Abstract
A folding machine comprises a blade folding unit having a first and a second folding roller, the folding roller axes thereof defining a folding roller plane, and having a folding blade which is oriented and is movable in a folding blade plane which is oriented perpendicularly to the folding roller plane and intersects the folding roller plane in an intersection line. The folding blade is arranged in a retracted position in or below a horizontal plane which comprises the intersection line.

A folding machine comprising a first blade folding unit, wherein the first blade folding unit comprises:
- a first and a second folding roller, wherein the first folding roller has a first folding roller axis and the second folding roller has a second folding roller axis which is arranged spaced apart and parallel to the first folding roller axis, so that the first and the second folding roller axes define a first folding roller plane which comprises both the first and the second folding roller axis;
- a first folding blade which is oriented and is movable in a first folding blade plane, wherein the first folding blade plane is oriented perpendicularly to the first folding roller plane and intersects the first folding roller plane in a first intersection line, wherein the first folding blade is movable between a retracted position and an extended position, wherein the first folding blade is arranged in the extended position closer to the first folding roller plane than in the retracted position;
- wherein the first folding blade is arranged in the retracted position in or below a horizontal plane which comprises the first intersection line.
A method for folding products by using a blade folding unit which comprises a first and a second folding roller and a folding blade, wherein the method comprises the steps of:
- receiving a foldable product by means of a conveying device in an inlet region of the conveying device such that the foldable product is received between a first endless conveying means and a second endless conveying means of the conveying device, wherein the first conveying means bears against a lower face of the foldable product which faces downwardly in the inlet region, and the second conveying means bears against an upper face of the foldable product which faces upwardly in the inlet region;
- conveying the foldable product by means of the conveying device in a conveying direction from the inlet region to an outlet region of the conveying device which is arranged adjacent to a folding region between the folding blade and the first and the second folding roller, wherein between the inlet region and the outlet region the orientation of the foldable product is maintained relative to a longitudinal axis of the foldable product, which is oriented parallel to the conveying direction in the inlet region;
- arranging the foldable product in the folding region, wherein the upper face of the foldable product faces the first and second folding roller and the lower face of the foldable product faces the folding blade;
- moving the folding blade in a folding blade plane in the direction of the lower face of the foldable product, and the folding blade acting on the lower face of the foldable product, so that the foldable product is forced between the first and the second folding roller;
- and
- pulling the foldable product through the first and second folding roller and thereby generating a fold line transversely to the longitudinal axis of the foldable product.
