Abstract

A trimming apparatus adapted to be used with a sewing machine in order to form a hem is provided. The trimming apparatus includes a support member upon which the edge of a garment can be fed which is positioned upstream from the stitching needles of the sewing machine. A folder is attached to the trimming apparatus which is capable of folding the edge of the garment over an end of the support member such that the edge is in alignment with the stitching needles as the garment is fed along the support member. A stationary blade is mounted below and adjacent the end of the support member and is also aligned with the stitching needles. In addition, a rotatable blade is positioned adjacent to the stationary blade so as to cooperate with the stationary blade in a manner in which a predetermined portion of the edge is trimmed as the edge is folded. The trimming apparatus includes rotational gears and shafts for rotating the rotatable blade to permit the rotatable blade to cooperate with the stationary blade in such a manner.
