Abstract:
A method of winding a fibrous strand to build a package, the method comprising the steps of:(a) providing a moving strand; (b) rotating a collet at a rotational speed to wind the strand and build a package; (c) rotating a cam at a rotational speed to reciprocate the strand with a strand reciprocator to lay the strand at a wind angle on the package surface as the package rotates; and (d) varying the rotational speed of the cam to vary a waywind as a function of package buildup time and between upper and lower waywind operating curves to avoid waywinds outside the waywind operating curves; wherein step (d) comprises the step of varying the rotational speed of the cam so that the rotational speed of the cam is slower when starting a package buildup and then increases.
