Abstract: A device for use with a motor driven sewing machine having a reciprocating needle which in moving from an upper position to a down position penetrates a workpiece which is fed over a support past and in contact with a guide edge disposed alongside the needle in order to form a plurality of different seam lengths at diverse angles comprises a stacking device adjacent the support which includes a mechanism for feeding the workpieces into a stack. A turning device is associated with the sewing machine and is disposed alongside the support and includes a member which moves through a path to engage the workpiece and turn it about at the axis of the needle when the needle is down so as to position it in respect to the guide edge for the sewing of the next seam length. A rail switch is disposed between the stacking device and the turning device and includes a first switch position in which a path is defined between the support and the stacking device for feeding from the support to the stacking device and a second position in which a path is defined to the turning device for feeding the workpiece into association with the turning device.
