In the top transport device of a sewing machine, the top transport foot (15) moves in a vertical slot (27) in the arm (17), with which the top transport foot (15) is driven. This arrangement enables the top transport foot (15) to be displaced upwards into the rest position, so that accessories can be fixed to the presser bar (11).
