Claims (1)

[Claims for Utility Model Registration] (1) A blade that is pressed against the side surface of a bobbin with residual yarn and moves relatively in the axial direction to scoop up residual yarn from the side surface of the bobbin, and the scooping angle can be adjusted; A rotating cutter that cuts the scooped up remaining yarn,
A residual yarn removing device on a bobbin, comprising a suction duct that sucks cut residual yarn. (2) Claim 1 of the above utility model registration, wherein the blade is supported on a fixed side, and the bobbin stands up with respect to the blade and moves relative to the blade in the axial direction by an elevating mechanism. A device for removing thread remaining on a bobbin as described in 2. (3) The residual yarn removal device on a bobbin according to claim 1, wherein the blade is pressed against the bobbin by a cylinder so as to be able to move toward and away from the bobbin, and the rake angle is adjusted by an actuator. (4) The bobbin according to claim 1 of the utility model registration claim, wherein the bobbin is configured to be rotated by a rotating mechanism so that the suction duct can strip off the cut remaining yarn wound around the outer periphery of the bobbin.
