Pirn Winding for Shuttle Weaving
topic
Pirn winding machines build the conical or parallel cheese weft packages used in shuttle looms by winding yarn at precise tension from cone or cheese supply packages onto small pirn forms with defined tip and chase build geometry that determines the unwinding balloon diameter and tension variation during weft release in the shuttle, with pirn capacity and winding density controlling the frequency of pirn change required during weaving.
Role
Produces the weft insertion packages required for shuttle weaving operations that remain in use for specialty technical and medical textiles requiring the even weft tension of shuttle insertion that rapier and air jet systems cannot match for certain sensitive yarn types, with pirn winding quality including tip uniformity and chase build accuracy being critical for consistent weft tension and shade uniformity in shuttle-woven fabrics.
