The compression of edge layer external diameter diminishes, and another part pulling force keeps dynamic equilibrium with wrapped bar active force.The technical scheme by regulation around
Band tension force controls the diameter of the wrapped wrapped belt of rear cable.But due to lapping equipment precision and plastics uniformity in itself
Reason, causes the tension fluctuation of twining package tape, and then causes twining package tape line footpath to fluctuate, and herein, line footpath tolerance is only capable of reaching ±
0.05mm.Further, since twining package tape tension fluctuation is big, line footpath is unstable, and this can cause the consistent of the wrapped wrapped belt of rear cable
Property and compactness are poor, the loose problem of wrapped belt structure easily occur.For the less cable of line footpath, what it was needed to use
Twining package tape size and lay of lapping are smaller, and requirement on machining accuracy is higher, it is above-mentioned it is existing around packet mode cannot meet its precision will
Ask.
