Apparatus for forming a yarn package

Abstract

Apparatus for forming a yarn package wherein the yarn package includes a plurality of axially stacked revolutions of yarn with each revolution formed to include a plurality of sinuous shaped wave patterns in each revolution, and wherein the sinuous pattern of adjacent revolutions are angularly offset relative to each other to form a yarn package having high porosity in the package to permit the ready flow of yarn treatment material therethrough. The yarn package forming apparatus includes a frame support means having a power driven turntable, with a pressure plate non-rotatably supported thereabove for vertical translating movement, and wherein the yarn package is formed between the rotatable turntable and the pressure plate. The yarn packaging apparatus is provided with a variable speed radially reciprocating yarn guide means for feeding the yarn through a radial slot in the pressure plate to the turntable for forming revolutions of yarn having the sinuous pattern, with each revolution having an adjusted length of yarn. The variable speed radially reciprocating means is provided with a programable speed adjustment mechanism which is operated at a number of independent speeds for a series of revolutions, with the sequence of rotational speed being repeated after a predetermined number of revolutions of the turntable. A yarn package is formed by threading a length of yarn through the yarn guide means and slot, engaging an end of the yarn with the rotary turntable and effecting rotation of the turntable to form the stacked revolutions of yarn which will in turn force the pressure plate upward as the yarn package is formed. An open mesh yarn bag is supported on the turntable with the bag being constructed of net material which will permit ready impregnation of a dye throughout the yarn package.
