Abstract
An attachment for cutting the edge of a length of material travelling towards a sewing location is mounted on the working or operating surface of a sewing machine. A drive fork is acted upon by a needle bar and drives a movable cutter blade via a drive or control cam carrier. The movable cutter blade is arranged at a blade holder which is pivotable about a pivot axis which is laterally spaced from a cutting plane defined by the movable cutter blade and a fixed cutter blade. A large throughpassage or space for strips separated from the length of material by the cutter blades is formed between the cutting plane and the blade holder.
