Abstract

The present invention provides a fabric transferring device of a sewing machine. The device comprises a fabric feeding tooth for feeding of fabrics and a pressure leg. A pair of left and right fabricfeeding belts are arranged at the external portions of left and right sides of the pressure leg in a direction approximately orthorhombic to a sewing traveling direction and is acted at the upper surface of the fabric, the fabrics are forcedly transferred in a length range being in contact with a needle plate in a sewing traveling direction at the surface of the pressure leg. The device further comprises a transmission belt drive mechanism configured to allow the fabric feeding belts to perform synchronization connection with the fabric feeding tooth to cause intermittent drive and a belt up-and-down movement drive mechanism configured to perform drive and connection and up-and-down movement of the fabric feeding belts and the pressure leg. The cost is low compared to the addition of partsof the sewing machine, and in a condition that part and all of fabrics pasting rubber and the like are taken as sewing objects, if even the fabric sewing portions are subjected to transferring resistance caused by friction, and transferring is reliably and smoothly performed to complete a good sewing product.

Description

technical field [0001] The present invention relates to a material transfer device of a sewing machine such as a double-needle horizontal cylinder double-thread overlock sewing machine, which is suitable for sewing the front and rear body materials such as T-shirts and sweatshirts to form a loop. In the case where the end of the circle material is sewn with end stitches for preventing thread unraveling, etc. Background technique [0002] For example, a double-needle type double-thread lockstitch sewing machine used for sewing end stitches of a round material has a needle plate that guides the sewn portion of the round material (the end edge is turned back toward the back side of the material) And the superimposed overlapped fabric part) is fed along the prescribed sewing travel direction; a plurality of (two) machine needles, which are arranged side by side in the direction perpendicular to the sewing travel direction, can be formed on the above-mentioned needle plate The w...
