Abstract

A knife folder for folding a sheet material comprises a sheet-material feeder for feeding the sheet material in a first direction, a folder for folding said sheet material, and a sheet-material conveyer used for conveying the sheet material and comprising at least one pair of rotating conveying components whose axes of rotation are arranged in a second direction substantially at right angles to the first direction. The folder pushes the folded sheet material between the conveying components of the at least one pair of conveying components when it is at its folding position. The sheet material is advanced up to a stop. The folder comprises a knife extending in a third direction substantially at right angles to said first and said second direction. The sheet material can be conveyed in the third direction by actuating the conveying components.
