Abstract
Sewing apparatus for joining a first panel and a second panel and having an arm that is rotated about an axis normal to the surface of the first panel to rotate 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. An edge flattener including a generally cylindrical component is provided.
