Abstract
A system and method of providing electrostatic pick-up of yarn on a rotating carrier tube or the like involving provision and use of an electrostatic generator for the application of a static charge to the leading section of the yarn which is subsequently directed across a spindle mounted rotating carrier in a manner whereby the yarn is adhered to or picked up on the tube by electrostatic attraction, the continuous high speed rotation of the carrier effecting a quick positive achievement of multiple wraps of yarn about the carrier.
Claims4
A method of adhering the yarn to and winding yarn on a rotating yarn carrier comprising applying a static charge to the yarn and directing the charged yarn into sufficiently close proximity to surface contact with the rotating carrier to electrostatically adhere the yarn to the carrier during at least the initial wraps of the yarn about the carrier.
A yarn pick-up system comprising a source of infeeding yarn, yarn handling means outward of said source, a carrier mounting spindle interposed between said yarn feeding source and said yarn handling means, and means for generating an electrostatic charge on yarn interposed between said yarn feeding source and said spindle along the path of movement of yarn between the source and spindle.
