| 摘要 |
The invention relates to a device with a suction roller (6) which is powered by a vacuum source and has a counter-roller (10) working in conjunction with the suction roller (6) to deliver vertically stacked forms to a transport line (7). The top form in the pile is moved with its leading edge downwards between the rotating suction roller (6) and the counter-roller (10) during which process the form sticks to a row of suction holes (8) in the suction roller which conveys it downwards to the line (7). According to the invention, an O-ring (18) which is not as wide as the suction hole (8) is located exactly above each suction hole in the suction roller, which may have a metallic surface, and is partially inserted into a circular depression (19) in the surface of the suction roller in such a way that the circumference of the O-ring comes into contact with the surface of the counter-roller (10). <IMAGE>
