<p>The invention relates to a means for removing protruding parts, such as protuberances, burrs and the like, from tyres (4) and similar articles (trimming means) by embrittling and breaking these parts, it being possible to process tyres of different sizes one after the other as desired in an unordered manner, the means having a mounting frame or a housing, which contains a cold-embrittling device (3), i.e. a cooling device, and a breaking tool as well as devices which accomplish the individual separation, clamping, transporting and processing movement of the tyres in the housing. Problems in neatly removing the protruding parts over the entire tyre contour are solved by the installation according to the invention in that a ribbed non-rigid band (20), comprising connected individual elements or a wire mesh or the like, is suspended as the breaking tool in the mounting frame or housing in such a way, for example in a liquid nitrogen bath representing the embrittling device, that the cold-embrittled tyres are able to be brought with the treads up to this band (20), the band leaning against the respective tyre profile and consequently, due to the processing movement of the tyre, preferably a rotation, the protruding parts being broken off.</p> |
