Patent number: 10251525Abstract: A method for forming compression-bonding portions in a continuous body including a fiber bundle while conveying the continuous body includes: rotating a rotator to convey the continuous body; compressing a target part of each of the compression-bonding portions in the continuous body using a first compression-bonding apparatus and the rotator to form the compression-bonding portions of a first stage; and further compressing each of the compression-bonding portions of the first stage using a second compression-bonding apparatus and the rotator to form the compression-bonding portions of a second stage. At least one of the compression-bonding portions is positioned between the first compression-bonding apparatus and the second compression-bonding apparatus in the direction of rotation of the rotator when the second compression-bonding apparatus compresses the compression-bonding portion of the first stage.Type: GrantFiled: November 28, 2014Date of Patent: April 9, 2019Assignee: UNICHARM CORPORATIONInventors: Kazuhiko Hoshika, Yoshihide Ishikawa, Hisaoki Nobukuni

Patent number: 9486991Abstract: There is provided a manufacturing apparatus for manufacturing a cleaning web member by intermittently cutting a continuous web member at a product pitch in a transport direction, the continuous web member having a base sheet continuous in the transport direction and a fiber bundle placed on and secured to the base sheet with a direction of fibers being along the transport direction. The manufacturing apparatus includes: an intermittent transport mechanism; a cutter mechanism; a sensor; and a control section. The control section controls a transport amount related to the intermittent transport by the intermittent transport mechanism based on information of the displacement amount output from the sensor.Type: GrantFiled: December 28, 2012Date of Patent: November 8, 2016Assignee: UNICHARM CORPORATIONInventor: Hisaoki Nobukuni

Patent number: 9067328Abstract: The invention relates to a cutting device which cuts a web member, which includes fiber bundles which extend continuously in a machine direction MD and which is intermittently conveyed in said machine direction, in a crossing direction CD which crosses the machine direction. The cutting device has a plurality of disk shaped rotary blades which rotate about rotary shafts which extend along the machine direction while moving in said cross direction so as to thereby cut said web member when the web member is at a stop. The plurality of rotary blades are arranged so as to be substantially aligned in the crossing direction and includes a rotary blade which rotates in one direction and a rotary blade which rotates in the opposite direction.Type: GrantFiled: January 25, 2013Date of Patent: June 30, 2015Assignee: UNICHARM CORPORATIONInventors: Kunihiko Saito, Shigetomo Takahashi, Kazuhiko Hoshika, Hisaoki Nobukuni

Patent number: 9050731Abstract: Disclosed is an apparatus for cutting a web member along an intersecting direction. The web member has a plurality of fibers including tows along a predetermined direction intersecting the intersecting direction. The apparatus includes a disc-like rotatable blade member for cutting the web member by relatively moving in the intersecting direction with respect to the web member while rotating about a rotation shaft, the rotation shaft extending along the predetermined direction, the rotatable blade member including a cutting edge on an outer circumferential edge portion thereof, a plurality of recess portions being formed on the cutting edge, the plurality of recess portions being arranged along a circumferential direction of the rotatable blade member, a mean value of lengths of the plurality of recess portions in the circumferential direction being smaller than a mean value of diameters of the tows contained in the web member.Type: GrantFiled: January 31, 2013Date of Patent: June 9, 2015Assignee: UNI-CHARM CORPORATIONInventor: Hisaoki Nobukuni

Patent number: 9003937Abstract: An apparatus for cutting a continuous web includes a disc-shaped rotatable blade member for cutting the continuous web by moving in an intersecting direction, while rotating about an axis of a rotating shaft, a regulating section for regulating 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 for moving both the rotatable blade member and the regulating section along a forward path and a return path. The forward path has an equal velocity region where both the rotatable blade member and the regulating section move at a velocity value equal to a transport velocity value of the continuous web. The rotatable blade member cuts the continuous web while moving in the equal velocity region.Type: GrantFiled: January 31, 2013Date of Patent: April 14, 2015Assignee: Unicharm CorporationInventor: Hisaoki Nobukuni
