PURPOSE:To make the ratio of a copping rate to a traverse rate alterable in an easy manner, by driving a traverse cam driving motor and a spindle driving motor both with a pulse to be added by a pulse generator via a divider. CONSTITUTION:A traverse cam driving motor 31 and a pulse motor for driving a spindle 9 both are driven by a pulse out of a pulse generator 27 via each of dividers 32 and 26, and with the dividing ratio varied, the ratio of a copping rate to a traverse rate by a driving motor 30 to be driven with a signal out of a control unit 29 is easily alterable. And, when a limit switch operates at a traverse end part, a traverse cam is temporarily stopped via a counter and after that, it is reversely rotated, while a thread guide is made to come near to an outer side of the end face of a copping mandrel 8, and the guide is reset after the elapse of the specified time. Thus such a winding round body as being small in a traverse angle and almost paralleled with a shaft of the mandrel is formable. |
