A method for feeding uneven media from a high capacity feeder includes rotating the pages in a stack 180° every 100-250 pages. This is only done with non-flat pages, such as, envelopes, pages with labels thereon, etc., which create tilted stacks and limit the number of pages that can be placed in the high capacity feeder. Rotating the pages 180° distributes the uneven build-up of the pages and creates a relatively flat stack, allowing the high capacity feeder to be filled to capacity. A camera or sensor placed in the high capacity feeder will detect the orientation of the stack on the fly so the image can be rotated accordingly.

Provided is a sheet storage apparatus for storing a sheet conveyed by a sheet conveyance unit, wherein at a home position, at least a part of a sheet presence detection flag overlaps a rotational axis of a sheet presence detection flag of an adjacent sheet storage unit in a vertical direction.

An apparatus (100) for making coils, preferably for electrochemical cells intended for battery production, comprises a feed unit (2) configured to feed at least a first strip-shaped article (N1) intended to form a first coil (B1) and a second strip-shaped article (N2) intended to form a second coil (B2), a winding unit (1) comprising a plurality of winding heads (10) including at least a first winding head (11) configured to wind the first strip-shaped article (N1) and a second winding head (12) configured to wind the second strip-shaped article (N2) and at least one movement device (3) of said winding heads (10) configured to move said first winding head (11) and said second winding head (12). Said first winding head (11) and said second winding head (12) define respective winding axes (X1, X2) substantially parallel to each other. Said winding unit (1) is configured so as to define a separation plane (P), said separation plane (P) being substantially perpendicular to said winding axes (X1, X2) and being positioned so that said first strip-shaped article (N1) and said second strip-shaped article (N2) are located one on one side and the other on the opposite side of said separation plane (P) at least at said first winding head (11) and said second winding head (12).
