Abstract

According to the invention, a number of sheet materials P1 are successively delivered to and clamped between a plurality of clamp rollers 5. A servo motor 6 is operatively connected to the clamp rollers 5 to rotate the latter. A detector PH1 is disposed upstream of the clamp rollers 5 and detects the position of the sheet material P1. Further, a control device 9 is connected to the servo motor 6 and the detector PH1 to control the servo motor 6 to momentarily decrease its number of revolutions (R.P.M.) in response to the detection signal from the detector PH1 immediately before the sheet material P1 is completely discharged from the clamp rollers 5. The rotative speed of the clamp rollers 5 is therefore momentarily lowered so that the sheet material P1 is discharged at low speed. Accordingly, the sheet material P1 conveniently falls down onto a table 8 so that sheet materials P1 are regularly stacked on the table 8. No backling takes place in the leading end of the sheet material P1.
