Device (1) for the longitudinal alignment of plate elements (2) within an infeed station of a machine working them. The aforementioned device is secured by two lateral brackets (9, 10) between which is settled a conveyor track for the said plate elements, comprising two plates (5, 6) folded downwise according to a line (7) non-perpendicular in the meaning of the shifting (3) of the said plate elements (2). The latter are moved downstream by means of at least two conveyor belts running around at least two pulleys (15, 16) secured between unmovable bearings (11-14) at the input of the said device. The device (1) has on its leading edge a protection plate (39) over which are flaps (30-32) movable and interdependent of a transverse shaft (24) connecting the leading edges of the two lateral brackets (9, 10). This shaft is moved by an alternate rotation between 0 and 45 degrees, synchronized with the production speed of the machine in order to allow the successive alignment of the said plate elements (2). It has as a characteristic to be linked and made of several segments (26-28) each one of them bearing one of the said flaps (30-32). |
