Forming die 20 can tentatively be filled to the material quantity of 1 st cloth, can practice thrift the time of a large amount of cloth once more, and the material quantity of 2 nd cloth is less, nevertheless leaves enough surplus to guarantee to make the cloth accurate after 2 nd cloth.
For example, the material usage for the 1 st cloth may be set to a 75% material demand, and then the material usage for the 2 nd cloth may be set to a 25% material demand.
Before this cloth of 2 nd, before detecting the cloth of 2 nd time according to the gravity detector, the difference of the initial material surplus in the cloth fill 11 and the material surplus in the cloth fill 11 that the gravity detector detected is 80% material demand, so controller 40 adjusts the material quantity of the cloth of 2 nd time and is 20% to change and predetermine the running speed value, so, can make the cloth more accurate.
