    摘要： In a method and apparatus for applying a protective strip by sewing to an end of a slide fastener, a continuous protective strip is fed downwardly toward a tape supply position on the base of a sewing machine with its one surface facing opposite to a direction of feed of a slide fastener until a leading end portion of the protective tape overlays the base by a predetermined length, then the leading end portion is bent in a direction opposite to the fastener feed direction by a stream of pressurized air issued from an air nozzle, thereafter, a slide fastener is advanced along the base until its leading end reaches to a sewing position located downstream of the tape supply position, thereby causing the leading end portion of the protective tape to bend into a U-shape extending from the back to the face of the slide fastener around the leading end thereof, then the U-shaped leading end portion is cut from the continuous protective tape, thereby forming a U-shaped protective strip which in turn is sewn to the leading end of the slide fastener.

    摘要： A work table is divided at least into a spreading station and a cutting station, has a flat, substantially smooth upper surface and a plurality of apertures extending through the top of the table for passage of air currents therethrough. A reversible pump generates and delivers the air current to said apertures through a plurality of separate conduits connected to each of the apertures. A spreading device, which spreads, cuts, and stacks individual layers of fabric is provided with a plurality of air jets for selectively applying a thin film of air over the top of the fabric layers as they are spread. While the stack is being formed, the pump draws air through the fabric stack and down through the work table surface to hold the stack in place. When the stack is completed the pump is reversed so that a positive air pressure creates a cushion of air between the stack of fabric and the work table to move the stacked material to the cutting station. When the stack has reached the cutting station, the pump is again reversed, drawing air down through the fabric stack to hold the stack in place during the work process.

    摘要翻译： 工作台至少分成扩展站和切割站，具有平坦的，基本平滑的上表面和延伸穿过工作台顶部的多个孔，用于使气流通过。 可逆泵产生并通过连接到每个孔的多个分开的导管将气流传送到所述孔。 布置，切割和堆叠各层织物的扩散装置设置有多个空气射流，用于在织物层的扩展时在织物层的顶部上选择性地施加薄膜的空气。 当堆叠正在形成时，泵将空气通过织物堆叠并向下通过工作台表面以将堆叠保持在适当的位置。 当堆叠完成时，泵被反转，使得正空气压力在织物堆和工作台之间产生空气缓冲垫以将堆叠的材料移动到切割站。 当堆叠已经到达切割站时，泵再次反转，在工作过程中将空气向下抽吸通过织物堆叠以将堆叠保持在适当位置。

    摘要： Sheet material is taken from a supply, moved along its length to a cutting station, the sheet material is cut into segments, and the cut segments are moved parallel to their cut edges, the cut edges are hemmed, and the segments are folded. At the cutting station the leading portion of the sheet material is gripped and pulled from the entrance to the cutting station to the other side thereof, a slack bar is moved downwardly into the segment of sheet material in the cutting station to form slack in the segment, and the segment in the cutting station is clamped against parallel conveyor tapes. A cutting disc is drawn across the sheet material at the entrance to the cutting station, and the parallel conveyor tapes move the sheet parallel to its cut edges to a hemming station where the edges are folded and hemmed. The hems of the side edges are expanded after being mechanically formed and prior to being sewn. The leading and trailing edges of the folded portions of the hems are aligned with the leading and trailing edges of the unfolded portion of the hem as the segment approaches the sewing machine.

    摘要： Sheet material, for instance fabric, is edge-guided automatically in conjunction with work-feeding mechanism of a machine. The edge guidance means includes an edge gage in combination with an airflow device arranged to direct a stream of air substantially parallel with the material in a channel slidably confining it to urge the edge of the material progressively into contact with the edge gap. By way of illustration only, the invention is shown herein as used in a margin-coating machine, and in a hemming device.
