Abstract
A method for controlling elements for guiding sheet material and for controlling a surface for holding a sheet pile, which comprises registering, by a first sensor element, a lateral position of the sheet material and, based thereon, moving the surface for holding the sheet pile in a lateral direction, and controlling, via a sensor element for sensing a side edge of the sheet pile, independently of a first guide element, the lateral position of a further guide element, which is disposed on a side of the sheet pile, which is opposite to an aligning member for laterally aligning the sheet material and is assigned to an upper pile region; and a device for performing the method.

A method for controlling elements for guiding sheet material and for controlling a surface for holding a sheet pile, which comprises:
- registering, by a first sensor element connected to a first guide element, a lateral position of the sheet material and, based thereon, moving the surface for holding the sheet pile in a lateral direction, the first sensor element sensing a first pile edge of the sheet pile;
- and
- controlling, via a second sensor element for sensing a second pile edge of the sheet pile opposite the first pile edge, a lateral position of a second guide element independently of the first guide element, the second guide element being disposed on a side of the sheet pile opposite to the first guide element, the second guide element being assigned to an upper pile region.
A device for performing a method for controlling elements for guiding sheet material and for controlling a surface member for holding a sheet pile, comprising:
- a first guide element disposed at a first side of the sheet pile;
- a second guide element disposed at a second side of the sheet pile opposite the first side, said second guide element being assigned to an upper region of the sheet pile;
- a first sensor element connected to said first guide element for sensing a lateral position of the sheet material and, based thereon, for moving the surface for holding the sheet pile in a lateral direction;
- and
- a second sensor element connected to said second guide element for sensing a side edge of the sheet pile and, based thereon, for controlling a lateral position of said second guide element independently of said first guide element.
