Abstract (en)
The yarn length measuring device includes: a means (73) that detects a yarn layer peripheral surface movement distance PLs of a yarn layer formed by the winding yarn (4) around a winding tube (6) ; a means (74) that detects a traverse movement distance TLs of the yarn; and a winding length computing means (75) that inputs the yarn layer peripheral surface movement distance PLs, and the traverse movement distance TLs, detected by the traverse movement distance computing means (74), calculates a winding length of the yarn (4) wound around the winding bobbin (6, 7) at each time (Ts) from the TLs and the PLs that have been input, and determines a winding length (YL) of the yarn (4) wound around the winding bobbin (6, 7) by summing up the winding lengths YL calculated at each predetermined time (Ts).
