Abstract: The apparatus according to the invention consists of a hollow rotating cylinder 10 having openings 14 disposed at regular intervals the length of its peripheral surface. Said cylinder is engaged in stepping rotation by hollow shaft 34. A cylindrical block is situated inside cylinder 10, said cylindrical block being composed of two stationary elements 18 and 19 connected to a stationary tubular piece 26 containing a pivotable shaft 23. The pivotable shaft has a toothed pinion 22 attached to its anterior end, which pinion cooperates with grooved slides 20 and 21, which serve both as the means for ejecting products and as a movable base for the folding cavity once the products has been positioned therein.
