ABSTRACT:
As a web of material is guided along an L-shaped path toward a sewing station, the web is progressively folded in the first leg of the L-shaped path, and the web is refolded into a binding fold as it turns from the first leg to the second leg of the L-shaped path. The folder through which the web of material passes progressively shapes the web into the desired fold, and the folder is open along its upper edge so that if the material is too wide or irregularly shaped, the upper edge of the material can protrude out of the folder as the material is being folded along the first leg of the L-shaped path, and when the material is being refolded, the protruding edge of the web is folded into the binding fold.
