  • the present invention relates to a cutting device for a web member having a plurality of fibers including tows, and a cutting method.
  • Patent Document 1 a cleaning web member in which a handle member is inserted so that it can be used for cleaning a desktop or the like.
  • a cleaning web member has a main body in which a plurality of fibers are laminated on a base sheet, and a long fiber of thermoplastic resin called tow is used as the fiber.
  • a semi-finished product is obtained by fixing a plurality of tows with the fiber direction along the predetermined direction to the base sheet by welding or the like to the base sheet continuous along the predetermined direction.
  • a web member continuous in a predetermined direction is generated, and finally the web member is cut in a width direction intersecting the predetermined direction to produce a single-sheet cleaning web member.
  • the cutting device of Patent Document 2 it is conceivable to use the cutting device of Patent Document 2.
  • the web member is cut between the cutter roll having the cutter blade on the outer peripheral surface and the anvil roll having the receiving blade for receiving the cutter blade, and being clamped by the cutter blade and the receiving blade. Can be considered.
  • the tow relating to the above-mentioned web member is thermoplastic, due to the clamping pressure between the cutter blade and the receiving blade at the time of cutting, the tows at the position to be cut are easily welded or pressed together. There is a possibility that the performance as a brush portion (performance for removing dust at the time of cleaning) may deteriorate due to binding of the cut edge in a bag-like shape. Moreover, if the cut end edge is bound in a bag-like shape, the bulk of the cleaning web member becomes small, which also leads to a reduction in the performance of the brush portion. Furthermore, due to the contact between the cutter blade and the receiving blade at the time of cutting, the cutting edge of the cutter blade is likely to be worn, and the life of the cutter blade may be reduced.
  • the width direction of the web member while driving and rotating a rotary blade having a plurality of concave portions at the edge of the outer peripheral edge about the rotation axis along the predetermined direction It can be considered that the web member is cut by moving along the web. And according to this method, in addition to the high cutting performance due to the drive rotation of the rotary blade, the cutting is promoted by hooking the tow into the concave portion, so that the cutting can be reliably performed only by hitting the rotary blade against the web member. As a result, the rotary blade does not require a receiving blade for clamping the web member during cutting.
  • the cut tow or the like fiber is a disk-shaped rotary blade from immediately after cutting the fiber to the completion of the cutting of the web member by the rotary blade. Therefore, the rotation of the board surface unwinds in the thickness direction of the web member, and the fibers near the cutting position of the web member can be made soft and bulky. Therefore, it is possible to provide a single-cut product related to the cut web member, that is, a cleaning web member in a bulky state.
  • the present invention has been made in view of the above-described conventional problems, and an object of the present invention is to use a rotary blade to replace a web member having a plurality of fibers including tows in a predetermined direction.
  • the tow is prevented from entering a plurality of recesses formed in the cutting edge of the rotary blade, thereby preventing the accumulation of molten iron from the tow at the cutting edge.

  • a plurality of concave portions are formed side by side along the circumferential direction of the rotary blade member at the edge of the outer peripheral edge of the rotary blade member, An average value of the circumferential lengths of the plurality of concave portions is smaller than an average value of diameters of the tows included in the web member.
