Problems solved by technology
During the sewing process, it is necessary to stop frequently for placement and alignment operations, and then to sew, the production efficiency is very low, and it is easy to cause inconsistent flatness and tightness. Under this technical background, the sewing machine A special device for hemming—a hemming nozzle for a sewing machine, for example, the hemming device for a sewing machine with application number 201120141742.8
[0003] However, for fabrics that are soft and cannot be starched such as polyester, it is necessary to press the edges first at this stage, and then put the cloth strips into the mouth for processing, otherwise the cloth strips will often appear bulging and wrinkling due to the soft texture, which is extremely difficult. The ground affects the processing quality, and the raw edges of the cloth strips cannot be processed at one time, which is time-consuming and laborious, and cannot meet the needs of large-scale large-scale production

The invention provides an edge covering mouth-like device applicable to a sewing machine.The device comprises a guide cylinder fixing frame and a guide cylinder.The guide cylinder fixing frame is fixedly welded to the rear end face of the guide cylinder.One side of the guide cylinder and the guide cylinder fixing frame is provided with a protruding edge inwards, so that left and right channels are formed on the two sides inside the guide cylinder through the protruding edge, and blocking pieces are arranged at the ends of the channels.According to the edge covering mouth-like device, by means of the unique design of the blocking pieces, the technical problem that a cloth strip made from flexible fabric is likely to corrugate during overseam operation is skillfully solved, the overseam effect is uniform and flat, and the application value is high.
Description
technical field [0001] The invention relates to a sewing machine accessory, in particular to a wrapping mouthpiece suitable for a sewing machine. Background technique [0002] In the process of garment processing, for the sake of aesthetics and to show the line outline of the cap, cuffs, skirt and other parts, some narrow hemmings are often sewn on the above-mentioned parts of the garment with a sewing machine. Usually, it is manually sewn after placing and aligning the hemming cloth strips with the edges of the cap, cuffs, skirts and other parts. During the sewing process, it is necessary to stop frequently for placement and alignment operations, and then to sew, the production efficiency is very low, and it is easy to cause inconsistent flatness and tightness. Under this technical background, the sewing machine A special device for hemming—a sewing machine hemming nozzle, for example, the hemming device for sewing machines with application number 201120141742.8.
