<P>PROBLEM TO BE SOLVED: To improve productivity by preventing grazing on the rear side of a sheet bar and narrowing an interval between a preceding sheet bar and a succeeding sheet bar. <P>SOLUTION: As shown in Fig.2(b), when the tail end TE of the preceding sheet bar 2A and the leading edge LE of the succeeding sheet bar 2B are situated on driving roller groups 11 of a section Sn, a rotational driving command to the driving roller groups of this section is stopped, the driving roller groups are turned into an idling state. As shown in Fig.2(c), when the tail end TE of the preceding sheet bar 2A has passed through a part on the driving roller groups 11 of the last section Sn, the rotational driving command Vn is output to the driving roller groups of this section. <P>COPYRIGHT: (C)2013,JPO&INPIT |
