ABSTRACT:
An automatic edge sewing system and method for sewing together the edge of a plurality of parts in which the parts to be sewn are clamped together in a sewing machine having a reciprocating needle; the parts are mounted for rotation about a first rotational axis through the pans and for linear translation along a linear axis between the first rotational axis and the axis of the needle. The pans are steered about a second rotational axis parallel to the needle axis for adjusting the angular position of the linear axis about the needle axis. The parts are fed through the needle axis and the position of the edge of the parts proximate the needle axis is sensed; the steering and the feeding of the parts through the needle axis is controlled in response to the sensing of the edge position while the pans passively float about the first rotational axis and along the linear axis to enable the parts to be sewn accurately, automatically proximate the edges.
