ПРОЕКТУВАННЯ МЕХАНІЗМІВ ШВЕЙНИХ МАШИН ДЛЯ РЕАЛІЗАЦІЇ ТРИНИТКОВОГО ЛАНЦЮГОВОГО ЗИГЗАГОПОДІБНОГО СТІБКА

Purposel. Development of a method of designing the mechanisms of sewing machines for the realization of three-thread chain stitch zigzag. Methodology. Use common method of design chain stitch sewing machine as a basis, which put the theory of similarity determining the optimal value of stroke working bodies as the basis for the design of appropriate mechanisms. Findings. This paper proposes a method for determining the optimum parameters of units of sewing machines mechanisms that enable the implementation of a new type of three-thread chain stitch zigzag. Originality. The basic procedures and algorithms for designing mechanisms of sewing machines to perform trehnitochny zigzag chain stitch of a new type. Practical value. The proposed method can be applied in designing arrangements sewing machines to perform zigzag stitch. [ABSTRACT FROM AUTHOR]
