Abstract (en)
[origin: EP0394707A1] The device for sequentially feeding sheets, placed in the feed station of a processing machine, comprises at least one linear feed element (4) passing over an idler pulley (14) and attached at its two ends (16 and 17) onto a drive pulley (18) driven in a rotary to-and-fro movement and at least one low-pressure chamber (2) formed by caissons (3) which can be individually isolated with the aid of a shutter device (73) and connected together to a vacuum source. Discontinuous-circumference rollers (12) are disposed beneath the upper side of the linear feed element (4) and their angular regulation is produced synchronously with the linear movement of the linear feed elements (4). <??>The device finds application in the field of machines for processing corrugated cardboard. <IMAGE>
