Apparatus for stacking individual sheets

An individual-sheet stacking apparatus comprising:

• a frame fitted with two mutually opposite lateral parts,
• a base between the lateral parts,
• a support displaceably guided between the lateral parts and having a rest surface for an individual sheet stack on the side of its initially received first individual sheet,
• a guidance system for the support to displace it between a first position at the beginning of stacking at which no individual sheet as yet is present at the support and a second position at the end of a stacking procedure when the stack is full,
• a pressurizing spindle to alternatingly displace and release the support in order to insert an applied individual sheet into the gap subtended between the pressurizing spindle and the stack resting against the support and to place said sheet from the front onto the stack,
• a pressurizing shaft—of the pressurizing spindle—rotatably supported at the two lateral parts,
• two pressurizing spindle lateral elements fixed to the pressurizing shaft,
• at least two glide shafts mounted in rotatable or fixed manner to the pressurizing spindle lateral elements,
• the at least two glide shafts configured at equal radial distances from and parallel to the pressurizing shaft, said glide shafts being fitted with several glide rollers mounted in rotatable or fixed manner to said glide shafts, and
• a drive for the pressurizing spindle.
