Method and apparatus for cutting strand

摘要

A strand cutting apparatus includes a fixed blade 2 having a blade edge extending perpendicularly with respect to the traveling direction of a strand, and a rotation blade 3 which is fixed to the tip portion of a rotation shaft 13 extending perpendicularly to the blade edge of the fixed blade 2 and has a plurality of plate-shaped blades 15 disposed radially at a front surface 3a. The rotation shaft 13 is supported by a supporting member 14 through a bearing mechanism 30 so as to be freely rotatable. The supporting member 14 is opposed to the one side of the fixed blade 2 with a clearance therebetween. The supporting member 14 is guided by a pair of guide plates 39 so as to be movable freely and linearly along the same direction as the axial direction of the rotation shaft 13. The rotation blade 3 is moved linearly to this same direction together with the supporting member 14 to adjust a clearance between the blade edge 2a of the fixed blade 2 and the blade edges 15a of the plate-shaped blades 15, and then the supporting member can be fixed by using stop bolts 41.
