<p>Blowing member (20,20a,20b,30,30a,40), in particular for the cooling of a glass in a tempering cycle, characterised in that it comprises: - two or more parts (21,22,23; 21a,22a,23a; 21b,22b,23b; 31,33; 41,42,43,44,45) rotatably connected with each other, each part belonging to: - a first type (21,23; 31,33; 41,43,45; 21a,22a,23a; 22b; 31a), wherein the part is constituted by two linear portions (C1D) placed side-by-side and integral to each other, of different length, so as to constitute a body (21 ',23'; 31 ',33') and one or two wings (21 ",23"; 31 ",33"); or - a second type (22; 21b,23b; 33a; 42,44), wherein the part is constituted by an only linear portion constituting an only wing; each linear portion (C1D) presenting at least a linear series of fluid-blowing elements (E), the fluid being in particular gas or air; and in that: - said two or more parts are connected with each other, by rotatable connection means (50), in correspondence of the internal region of the relevant wings, in such a way that: - when all the parts are oriented along an only straight line, the blowing member is constituted by parallel linear series of fluid-blowing elements (E). The invention further concerns a cooling apparatus and a tempering plant utilising such a blowing member.</p> |
