Abstract:
A sheet holder for holding a sheet of paper and exposing an edge of the sheet, has a press for holding the paper sheet and exposing the edge, and a lever for operating the press. The lever is movable between a released position for placing of the edge of the paper sheet in the press and a holding position for operating the press. There is also an abutment for abutment by the edge of the paper sheet to position the edge relative to the press while the lever is in the released position. The abutment is associated with the lever for moving away from the edge of the paper sheet when the lever moves towards the holding position, thereby exposing the edge of the paper sheet.
Abstract:
A trimmer for trimming brochures has lower blade holders and upper blade holders for top cutting blades and bottom cutting blades lying opposite them. The trimmer further has a guide rail configuration and tensioners by which the lower blade holders can be locked on the guide rail configuration. Accordingly, the tensioners can be actuated from one and the same side of the trimmer. This has an advantageous effect on the time required for changing over the trimmer from one brochure format to another.
