(54) Hairiness reducing device and yarn winding device


(57) A hairiness reducing device includes multiple pairs of press-contact members arranged along a yarn path of a yarn being wound on the winding unit. Each pair of the press-contact members is formed by a first press-contact member that includes a first yarn contacting portion and a second press-contact member that includes a second yarn contacting portion arranged with the yarn path interposed therebetween. At least one of a set of first press-contact members and a set of second press-contact members includes a moving mechanism for moving one of the sets relative to the other set. The yarn contacting portions retain the yarn by sandwiching the yarn. In each pair of the press-contact members, the first yarn contacting portion is a protrusion arcuate along the yarn path, while the second yarn contacting portion is either a flat surface along the yarn path or a protrusion arcuate along the yarn path.
