Abstract (en)

Conventionally, in a yarn winding machine having a yarn feed roller wherein a contact roller is capable of being displaced relative to a roller supporting member, no consideration was made to the space between the yarn feed roller an the package formed leading to the problem that the winding form of the package was unsatisfactory. The yarn winding machine comprises a contact roller (18) which rotates by contacting to the peripheral surface of the package (3), a yarn feed roller (26) which is provided to the upstream side of the contact roller (18) with a space (c) from the peripheral surface of the package (3), and rotates while contacting the yarn (Y) to the peripheral surface to supply the yarn (Y) to the package (3), a roller supporting member (1) for supporting the contact roller (18) and the yarn feed roller (26), and a roller supporting member position adjusting means for adjusting the position of the roller supporting member (1) in the direction the space (c) changes. In the yarn winding machine, contact roller (18) is supported capable of being displaced relative to the roller supporting member (1) in the direction the space (c) changes. The contact roller (18) is supported capable of being displaced relative to the roller supporting member (1), and a control means (30) is provided for controlling the roller supporting member position adjusting means so that the space (c) is to be constant irrespective of the package diameter (Fig. 2). <IMAGE>
