    摘要： A sewing machine has improved material cutting before stitching. The machine includes a sewing head and stitch area where stitching of strip material occurs. Strip material is fed by a timing belt along a predetermined path of travel into the stitch area. A lower cutter roll is positioned along the predetermined path of travel, and the strip material passes over the lower cutting roll. The lower cutter roll is driven by a transmission system connected to the sewing head motor. At least one circular configured, freely rotatable rotary knife engages the lower cutter roll and any strip material passing thereover is cut before stitching.

    摘要： 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.

    摘要翻译： 提供了一种适于与缝纫机一起使用以形成下摆的修剪装置。 修剪装置包括支撑构件，在该支撑构件上可以进给位于缝纫机的缝合针的上游的衣服的边缘。 折叠装置附接有折叠装置，该装置能够将衣服的边缘折叠在支撑构件的端部上，使得当衣物沿着支撑构件进给时边缘与针迹针对准。 固定刀片安装在支撑构件的端部的下方并且靠近支撑构件的端部，并且还与缝合针对准。 此外，可旋转的刀片定位成与固定刀片相邻，以便与固定刀片配合，使得当边缘被折叠时边缘的预定部分被修剪。 修剪装置包括旋转齿轮和用于旋转可旋转刀片的轴，以允许可旋转刀片以这种方式与固定刀片配合。

    摘要： A sewing machine may comprise a needle bar driving mechanism, a cutting needle rotation mechanism, and an embroidery frame movement mechanism configured to move an embroidery frame comprising a protruding portion. A cam member may be fixed to the needle bar and comprise a plurality of cams. A processor of the sewing machine may set a height of the needle bar to a specific position from a plurality of positions. Each of the plurality of positions may represent that each of the plurality of cams is able to contact with the protruding portion. The processor may instruct the needle bar driving mechanism to move the needle bar to the specific position and instruct the embroidery frame movement mechanism to move the embroidery frame to a position where the protruding portion is able to contact with one of the plurality of cams.
