Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a thread supply mechanism and a roving frame. Background Art

[0002] Roving frames are spinning machines that turn fiber strips into roving. Roving frames are divided into wing-spindle roving frames and twist-twist roving frames according to the twisting mechanism. Wing-spindle roving frames continuously apply twist to the yarn strips by rotating the spindle wings to produce twisted roving. Twist-twist roving frames clamp and twist the yarn strips with a pair of twisting leather plates, forming a false twist with alternating positive and negative twists on the yarn strips to produce non-twist roving. Wing-spindle roving frames and twist-twist roving frames can be divided into first-pass, second-pass and single-pass roving frames. The feeding forms, roving packages and number of spindles of various roving frames are different, but the machine structure and function are roughly the same.
