A sewing machine having a device for manually changing a feed dog (), including the feed dog () and a feed-dog holder (). The feed-dog holder () is disposed in an arm bed () that is associated with the sewing machine, and the feed dog () is receivable in a clearance () of the feed-dog holder (). The feed dog () that is located in the clearance () has a support face () which may be disposed parallel with the surface of a sewn-product support which may contain a needle-hole plate () or be configured as a needle-hole plate (), the sewn-product support and/or the needle-hole plate () may at least partially be formed by the surface of the arm bed (), and the support face () may be received in an opening () of the needle-hole plate (). The feed dog () is fastenable in the clearance by a fastening element () or of a setting element () such that the support face () is alignable so as to be substantially parallel with the surface of the sewn-product support or of the needle-hole plate (). The fastening element () or the setting element () is releasably held in the feed-dog holder ().

Device and method for manually changing a feed dog

A long arm quilt and lockstitch machine assembly () having a framework having two rail tracks, disposed orthogonally on top of one another, wherein the sewing machine () is disposed so as to be displaceable on the rail track lying above. The connections between the drive belt () to which the rail track () lying below and the sewing machine () are connected by way of an electronic control system via drive motors, include overload couplings which in the case of overloading by body parts or items of clothing that are caught between the movable elements separate the movable elements from the drive belts. Advantageously, the overload coupling is simultaneously a connection element and in the case of overloading separates the connection between the elements.
