Abstract:
1. A continuous web cutting apparatus for cutting a continuous web that has a plurality of fibers including tows along a predetermined direction, the continuous web being cut at intervals in the predetermined direction while being transported along a predetermined track in the predetermined direction, comprising: a disc-shaped rotatable blade member positioned for cutting the continuous web by moving in an intersecting direction that intersects the predetermined direction, while rotating about an axis of a rotating shaft along the predetermined direction without the rotatable blade member engaging an opposing member; a regulating section that regulates a relative movement of the continuous web in the predetermined direction with respect to the rotatable blade member throughout a time during which the rotatable blade member is cutting the continuous web; and a reciprocating mechanism that moves both the rotatable blade member and the regulating section along a forward path and a return path that are parallel to the predetermined track; wherein, in the forward path, an equal velocity region is set in which both the rotatable blade member and the regulating section move at a velocity value that is equal to a transport velocity value of the continuous web, and the rotatable blade member cuts the continuous web while moving in the equal velocity region.
