Abstract
The method consists, while the ream is applied against a curved surface, in exerting pressure forces against the outer sheet of said ream, along a line of application parallel to the generatrices of the curved surface, moving this line over the entire length of the ream, and beyond each of the edges of the sheets, thereby releasing the sheets. The intensity of the pressure forces enables the sheets to be kept against the curved surface and the speed of movement of the line of application is adjusted in order for the released sheets successively to move away from the remaining curved sheets, thereby reestablishing a plane ream, this reformed ream being jogged.

A method for separating the sheets of paper stacked vertically in reams of sheets, by applying the ream against a curved surface in order to separate the sheets of this ream, in which method, while the ream is being applied against the said curved surface, pressure forces are exerted against the uppermost sheet of said ream along at least one line of application parallel to the generatrices of the curved surface, said line of application is moved perpendicularly to the generatrices of the curved surface over the entire length of the ream and then beyond each of the edges of the sheets, thereby releasing the sheets, the intensity of said pressure forces remaining sufficient, during sheet movement, to keep the sheets against the curved surface, the speed of said movement being adjusted so that the released sheets successively move away from the remaining curved sheets, thereby re-establishing a plane ream, and this formed ream is jogged.
