A method for the manufacture of a material composite for a belt ply or for a carcass ply of a radially air tire

摘要

The invention relates to a method for the manufacture of a reinforcement elements containing a material composite (40, 40 '') for a reinforcement belt layer (5a, 5b, 5'' b, 5 ''c) or a casing ply (4, 4'') of a radially air tire, wherein two mixture webs (19 '', 19 "'') to be positioned between them with a strength carrier web (24) are joined together by calendering. In this case, a mixture of web (19, 19 ", 49) of a plurality of mixture strips (20, 20 '', 21, 21'', 50, 51) of the rubber mixtures and transversely or at an acute angle (α) to their longitudinal extent in the same large pieces (19a, 19" a) cut, which are spliced bluntly abut against each other in such a way that their cutting edges the longitudinal edges of the now resulting mixture web (19 '', 19 "''), which form with a second correspondingly designed mixture web (19, 19" '') as well as the strength carrier web (24) by calendering is connected in such a way that the same rubber mixtures are positioned on top of each other, whereby subsequently, the formed ultrasound (29, 29'') in the same size pieces (40a, 40 ′) is cut, which at their uncut edges to form a web (40, 40 '') are connected, in which the mixture strips (20, 20'', 21, 21 '', 50, 51) as in the original mixture web (19, 19'', 49) run.
