PURPOSE:To enable a bread blank or the like to be formed into a strip having a constant width and thickness by providing in series two supply conveyers and a constant speed conveyer and controlling a drive roller of the supply conveyer according to the output of a weighing unit provided between both supply conveyers. CONSTITUTION:A bread blank 1 previously manually formed lankly is put on a supply conveyer 2 and weighed on the way of said conveyer 2 by a weighing unit 10 which weighs the weight per unit length A. And when a microcomputer detects through counting of pulses produced by a rotary transducer 9 that the blank portion An having the weighed value Xn reaches a position P corresponding to a driven roller 6 in the terminal end of the downstream supply conveyer 4, the speed of the respective supply conveyers 2, 4 having drive rollers 3, 5 and a constant speed conveyer 20 is set to meet a predetermined relationship. After the blank 1 is thereafter subjected to elongation or compression action by a holding roller 13, it is formed by the action of an elongating unit 21. |
