Publication number: 20020038588Abstract: A lumber trimming device for trimming elongate workpieces conveyed on an infeed conveyor in a laterally disposed orientation relative to an infeed direction. The lumber trimming device includes a gang of laterally spaced apart drop saws wherein the drop saws are independently actuable according to generally optimized trimming instructions from an optimizer. At least on end-trimming saw is mounted adjacent the gang. The end-trimming saw or saws is or are selectively laterally translatable according to optimized end-trimming instructions from the optimizer so as to cooperate with the gang. The end-trimming saw or saws cooperate with the optimizer and the drop saws so that a first drop saw of the drop saws is actuated simultaneously with optimized lateral positioning of a first end-trimming saw so as to trim a first workpiece of the workpieces on the infeed conveyor simultaneously by both the first drop saw in a first trim cut and the first end-trimming saw in a second trim cut.Type: ApplicationFiled: September 26, 2001Publication date: April 4, 2002Inventors: William R. Newnes, Deane R. Henderson, Paul L. Halper

Publication number: 20020007710Abstract: A board trimmer having pre-trimmer saws includes a selectively translatable upstream first pre-trimmer saw mounted on a near-side of a board flow path of a board transfer, upstream of a downstream multi-saw board trimmer. The pre-trimmer saw is selectively translatable by an actuator for translation linearly parallel to a near-side ended board on the board transfer. The pre-trimmer saw is perpendicular to the board when on the board transfer. A board elevator may be mounted below the board flow path and the pre-trimmer saw for elevating the board from a sequence of single boards from the board transfer into sawing engagement with the pre-trimmer saw once the pre-trimmer saw has been prepositioned by the actuator into an optimized cutting path. Trimming of the board in the flow path is done according to an optimized solution for trimming the board.Type: ApplicationFiled: July 24, 2001Publication date: January 24, 2002Inventor: William R. Newnes

Patent number: 6279441Abstract: A log processing system contains a row of tipple units for supporting a log to be cut into programmed lengths by saws swing-mounted on carriages selectively positioned on a truck extending beside said row. Each tipple unit has two oppositely extending wings each independently moveable between upwardly sloped and downwardly sloped positions. The tipple units at the cutting positions have their wings lowered out of the cutting range of the saws. Log hold-down arms operate from the carriages in conjunction with the saws.Type: GrantFiled: February 16, 2000Date of Patent: August 28, 2001Assignee: Nicholson Manufacturing CompanyInventor: Bernhard H.

Patent number: 6253652Abstract: In a web slitter of the type used for cutting continuous webs of material, such as paper, a top slitter assembly features a hub cylinder attached to its frame. The hub cylinder supports a freely rotating hub to which the top blade of the web slitter is mounted. The hub cylinder may be raised and lowered with respect to the slitter frame so that the top blade may be lowered to, and raised from, its cutting position. A toggle support is clamped to the hub cylinder while a pin holder is attached to the slitter frame. A toggle is attached to the toggle support in a pivoting fashion. Housed within the pin holder is a sliding pin and a compression spring. The compression spring resists the movement of the pin towards the hub of the web slitter. The pin may be extended so that it engages a notch in the hub. When the hub cylinder is raised, the toggle may be pivoted so that it abuts the end of the engaged pin against the action of the compression spring. As a result, the pin is maintained in engagement with the hub.Type: GrantFiled: November 25, 1998Date of Patent: July 3, 2001Assignee: Valmet CorporationInventors: James Dax, Jeffrey Knutson

Patent number: 6247389Abstract: A polymer cutter with a rotary cutting head in which the cutting edges are on the circumferential periphery of the head, and in which the cutting edges shear rather than slice the polymer is described. The knife blades on the rotary head have a cutting edge angle of greater than 70°. The apparatus is especially useful for cutting thermoplastics and may be used for preparing polymer granules or pellets.Type: GrantFiled: January 7, 2000Date of Patent: June 19, 2001Assignee: E. I. du Pont de Nemours and CompanyInventors: Michael Robert Samuels, Marion Glen Waggoner

Patent number: RE40349Abstract: A device for cutting wood or other materials comprises a saw blade clamping device for radially and/or axially fixing circular saw blades mounted axially displaceable on a drive shaft. Support bodies are provided axially displaceable on the drive shaft for each circular saw blade. The axial displacement of the circular saw blades takes place by guide spindles running parallel to the axis of the drive shaft and passing through the support bodies. At least one clamping element is mounted in the drive shaft 1, 20. The clamping element is mounted radially displaceable. In a first stage, the circular saw blades which are mounted on the support bodies are thereby displaced. In a second stage, the circular saw blades or support bodies are connected to the drive shaft in keyed and/or force locking engagement. Through the device, a displacement of the cutting width is possible without the time and labor intensive dismantling of the saw blades.Type: GrantFiled: March 16, 1998Date of Patent: June 3, 2008Assignee: Raimann Holzoptimierung GmbH & Co.
