The present invention is described in further detail.
Refer to Fig. 1 and Fig. 2, Fig. 1 is that winding displacement provided by the present invention is automatically replenished a kind of specific embodiment of method
Flow chart；Fig. 2 is the structural representation of strand winding apparatus provided by the present invention.
In this embodiment, winding displacement is automatically replenished method and comprises the following steps：
Step S1：The surplus capacity parameter of cord when strand oscillator is moved to 1 middle part of take-up pulley is obtained, it is normal as glass pulley
Standard surplus capacity parameter A in row face0；
Specifically, real-time statistics winding displacement operates the time of a cycle, and in the interlude of next cycle, i.e. winding displacement
To take-up pulley 1 centre position when, interval takes the surplus capacity parameter value 9 times of cord, naturally it is also possible to for other number of times, during interval
