摘要： An automatic industrial sewing machine which increases productivity and improves quality in the sewing of linings to facing material in the manufacture of jackets. The machine automatically inserts a plurality of different rates of fullnesses at predetermined locations in the seam between the lining and the facing, for a preset number of stitches for each fullness. It also provides positive feeding for piping sewn into the seam which eliminates stretching or bunching of the piping. Finally, the material is held in position after release of the drag clamp by the use of a jet stream of air impinging on the material. The operation of the machine is automatic in that the operator need only place the facing and lining into the drag clamp and into the air guide and depress a switch. The machine then automatically sews the seam with or without piping, inserting the fullnesses desired in the seam, automatically cutting the piping prior to, and at the end of, the sewing of the seam, and automatically transporting the material to a stacker.

摘要： A sewing machine is provided having an automatic bobbin loader. The automatic bobbin loader includes a hook assembly mounted beneath the sewing plane having a bobbin receiver. The hook assembly is driven by a drive shaft, and is moveable from a first, operating position, to a second, loading position. A bobbin loader is mounted adjacent to the hook assembly in the second position. The bobbin loader includes a suction tube that removes any remaining bobbin core. The bobbin loader then loads a replacement bobbin from the bobbin loading assembly into the bobbin receiver, prior to the hook assembly being returned to the operating position. Additionally, in order to sew through thick material, the needle is carried by a needle carriage which moves in time with the material being sewn to maintain the needle generally vertical throughout the time it is in the material being sewn.
摘要翻译：提供一种具有自动线轴装载机的缝纫机。自动线轴装载机包括安装在具有线轴接收器的缝纫平面下方的钩组件。钩组件由驱动轴驱动，并且可从第一操作位置移动到第二加载位置。在第二位置中，与钩组件相邻地安装绕线筒装载机。筒管装载机包括一个抽吸管，该吸管除去任何剩余的筒芯。然后，在钩组件返回到操作位置之前，筒管装载机将替代筒管从筒管装载组件装入筒管接收器中。此外，为了缝合厚的材料，针由针架承载，针架随着正在缝合的材料及时移动，以在被缝合的材料中保持针头大致垂直。
