ABSTRACT:
An arrangement for the stackwise depositing of individual sheets of equal lengths in a repository or file by means of a conveying arrangement which includes one or more vacuum conveyor rolls or webs, adapted to transport successive sheets which are introduced in a time sequence from an input to the repository at a definite conveying speed, and including a braking installation located preceding or ahead of the repository, which deflects the end of each sheet downwardly out of the plane of conveyance and reduces the conveying speed to a speed which provides for an undisturbed deposition, and wherein the aspirating effect of a vacuum conveying roll which is located in proximity to the braking installation is interrupted during actuation of the braking installation. In an arrangement pursuant to the above-mentioned type, the vacuum conveying roll, which is located in proximity to the brake arrangement, is perforated for only a portion of its periphery, and so rotates in rhythm with the insertion of the sheets, that the perforated peripheral portion of the vacuum roll runs synchronously with the leading or initial portion of each sheet, and the unperforated peripheral portion of the vacuum roll faces towards the end or trailing portion of each sheet, when the sheet end is located within the effective range of the brake arrangement operating in rhythm with the sheet insertion.
