Abstract
An apparatus and method for closing the toe of a hosiery blank includes a hosiery toe closing machine including a sewing head having a sewing needle and a toe seam width guide. The toe seam width guide has a maximum thread guide width greater than 5 mm, preferably in the range of 6-10 mm. When the sewing needle pulls a thread around the maximum thread guide width of the toe seam width guide, the hosiery toe is closed with a wide, visible seam. The hosiery toe closing machine can include a first sewing head having a maximum thread guide width of 5 mm, for sewing a first, narrow seam, and a second sewing head having a maximum thread guide width greater than 5 mm, allowing a second seam that is wider than the first seam to be sewn over the first seam. The toe seam width guides are adjustably attached to the sewing heads for adjusting the effective thread guide width in the respective sewing heads and thereby provide corresponding adjustments to the relative widths of the first and second seams.
