Abstract
The present specification describes and claims an apparatus for the folding of paper webs or similar materials for the formation of a stack made up of folded layers. The apparatus has a laying arm adapted to perform a reciprocating motion while laying out the layers to form the stack, and at least one folding screw which, in use, is located in the region of a corner of the stack. The folding screw is arranged with its axis extending substantially vertically to the plane of the layers and with its leading edge entering from the side of the stack between layers to be folded. The at least one folding screw is adapted to rotate twice for each reciprocating cycle of the laying arm and a pressing-down element is arranged to, in use, act upon the top layer succeeding the last fold, so as to be effective on the top layer in the region where the leading edge of the folding screw enters in between the layers.
