Patent number: 5738007Abstract: A calender employs an open-stack like arrangement with a single vertical beam or support column on each end of the calender. In combination with the support beam, a special swing link is used to support tension loads on the open side of the calender. The nip is thus straddled by structural members between the support column and the link. This combination has the ability to support high linear nip loads, as high as 3,000 PLI or higher. The link has pin connections at both ends so that when one pin is removed, the link can be swung open for roll removal or accessibility. Thus, the strength of the closed-stack calender is combined with the visibility and ease of access of the open-stack calender by the employment of tension links which replace one of the support columns utilized in a closed-stack calender.Type: GrantFiled: March 12, 1996Date of Patent: April 14, 1998Assignee: Beloit Technologies, Inc.Inventors: Arnold J.

Patent number: 5711854Abstract: A roll press including at least two rolls forming a press nip for the treatment of a web of material. A press roll includes a very flexible roll shell which is rotatable around a stationary support. The roll shell is mounted by at least one support element on the support. The support element has a concave support surface which forms a wide press nip with the backing roll. This provides a roll press which, even in the case of a backing roll which is without sag control, defines a press nip which is very substantially uniform. This is achieved by having the outer circumference of the shell of the press roll change in dimension in the axial direction from the axial center of the roll towards the ends of the roll, i.e., the outer circumference may increase or decrease. The circumference of the backing roll may or may not correspondingly change in the axial direction.Type: GrantFiled: May 31, 1996Date of Patent: January 27, 1998Assignee: Voith Sulzer Papiermaschinen GmbHInventors: Christian Schiel, Rainer Bentele, Wolf Gunter Stotz

Patent number: 5699729Abstract: A roll system for use particularly in a papermaking press nip for dewatering a fibrous web, comprising a roll disposed so as to rotatingly cooperate with another roll in a press nip, the roll having a helical sensor for sensing pressure exhibited on the roll, and transmitting pressure signals to a processor as the roll rotates. Trigger signals are generated at certain times as the roll rotates, the time of the occurrence of the trigger signal representing a specific location on the helical sensor. The pressure signals are coordinated with the trigger signals, such that the pressure corresponds to the angular position of the roll where it is sensed. The operator may thus be given a visual or audible indication of the existence of non-uniformities in pressure sensed at various locations along the roll, thereby enabling corrective action to be initiated if necessary.Type: GrantFiled: September 30, 1996Date of Patent: December 23, 1997Assignee: Stowe Woodward CompanyInventor: Charles Moschel

Patent number: 5582099Abstract: A truss bend correction system having a pair of in-feed correction rollers, a pair of finish rollers, and an out-feed correction roller define a path for counterbending the joints of a truss to reform the nail plates and thereby flatten the overall truss. The in-feed correction rollers and the out-feed correction roller are oriented downwardly with respect to the finish rollers so that an undesired upward bow of a truss joint is counterbent downwardly, thereby straightening the joints of the truss.Type: GrantFiled: May 26, 1995Date of Patent: December 10, 1996Assignee: Alpine Engineered Products, Inc.Inventor: Michael C.

Patent number: 5562790Abstract: An apparatus and method for bonding at least two continuously moving substrate webs together is disclosed. The apparatus comprises a rotatable bonding roll which is located adjacent the substrate webs and configured to rotate about a bonding axis. A rotatable anvil roll has an anvil surface and is configured to rotate about an anvil axis to press the substrate webs against an outer peripheral bonding surface of the bonding roll thereby bonding the substrate webs together. The anvil roll is pivotally connected to a pivotal support mechanism which is configured to maintain the anvil surface in a substantially parallel relationship with the bonding surface. The pivotal support mechanism is configured to allow the anvil roll to pivot such that the anvil roll maintains a substantially constant force on the bonding surface of the bonding roll across the width of the anvil roll.Type: GrantFiled: May 18, 1995Date of Patent: October 8, 1996Assignee: Kimberly-Clark CorporationInventors: Thomas D. Ehlert, Norman R. Stegelmann

Patent number: 5562027Abstract: A system for measuring the dynamic pressure distribution between rolls in a nip roll press comprises a roll adapted to rotatingly contact at least one other roll in a press nip, having one or more sensors thereon, for measuring the nip pressure at several locations along the roll length, wherein the measurements obtained by the sensors are transmitted to a computer and a display, to provide tabular, numerical and graphical representations of the pressure at one or more locations on the roll. Optionally a control system may be incorporated in the system for determining the pressure distribution along the roll and initiating corrective measures. The system of the instant invention can further measure temperature variations, if desired, as thermal sensors can be used on the sensing roll, or a computerized correlation scheme can relate sensor readings to temperature as well as pressure.Type: GrantFiled: February 16, 1995Date of Patent: October 8, 1996Assignee: Stowe Woodward Licensco, Inc.Inventor: Robert H. Moore

Patent number: 5560410Abstract: A system (10) for processing veneer is provided. The system (10) includes a compression apparatus (12) having a first set of rollers (20) turning at a first rate and has a first clearance (96) therebetween, and a second set of rollers (22) turning at a second rate and has a second clearance (98) therebetween. The first and second roller rates are substantially equal. The system also includes a feeder (16). The feeder (16) includes a hopper (62) for holding a plurality of veneer slats (82) and a feeder mechanism for feeding the slats one at a time into the compression apparatus. The system may have a first drive mechanism (14) for turning the first (20) and second (22) rollers and a second drive mechanism for driving the feeder mechanism.Type: GrantFiled: October 11, 1994Date of Patent: October 1, 1996Inventor: Anthony N. Peacock

Patent number: 5547002Abstract: A press machine having a frame with a central channel projecting along a length thereof. The channel slidably guides a piece of lumber along a processing path. Press wheels are mounted to longitudinal supports extending along opposite sides of the central channel. One of the longitudinal supports is pivotally mounted at one end to the frame with a corresponding press wheel rotatably mounted at an intermediate point along the support. The press wheels are oriented to rotate about parallel axes and in opposite directions with adjacent sides thereof overlapping opposite sides of the processing path. The press wheels are spaced apart from one another such that adjacent arcuate portions of each press wheel are located immediately adjacent the processing path to frictionally engage a leading end of a piece of lumber conveyed along the processing path.Type: GrantFiled: June 6, 1995Date of Patent: August 20, 1996Inventor: Larry J. Runnebaum

Patent number: 5529100Abstract: A veneer dehydrating apparatus is disclosed which is intended to squeeze out part of water contained in green softwood veneer. The apparatus includes a pair of parallel rolls assemblies rotatable in opposite directions and disposed one above the other to be spaced apart from each other thereby to define an open nip between the circumferential peripheries thereof, and a conveyer for feeding successively sheets of green softwood veneer with the fiber orientation thereof directed along the feeding direction into said nip. One of the roll assemblies has formed on the peripheral surface thereof a number of individual projections pierceable into said veneer sheet at the nip. Each projection has a pyramidal shape with N faces, wherein N represents an integral number of four or more.Type: GrantFiled: December 19, 1994Date of Patent: June 25, 1996Assignee: Meina Machinery Works, Inc.Inventor: Yoshinori Koba
