Abstract

A spinning take-up device 1 includes a guide body 16 having a fulcrum guide 31, and a controller 60. The controller 60 switches a rotation speed of godet rollers 3 and 4 between a first yarn winding speed and a first yarn threading speed. The controller 60 switches a rotation speed of a bobbin holder 13 between a second yarn winding speed and a second yarn threading speed. The fulcrum guide 31 has a cylindrical shape and is rotatable around the central axis. In the spinning take-up device 1, a maximum rotation speed of the fulcrum guide 31 in an acceleration period is larger than a maximum rotation speed of the fulcrum guide 31 in a constant speed period. The guide body 16 is provided with a rotational resistance applying means 37 that applies rotational resistance to the fulcrum guide 31 so that the rotation speed of the fulcrum guide 31 in the acceleration period is less than 14400 rpm.
