Abstract
Abstract In a method of conveying sheets along a sheet conveying path from means for non-periodically delivering the sheets to means for receiving the sheets with a predetermined periodicity comprising stopping the sheets in the path and releasing the sheets with the same periodicity as the receiving means, the improvement comprising operating the receiving means at a higher rate of sheets receivable per unit time than the average rate of sheets delivered per unit time at which the delivering means is operated.

212 words
In an apparatus for handling sheets comprising means for conveying sheets along a sheet conveying path, means for non-periodically delivering the sheets to the conveying means, means for receiving the sheets from the conveying means with a predetermined periodicity, means for stopping the sheets in the path and releasing the sheets with the same periodicity as the receiving means, and means for operating the delivering means at a first predetermined average rate of sheets delivered per unit time, for conveying the sheets to the stopping and releasing means at the first rate, and for operating the receiving means at a second predetermined rate of sheets receivable per unit time and for conveying the sheets from the stopping and releasing means at the second rate, the second rate being higher than the first rate, the improvement that the means for stopping and releasing the sheets comprises a vertically displacably mounted abutment member having an uppermost sheet releasing position, in which the lowermost extremity of the member is above the sheet conveying path, and a lowermost sheet stopping position, in which the lowermost extremity of the member extends slightly into the path, and that said lowermost extremity of the member is rounded transversely of the direction of sheet movement in the sheet conveying path.
