In a box making plant, box blanks 12 are passed through a die-cutting machine 15 in joined pairs, which are separated at 18/16, the blanks 24A, 24B then being spaced apart, before entry into the box-making machine 26. This spacing is achieved by conveying each blank portion 24 from the die-cutting machine 15 by means of a conveyor belt (or set of parallel belts) 54 running at a first speed and with a first level of suction applied through holes in it to grip the blank, which is next gripped and accelerated by a second band (or set of bands) 56 driven at a higher speed and having a higher level of suction applied through it to grip the blank with a greater force and thus accelerate it with respect to the first band. <IMAGE> |
