    • 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.
    • 上部和下部织物片由压脚分开,并沿着沿着相应边缘的接缝缝合。 上部和下部织物片通过主馈线沿着一个方向馈送。 上部织物片的边缘通过设置在喉板上方的引导构件折回到后者上,导向件被加热以加热接缝。 下部织物片的边缘通过安装在喉板上的导杆折回到喉板下方。 下部织物片的折叠边缘通过辅助进给爪被提升到喉板上,并通过可与主喂入爪可移动的引导体引导到支承板上。 具有折叠边缘的上部和下部织物片在辊和支承板之间被加热压制,同时通过旋转辊沿所述方向移动。 当被引导件加热时,将蒸汽施加到接缝上。
