Abstract

In a yarn winding apparatus, the state of a yarn is accurately detected with a simple structure.In a traverse guide, a guide rail 63 arranged to guide a yarn which is being traversed is conductive or intermediate-conductive at least at a contact portion with the yarn. A static electricity quantity detection circuit 51 outputs a signal corresponding to the quantity of static electricity generated in the guide rail 63 due to the contact between the yarn and the guide rail 63. When the maximum change quantity ΔE of the static electricity quantity indicated the signal output from the static electricity quantity detection circuit 51 during a period from a time point before a predetermined time to the present is equal to or less than a threshold ΔEa (S102: YES), a controller 52 outputs a first signal which indicates that the state of the yarn at the guide rail 63 is a predetermined state (S103). When the maximum change quantity ΔE is above the threshold ΔEa (S102: NO), the controller 52 outputs a second signal which indicates that the state of the yarn at the guide rail 63 is not the predetermined state (S104).
