Web member cutting apparatus for cutting web member that has a plurality of fibers including tows and web member cutting method

摘要

A web-member cutting apparatus for cutting a web member at intervals in a transport direction includes: an intermittent transport mechanism for intermittently transporting the web member in the transport direction; a disc-like rotatable blade member for cutting the web member by moving along an intersecting direction while rotating about a rotation shaft during a suspension period of transport of the web member, and a downstream pressing member for regulating movement of the web member by pressing the web member against the intermittent transport mechanism at a position downstream from a target cut position in the transport direction throughout a period during which the rotatable blade member is cutting the web member.

1. A web-member cutting apparatus for cutting a web member at intervals in a transport direction,
the web member having a plurality of fibers including tows along the transport direction and being continuous in the transport direction, the web-member cutting apparatus comprising: an intermittent transport mechanism for intermittently transporting the web member in the transport direction; a disc-like rotatable blade member positioned for cutting the web member by moving along an intersecting direction while rotating about a rotation shaft during a suspension period of transport of the web member without the rotatable blade member engaging an opposing member,
the intersecting direction intersecting the transport direction,the rotation shaft extending along the transport direction; and a downstream pressing member that regulates movement of the web member by pressing the web member against the intermittent transport mechanism at a position downstream from a target cut position in the transport direction throughout a period during which the rotatable blade member is cutting the web member.
