PURPOSE:To make the continuous and constant flow of a plastic blank having viscosity and elasticity by providing in series two variable speed supply conveyers and a constant speed conveyer and providing a weighing unit between both supply conveyers and a holding unit above the terminal end of the downstream side supply conveyer. CONSTITUTION:A bread blank is previously manually formed lankly and put on a supply conveyer 2 to be weighed on the way of said conveyer 2 by a weighing unit 10 which weighs the weight of the blank per unit length A. When a microcomputer detects through counting of pulses produced by a rotary transducer 9 that the blank portion An having weighing value Xn reaches a position P corresponding to a driven roller 6 in the terminal end of the dwon-stream supply conveyer 4, the speed of the respective conveyers 2, 4 and constant speed conveyer 20 is set to satisfy a predetermined relationship. Then, after the blank 1 is subjected to elongation and compression by a holding roller 14 provided corresponding to the driven roller 6, it is suspended to be transferred onto a constant speed conveyer 20. |
