Claims21
An apparatus for separating flat products from a pile of flat products, the apparatus comprising:
- a plurality of needles arranged in at least one needle group;
- a respective needle block associated with each of the at least one needle group, the associated needles being disposed thereon, the respective needle block being movable between a closing position and an opening position, the associated needles supporting a bottom of a pile of flat products when the respective needle block is in the closing position and in the opening position;
- and
- a respective group adjustment device associated with each of the at least one needle group for adjusting a group position of the respective needle group between the closing position and the opening position.
A method for separating flat products from a pile of flat products, the method comprising:
- providing a plurality of needles arranged in at least one associated needle group disposed on a respective needle block movable from a closing position to an opening position, the needles supporting a bottom of a pile of flat products in the closing position and the opening position;
- moving each of the respective needle block between the closing position and the second position so as to adjust a group position of each of the at least one needle group using a respective group adjustment device associated with the respective needle group.
