Abstract

PURPOSE: To control an amarture current of a d.c. motor corresponding to a rotative speed of a winding reel, to reduce the change in a tensile force of a wound material which occurs due to the increase in a rotation radius of the winding reel and to easily eliminate the unevenness in the quality of the wound material.
CONSTITUTION: A winding reel 4 winds a wound material 3 in a D width through the work of a gear box coupled by means of a d.c. motor 1. A pulse generating circuit 10 generates a pulse at every time when the winding reel 4 rotates. A counter 11 counts the pulses, and an output of the counter 11 is applied to the d.c. motor 1 via a D/A converter 12, AND circuit 13 and a transistor 15. An armature current is thus controlled.
