PURPOSE:To place a laver sheet at a proper position and separate the laver sheet from an endless read screen with certainty, by sucking and peeling the laver sheet from the endless reed screen by a suction apparatus while turning back the endless reed screen, and adjusting the running speed of the turning back endless reed screen while sensing the turning back point of the endless reed screen with a sensor. CONSTITUTION:A laver sheet (m) is separated from an endless reed screen (M) when the endless reed screen (M) is turned back in front of a suction part (6a), and then wound by a winding roll (R). When the turning back point is at the just opposite position [a position (a)] of the suction part (6a), the endless reed screen (M) is run at the same speed as the porous belt 5 by the driving with a tension roll (R4). The laver sheet (m) is separated smoothly from the endless reed screen (M) at the just opposite position of the suction part (6a). A sensor (S) senses the turning back point of the endless reed screen (M). When the turning back point is raised, a synchronous signal generator (SG2) and a synchronous control board (SC2) are operated to reduce the rotational frequency of a motor (M2). The rotational speed of the tension roll (R4) is reduced to correct and hold the turning back point of the endless reed screen (M) to the just opposite position [the position (a)] of the suction part (6a). |
