1. A shear for cutting and simultaneously conveying pairs of rolling wires or bars, comprising:
a) a mobile diverter comprising two channels, each channel being configured for one of the wires or bars to slide therein, the mobile diverter being moveable to provide a movement of the mobile diverter;
b) two pairs of counter-rotating knives, each pair of counter-rotating knives acting on a respective one of the wires or bars to produce respective segments of wire or bar;
c) a conveying device for conveying the segments of wire or bar, the conveying device comprising first and second pairs of output channels for conveying the segments of wire or bar, the first pair of output channels comprising a first lateral channel and a first central channel, the second pair of output channels comprising a second lateral channel and a second central channel; and
d) first and second mobile elements, wherein the first mobile element is positioned immediately before the first central channel and the second mobile element is positioned immediately before the second central channel, the first and second mobile elements being synchronized to move vertically and simultaneously, each of the first and second mobile elements moving between an upper position where the respective central channel is totally closed and a lower position where the respective central channel is totally open, the first and second mobile elements being synchronized with the movement of the mobile diverter so as to facilitate insertion of each of the segments of wire or bar in one of the first or second central channels or one of the first or second lateral channels of the first and second pairs of output channels;
wherein the first and second mobile elements are arranged mirror-wise with each other and each of said first and second mobile elements include:
a lateral containment wall;
a sliding surface arranged transversally to said lateral containment wall;
a conveying surface inclined with respect to said lateral containment wall; and
a wedge-shaped element, the wedge-shaped element having exterior surfaces defined by said sliding surface and said conveying surface, a base of the wedge-shaped element resting on a portion of the lateral containment wall;
wherein the first lateral channel has a first inner side and a first outer side, and where the second lateral channel has a second inner side and a second outer side;
wherein the first lateral channel is delimited on the first outer side by a first outer lateral wall and on the first inner side initially by the lateral containment wall of the first mobile element and then by a first intermediate partition, and wherein the second lateral channel is delimited on the second outer side by a second outer lateral wall and on the second inner side by the lateral containment wall of the second mobile element and then by a second intermediate partition.
