ABSTRACT:
A method of winding a narrow strip having a width W on a bobbin at an angle.theta. to the rotational axis of the bobbin and at a pitch P, while the bobbin and the strip are being relatively traversed over an axial stroke S of the bobbin, characterized in that setting the integral part as A and the decimal part as B of the calculated numerical value of rotational number n the bobbin per reciprocating traverse of the bobbin or strip which is expressed according to the formula n=2 S/P, the winding is carried on, in the case when P<2W/sin .theta., while controlling at least any one of P, S, and (P-W/sin.theta.) so that (1-W/P sin.theta.)<B<W/P sin .theta.. Thus, A narrow strip can be soundly wound on a bobbins while avoiding any collapse or other disorder in winding or any damage of the strip by adjusting the value of B that depends delicately upon the values of P and S.
