A method for controlling an infeed system (202) of a sheet processing machine (01), the at least one infeed system (202) comprising at least one transport means (204) including, in each case, at least one upper holder (206) and, in each case, at least one lower holder (207), the at least one transport means (204) being moved from the alignment position (PA) to the transfer position (PU) and/or back, the at least one transport means (204) in each case being arranged in at least three states, a maximally closed state corresponding to a minimal distance, and a minimally closed state corresponding to a maximal distance, and an at least one mean state corresponding to at least one mean distance between at least one upper holding surface (233) at least of the respective upper holder (206) of the at least one transport means (204) and at least one lower holding surface (234) of the lower holder (207) of the at least one transport means (204) which is assigned to the respective upper holder (206), the at least one transport means (204) being arranged in the minimally closed state at least once, and in the maximally closed state at least once, and in the at least one mean state at least once, during a machine cycle, at least one holding surface (233;
- 234) of at least one holder (206;
- 207) pivoting at least temporarily about a pivot axis (221) of the relevant holder (206;
- 207), the at least one pivotable holding surface (233;
- 234) being functionally connected to at least one cam disk (223) via at least one scanning lever (226), the at least one scanning lever (226) being coupled via at least one transmission shaft (227) to the pivot axis (221) of the relevant at least one holder (206;
- 207), characterized in that the at least one transport means (204) in the alignment position (PA), at least during a rough alignment of sheets (02) and/or during a lateral alignment of sheets (02), at least temporarily has the at least one mean state, that the distance between the at least one upper holding surface (233) and the at least one assigned lower holding surface (234), in the at least one mean state of the at least one transport means (204) in each case is at least greater than the thickness of a sheet (02) to be transported, that the position of the respective sheet (02), in the mean state, is fixed at least partially in the vertical direction (V), that the respective sheet (02), in the mean state, is movable and/or is configured to move at least in the transport direction (T) and/or transverse direction (A), and that the at least one transmission shaft (227) is eccentrically arranged in at least one adjusting shaft (228).
