Abstract

This is a device lying in the production sector of machinery for the construction and/or refurbishing of tyres; it serves to accommodate the carcass of the tyre and enable a "tubeless" inflation. It is to be used for the most part on tread rasping or tread rolling or camelback machines and also on packaging machines. The invention for the most part concerns the outermost (righthand) flange containing the tyre bead, which is of the expansion or "semirigid" type, so that it allows the carcasses to be introduced from the outer side of the flange itself and is opposite a rigid flange of normal (left-hand) type, so as to produce a rigid and inflatable support for the carcasses themselves. Another not inconsiderable advantage is that this device simultaneously combines the advantages of the adjustable- width "plate type" support system with the advantages of the "expandable chuck" type system, eliminating the drawbacks of both systems, that is, defects and lack of precision in centring for the expansion chuck and the need for framework structures to contain the static thrusts due to the inflation of the carcasses. <IMAGE>
