Patent number: 6592698Abstract: A method of forming sheet rolls made of a heat transfer recording sheet having a transfer ink layer on a surface of a base by winding the recording sheet around the outer peripheries of a plurality of cores. The method includes supplying a web heat transfer recording sheet, cutting a portion thereof corresponding to a region between two adjacent sheet rolls to form cut ends, placing a non-adhesive waste sheet and a pair of adhesive tapes attached to the waste sheet ends between the transfer recording sheet, the tapes having an adhesive portion, an outside-exposed portion, and a portion attached to a cut end of the recording sheet, winding the sheet around a core outer periphery, positioning the waste sheet between winding apparatus and a discharging portion, and cutting the waste sheet so positioned.Type: GrantFiled: June 6, 2001Date of Patent: July 15, 2003Assignee: Dai Nippon Printing Co., Ltd.Inventor: Yoshikimi Semba

Patent number: 6527218Abstract: Winding device and process for winding wound rolls. The winding device includes a pressure roll axially divided into separate sections and a winding arrangement. The pressure roll is arranged to be placed on the winding arrangement. A coupling device is arranged to axially couple the separate sections together, and a drive unit is arranged to commonly rotatably drive the axially coupled separate sections. The process includes axially coupling the separate sections of the pressure roll together with the coupling device, rotatably driving the axially coupled separate sections, and pressing, at a beginning of a winding procedure, the separate sections of the pressure roll against the wound rolls.Type: GrantFiled: August 25, 2000Date of Patent: March 4, 2003Assignee: Voith Sulzer Papiertechnik Patent GmbHInventors: Dirk Cramer, Frank Schorzmann

Publication number: 20030001043Abstract: A contact roller system of a winding machine for thin strip material has a shaft and pivot levers arranged in a row adjacent to one another on the shaft. The pivot levers have two contact roller segments moveable against slit rolls during a winding process by an actuating drive of the pivot levers. The two contact rollers are arranged on opposite sides of the pivot levers, respectively, and form a contact roller segment pair positioned adjacent to one another such that between neighboring end faces a gap required for rotational movement of the contact roller segment pairs is formed. The contact roller segment pairs are freely rotatably supported and rotate about an axis of rotation extending parallel to the pivot axis of the pivot levers. The axes of rotation of the contact roller segment pairs have a common pivot radius.Type: ApplicationFiled: June 27, 2002Publication date: January 2, 2003Applicant: WT Wickeltechnik GmbHInventors: Martin Frank, Dieter Pflitsch

Patent number: 6425547Abstract: A system for producing coreless fabric rolls includes a feed station (12) operable to supply a leading edge of a fabric web (24) from a parent roll (18). The system includes a first tucking station (132) operable to position the leading edge of the fabric web (24) adjacent one of a plurality of spindles (48, 50, 52) coupled to a turret (46). The system also includes a winding station (38) comprising a winding roller (36). The winding station (38) is operable to receive the leading edge in a nip defined by the spindle (48, 50, 52) and the winding roller (36) and wind the fabric web (24) into a fabric roll about the spindle (48, 50, 52). The system also includes a cutting station (40) operable to separate the fabric roll from a remaining portion of the fabric web (24). The system also includes a second tucking station (42) operable to receive the spindle (48, 50, 52) from the winding station (36) and wind a trailing edge of the fabric roll about the fabric roll.Type: GrantFiled: August 31, 1999Date of Patent: July 30, 2002Assignee: EthiconInventor: Balbir Singh

Patent number: 6283404Abstract: A material transfer system is disclosed using a hollow cylindrical lock shaft for rewinding flexible material from an original core to at least one transfer core. The shaft has an interior and exterior wall, a length, and at least one curved locking base recessed along the length. The bases have a first and second wall with a floor having a progressively decreasing radius from the first to the second wall. Multiple legs extend radially inwardly from the interior wall and have gripping feet are at their distal ends. A plurality of locking ribs extend the length of the locking bases and are affixed to the floor at the each end of the rib. The locking ribs have a diameter sufficient to enable the locking rib outer circumference to extend beyond the circumference of the shaft exterior. At least one locking strip is affixed to at least a portion of the shaft's length, extending beyond the circumference of the exterior wall to prevent the cores from moving freely.Type: GrantFiled: March 31, 1999Date of Patent: September 4, 2001Inventor: Emile Fournier

Patent number: 6269859Abstract: A sheet roll forming system for forming sheet rolls by winding a heat transfer recording sheet around an outer periphery of a plurality of cores including a core supplying apparatus and a sheet roll discharge apparatus. The core supplying apparatus includes a cantilever shaft supporting the cores, a tray below the shaft and movable up and down in a direction of the shaft, and core stoppers on the tray where the shaft is an air shaft that can increase in diameter when air is supplied from a charge and exhaust apparatus. The sheet roll discharge apparatus includes the shaft supporting rolls of the recording sheet on the cores, a tray below the shaft, and a stopper on the tray.Type: GrantFiled: July 9, 1998Date of Patent: August 7, 2001Assignee: Dai Nippon Printing Co., Ltd.Inventor: Yoshikimi Semba

Patent number: 6182919Abstract: In winding machine for winding running webs of material, for instance paper webs or plastic foil, contact roller systems are known which have several roller segments arranged next to each other with their frontal sides, and which are supported to rotate freely and be perpendicularly movable with respect to their rotation axis. Each roller segment is held by a frame, which is supported to move perpendicularly to the rotation axis. Each frame of a roller segment comprises two lateral support plates extending parallelly to their frontal sides, whereby the neighboring support plates of two roller segments are arranged one above the other perpendicularly to the motion direction. The support plates can have deep annular grooves wherein the frontal faces of the roller segments can rotate free of touch.Type: GrantFiled: September 17, 1999Date of Patent: February 6, 2001Assignee: Kampf GmbH & Co.
