1. A machine for sewing together a first panel and a second panel, said machine comprising:

  • a sewing machine for receiving along a feed direction and joining together the first and second panels;

    an arm having a longitudinal axis and being arcuately moveable about a fulcrum towards a surface of the first panel, a distal end of the arm being adapted to contact the surface of the first panel as the arm moves toward the surface of the first panel;

    means for rotating the arm about an axis normal to the surface of the first panel to rotate the first panel when the distal end of the arm is in contact with the surface of the first panel;

    a shoe biased to follow an edge of the first panel as the first panel is fed to the sewing machine;

    a detector to monitor the shoe and provide a signal indicative of a longitudinal orientation of the edge of the first panel; and

    means for adjusting the longitudinal orientation of the first panel with respect to a true feed direction in response to the longitudinal orientation signal, the adjusting means including a receiving wheel engageable with the first panel, the receiving wheel being in alignment with the sewing machine along a direction transverse to the true feed direction.
