A succession of individual dough pieces (1) on an in-feed conveyor (2) are conveyed under a pre-flattening roll (3) to be discharged between the first pair of rolls (4 and 5) of a moulding head (6). The moulding head (6) consists of two pairs of driven rolls (4, 5) and (7, 8) positioned one below the other and offset so that the line made between the centres of successive rolls (4) and (7) forms and angle of approximately 60 DEG with the horizontal. The position of roll (5) is adjustable with respect to roll (4) and is set to give a predetermined centre distance between rolls (4 and 5). The centre distance between rolls (4) and (7) and rolls (5) and (8) is arranged to create a minimum gap (approximately 1 mm) between the roll surfaces, to facilitate the omission of scrapers or deflectors. Roll (8) of the second pair of rolls is similarly adjustable to that of roll (5), both adjustment means are arranged to maintain the minimum gap between the surfaces of roll (5) and (8). Additionally, roll (8) has a means for exerting a controlled pressure onto the dough pieces. The pinned dough piece (9) is discharged onto an intermediate conveyor (10) and passes under a chain-mail coiler (11). The coiled dough piece (12) is then conveyed under a pressure board (13) to set its length. The finished dough piece (14) is then discharged into a baking tin (15). |
