LONG ARM QUILT AND LOCKSTITCH MACHINE ASSEMBLY

A long arm quilt and lockstitch machine assembly (1) having a framework having two rail tracks, disposed orthogonally on top of one another, wherein the sewing machine (19) is disposed so as to be displaceable on the rail track lying above. The connections between the drive belt (33, 43) to which the rail track (9) lying below and the sewing machine (19) 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.
