ABSTRACT:
Upper and lower fabric pieces are separated by a presser foot and sewn along a seam with respective edges left therealong. The upper and lower fabric pieces are fed along in a direction by means of a main feed dog. The edge of the upper fabric piece is folded back on the latter by means of a guide member disposed above a throat plate, with the guide member heated to heat the seam. The edge of the lower fabric piece is folded back on the latter below the throat plate by means of a guide rod mounted on the throat plate. The folded edge of the lower fabric piece is lifted up to the throat plate by means of an auxiliary feed dog, and guided onto a bearing plate by means of a guide body movable with the main feed dog. The upper and lower fabric pieces with their folded edges are pressed with heat between a roller and the bearing plate while being moved in said direction by the roller being rotated. Steam is applied against the seam when it is heated by the guide member.
