DRIVE-CLAMPING MACHINE

PURPOSE:To obtain a drive-clamping machine which can execute a temporary drive- clamping and a regular drive-clamping by a run of once, and can execute an extremely efficient driving and clamping work by providing the first receiving roll and the first driving and clamping roll before and behind the advance direction, and providing the second receiving roll and the second driving and clamping roll of the last stage, on its middle. CONSTITUTION:This driving and clamping machine is set to a lower drive part Pa and an upper drive part Pb, and thereafter, each roll is turned by driving a motor M. That is to say, by the first receiving roll 7, the first drive-clamping roll 8, the second receiving roll 10 and the second driving and clamping roll 11, a driving and clamping work extending from the first stage driving and clamping to the second stage (final) is executed. In this case, no driving and clamping work is executed by the roll 7 and the roll 8 being in the rear position of the advance direction. Subsequently, even in case when the longitudinal direction of a drive-clamping use building plate P is curved, the same driving and clamping machine is set to its curved state. In this case, the roll 10 and the roll 11 are made to ascend suitably against a spring 12. Also, at the time of a curved part, it is changed to a position of a motor M, a driving gear 16 is set, and the subsequent driving and clamping work is executed in the same way as a straight line.
