PURPOSE: To make sure of an attractive separation by detecting that whether there is a wire bet at an attractive separing means or not as well as there are plural sheets or not, respectively by a detecting means, and varying the attractive separating force by the signal through attractive separation adjusting means, then separating those of separating plural lower wire nets with separating means. ;CONSTITUTION: When a lath net pile 3 stacked on a lath net loading plate 1 equipped with a lifting means 2, two electromagnet lifting cylinders 4 and 4 are to go up and down, and they are attractively separated from each other by dint of plural electromagnets 5 and 5. At this time, such a fact that whether there is a lath net attracted or not as well as there is one piece or plural pieces is detected by two sensors 6 and 6, and in the case where the magnets fail to attract even one piece of these lath nets, voltage in each electromagnet 5 is raised improving its magnetic attraction yet more, but when plural pieces are attracted, the voltage is lowered, making its attraction go down. In addition, when plural piece of them are attracted likewise, a separating electromagnet 9 is uplifted to a position conformed to the electromagnet 5 by an air cylinder, and the lath net is attracted by this separating electromagnet 9 from the underside of the lath net. In this state intact, the air cylinder is retracted, whereby an excessive lath net is separated from the topper lath net.;COPYRIGHT: (C)1996,JPO
