Embodiment Construction
[0010] exist figure 1 Among them, a method for wrapping reinforced yarns of large-length optical cables, which is characterized in that the optical fiber (1) passes through the hollow axis of the hollow fixed shaft (3), and the untwisted yarn (6) passes through the side of the bobbin (6.1) Lead out, through the yarn guide wheel (7) and yarn guide hole (5.1) on the rotary pay-off frame (5), under the continuous rotation of the rotary pay-off frame (5), the untwisted yarn (6) is continuously wound to On the outer side of the advancing optical fiber (1), the yarn bobbin (6.1) and the yarn (6) wound around its outer circumference are rotated 180° left and right to realize the left-handed or right-handed wrapping of the yarn (6) on the optical cable. conversion;
[0011] A wrapping device for reinforcing yarn of a large-length optical cable is composed of a fixed part and a rotating part. The fixed part consists of a fixed frame (2), a hollow fixed shaft (3), a yarn (6) and a bobb...
