ABSTRACT:
A cutting device for a sewing machine is provided with a cutting instrument associated to a cutting zone. The cutting instrument is formed with a blade movable towards the cutting zone. Furthermore, a protective guard is provided with a blade cover surrounding the blade, movable from an inoperative position spaced apart from the cutting zone to a position in front of the cutting zone. The blade and the blade cover are drivable in such a manner that the blade is only movable towards the cutting zone after the blade cover has been moved in front of the cutting zone. In order to reliably position the blade cover in front of the cutting zone prior to the movement of the blade to the cutting zone for performing the cutting operation, a mechanical locking mechanism is provided for the blade, which is only released when the blade cover is positioned in front of the cutting zone. The blade cover is non-positively connected to its drive in order to prevent injuries by the blade cover.
