<p>The invention addresses a feeder of blanks (1) made of cardboard or the like, which are fed in stacks (P) composed of a predetermined number of identical and congruently superimposed blanks (1), which feeder is composed of a feed magazine (2) and a feed hopper (3), which forms an extension of the magazine (2), the magazine (2) and the hopper (3) being oriented with their axes parallel to the direction of feed of the blanks (1) that are oriented downward with respect to the horizontal plane, each of which blanks (1) has at least two oppositely projecting portions (101), which are designed to lie on lateral slide guides provided within the magazine (2). According to the invention, said lateral guides consist of at least two parallel toothed belts (4, 4'), for transporting the blanks (1), which belts support the lower edges of the projecting portions (101) thereof, there being provided means (6) for synchronously driving the two belts (4, 4') toward the hopper (3). The invention also relates to a feeder which comprises means for breaking up the stacks of blanks (1). Such break-up is obtained by providing that the hopper (3) has a steeper slope than the magazine (2), with respect to the horizontal plane, and that the blanks (1) are guided along an arched path extending between the exit (102) of the magazine (2) and the entry (103) of the hopper (3) which causes them to open out in a fan shape.</p> |
