PURPOSE: To guarantee the linear conveying of a plate form body, and to remove a resin component attached to rolls, by changing the roll diameters of the upper side and the lower side feed rolls so as to generate the rotation-speed difference, as well as inclining the shaft-centers of the feed rolls which consist of a pair of the upper and the lower rolls, at a desired angle each other.

CONSTITUTION: While the shaft center of either one side feed roll 1 or 2 is inclined to the other side shaft center at a desired angle, either one side feed roll diameter is made different to the other side feed roll diameter, and a gear 17 installed to the shaft end of the lower feed roll 2, and a gear 17 installed to the shaft end of the upper feed roll 1 are engaged so as to rotate the feed rolls in the reverse directions. As a result, the roll load of the feed roll 1 is provided as a linear pressure in an even distribution or close to an even distribution, so as to guarantee a linear conveying, and at the same time, by the difference of the rotation speed of the feed rolls 1 and 2, a resin component leaked from the plate form body and attached to the rolls is drawn out and removed from the feed rolls 1 and 2.
