Abstract:
A strand cutting apparatus comprising:a fixed blade having a blade edge extending perpendicularly with respect to a traveling direction of a strand;a supporting member opposing to one side of said fixed blade with a clearance therebetween;a rotation shaft supported by said supporting member through a bearing mechanism so as to be freely rotatable and extending perpendicularly to said blade edge of said fixed blade;a disc-shaped rotation blade provided integrally at a tip end of said rotation shaft,a plurality of guide grooves provided radially on a front surface of said rotation blade opposing to said blade edge of said fixed blade, andplate-shaped blades respectively disposed in said guide grooves so that an amount of protrusion of each of blade edges of said plate-shaped blades is freely changed;guide means for guiding said supporting member to be movable freely and linearly along a same direction as a axial direction of said rotation shaft, said rotation blade integrally provided at a tip end of said rotation shaft being linearly moved together with said supporting member to said same direction as said axial direction of said rotation shaft so that a clearance between said blade edge of said fixed blade and said blade edges of said plate-shaped blades is to be adjusted.
