    • In a computer-controlled sewing machine for performing a joining operation, e.g. on shoe uppers, a workpiece holder comprises three clamp members one of which is fixed, defining a reference plane, and the others are movable. Two members are provided with workpiece component locating means for locating components in relation to one another and to the sewing instrumentalities of the machine. In use, a first component is located on the first member and is then clamped between the second and third members and, with the first member retracted, a second component is located by the second, fixed, member and then clamped by the first and third members. This facilitates work-handling and improved output of the machine. For selecting a desired sewing pattern, sensing means is provided which detects the particular workpiece components clamped and signals the computer control means of the machine accordingly.
