Abstract
An apparatus for winding a synthetic-resin yarn on a spool of predetermined outside diameter has a friction drive roller rotatable about a drive axis and having a substantially cylindrical outer surface of predetermined length centered on the drive axis. A drive can rotate this roller about the drive axis at a substantially constant speed. A support adjacent the friction roller holds the spool for rotation about a spool axis generally parallel to the drive axis and with the spool in radial contact with the surface of the drive roller. A radially outwardly projecting ridge carried on the support axially offset from the surface of the friction roller is of greater outside diameter than the spool. Guides feed the yarn initially to the ridge for winding of the yarn thereon and thereafter for feeding the yarn to the spool for winding of the yarn on the spool.
