Claim 10:
11. A method for cutting a sheet pile by means of a pile cutting device, the sheet pile initially resting on a first pile bearing surface of a first bearing device, the method comprising:
in a first forward-feed operation, moving the sheet pile in or counter to a first horizontal direction in relation to a first cutting unit, by movement of at least two upper pressing elements acting vertically from above on the sheet pile,
in a first lowering operation, lowering a rotary plunger that is pivotable about a vertical pivot axis such that a lower contact surface of the rotary plunger makes contact with the sheet pile,
in a first release operation, moving the at least two upper pressing elements upwardly and off the sheet pile,
in a first pivoting operation, pivoting the rotary plunger about the vertical pivot axis, to cause the sheet pile to pivot about the vertical pivot axis,
in a second lowering operation, moving the at least two upper pressing elements downwardly and into contact with the sheet pile following the pivoting,
in a second release operation, moving the rotary plunger upwardly and off the sheet pile while the at least two upper pressing elements contact the sheet pile,
in a second forward-feed operation, moving the sheet pile in or counter to the first horizontal direction by moving the at least two upper pressing elements, and
following the second forward-feed operation, in a first cutting operation, cutting a partial pile off the sheet pile by means of the first cutting unit.
