of this invention fig5 shows a conventional laminating means a so called parallel piler consisting of three conveyors 13 14 15 which cooperate to continuously laminate the dough the first conveyor 13 continuously feeds the dough sheet onto the second conveyor 14 the second conveyor 14 positioned beneath the first conveyor 13 reciprocates to feed the dough sheet in the reverse direction and when it retracts it causes the dough sheet to fall onto the third conveyor 15 positioned beneath the second conveyor 14 and adapted to reciprocate such that it moves in directions reverse to the movement of the second conveyor 14 these conveyors move the dough sheet slidingly back and forth place the dough sheet on a conveyor 16 and thereby complete the lamination of the dough sheet the laminated dough is accumulated on a continuously moving conveyor 16 placed at right angles to the conveyors 13 14 and 15 and thus the traveling direction of the laminated dough sheet is changed by 90 degrees fig6 shows a laminating means used in another embodiment of this invention it consists of a swinging mechanism 17 and a conveyor 18 the swinging mechanism 17 consists of a pair of swinging plates 19 and a swinging shaft 20 on which the swinging plates are pivotally supported the dough sheet is fed.
