/R is maintained within (o.6-40)W.h/kg. Mechanical loads are applied to articles with change in direction of their application from 3 s to 300 s. Device for reprocessing rubber containing article has working chamber, ozone-containing gas feeder and device for mechanical deformation of articles Device for mechanical deformation of articles is made of at least two sets of guide members one of which is installed for displacement along members of other set and is furnished with projecting working members installed for engagement with articles under processing. Sets of guide members form narrowing working clearance and are made for shifting the articles in direction of narrowing of working clearance. At least one of sets of guide members is installed for reciprocating relative to other sets. At least one of sets of article deformation device is provided with teeth for engagement with article reinforcement framework members. Sets of guide members form system orientated coaxially with tyres fed for reprocessing. At least one of sets of guide members is located at outer side of tyre. EFFECT: enhanced reprocessing of rubber-containing articles. 14 cl, 2 dwg
