Bases of parametric synthesis of the passive system of thread supply of the automatic half-hose machine

Purpose. Development of the basic provisions of the parametric synthesis of the passive system of thread supply of the automatic half-hose machine by the condition of a given thread tension in the knitting zone on the basis of calculations of thread tension along the contour of the refueling line. Methodology. Is used the dependence between the input and output tension of a thread on the basis of Euler's formula, which take into account also the additional tension of a thread at bending, the design basics for the tract of movement thread at minimizing the total wrap angle by elements of the thread supply system and also the method of additional argument. Findings. Presented by calculations for the parametric synthesis of the passive system of thread supply for the definition of rational coordinates of the positions of its a basic elements, which contribute the provide of a given thread tension at the entrance to the knitting system. Originality. Consists in subsequent development of theory and methodology of deciding of the applied design tasks for providing of sufficient thread tension at the entrance to the knitting system when used the total wrap angle by the elements of the thread supply passive system Practical value. Are presented the practical recommendations that contribute to the development of organizational and technical measures for improve the passive system of thread supply for the automatic half-hose machine. The proposed approach also allows analyzing and correcting the adopted design decisions at the design stage
