| 4 | Band saw for cutting multiple boards simultaneously | EP99630009.1 | 1999-01-19 | EP0930138A2 | 1999-07-21 | Baker, Edward L. |
The resaw (1) includes a frame (3) having at least one head (25). The head includes a horizontal mounting beam (43) with four wheels (57,59,61,63) operatively mounted to the mounting beam (43). The wheels comprise an inner pair of wheels (61,63) and an outer pair of wheels (57,59). The centers of the inner wheels are vertically offset from the center of the outer wheels. A band saw blade (29) is mounted about the four wheels to define a first blade portion (65) and a second blade portion (67) which are spaced from each other. A single head (25) can simultaneously make two slices in a cant (19) to cut two or more boards from the cant. The inner and outer wheels can be moved as a unit relative to the path of travel of a cant and the inner wheels can be moved relative to the outer wheels to enable adjustment of the thickness of the boards cut from the cant. In variations, the resaw can have two heads (25,27) and each head can have one, two, or more blades (29,31). With a two head resaw, four slices can simultaneously be made in the cant. Where each of the two head resaw has two band blades, eight slices can simultaneously be cut in the cant. |

| 6 | Bi-directional cutting band mill | US10365292 | 2003-02-12 | US06722248B1 | 2004-04-20 | Dwight H. Johnston, Sr. |
| A bi-directional cutting band mill apparatus utilizes two band saws mounted on a carriage for cutting horizontal sections from logs through successive back and forth passes across each log as the carriage reciprocates on a lower frame wherein a section of the log is cut with one band saw in one pass and then a next section of the lumber is cut by the other band saw as the carriage travels in the opposite direction in the following pass. The bi-directional cutting band mill apparatus includes structural elements that allow for the coincident raising and lowering of both band saws and structural elements that provide for the sequential and incremental adjustment of each band saw preparatory for cutting the sections from the log so that each respective band saw can be positioned for making the appropriate depth of cut through the section of the log during that respective pass of the respective band saw. | ||||||

The method allows for maximal recovery of high-quality lumber. | ||||||
| 8 | Device for producing square beams from tree trunks | US09544607 | 2000-04-06 | US06325119B1 | 2001-12-04 | Johann Wolf; Dale Sanborn |
| To produce square beams from tree trunks (13), a device is proposed in which a tree trunk (13) is first positioned by a centering device (4) such that the lengthwise axis (14) of the tree trunk (13) assumes essentially always the same stipulated position. The tree trunk (13) is then grasped by holders (11, 12) of a carriage (8) concentrically to the lengthwise axis (14), whereupon the centering device (4) is opened. Then the tree trunk (13) is guided through a band saw (5) and trimmed on the opposite sides, whereupon it is turned by 90° and the two other sides of the tree trunk (13) are trimmed. | ||||||
| 9 | Horizontal band saw device having multiple lanes of travel and associated method | US09086056 | 1998-05-28 | US06244144B1 | 2001-06-12 | Douglas William Goldie |
| A horizontal band saw device for cutting lengthwise along boards passed therethrough enables increased cutting capacity of such boards and includes a head with both a first board conveyor passing therethrough and a second board conveyor passing therethrough. The head includes an inlet end, an outlet end, a board receiving passage, and a movable band saw blade, the board receiving passage having the movable band saw blade passing from a first side to a second side thereof. The first board conveyor extends through the board receiving passage of the head and beneath the band saw blade. The second board conveyor extends through the board receiving passage of the head and beneath the band saw blade, the second board conveyor being spaced from the first board conveyor. The first board conveyor is operable to continuously feed a first board resting thereon through the board receiving passage at a set speed and the second board conveyor is operable to continuously feed a second board resting thereon through the board receiving passage at the set speed such that the first board and the second board are simultaneously cut along their respective lengths by the band saw blade thereby at least doubling the board cutting capacity of the horizontal band saw device as compared to a band saw device including only one board conveyor operating at the set speed. Each board conveyor defines a lane of travel of the band saw device and more than two lanes of travel may be provided. | ||||||
| 10 | Multiple bandmill for making a plurality of sawlines in the same longitudinal plane at one time | US297786 | 1989-01-17 | US4864905A | 1989-09-12 | Jeanne D. Danielson; David D. Lewis |
| A multiple bandmill (10) for sawing a log (L) moving past that multiple bandmill. This multiple bandmill includes two pairs of bandmills (20, 22 and 24, 26) located at a common longitudinal position with respect to a log being cut. The bandmills comprising the multiple bandmill are slanted with respect to vertical in the longitudinal direction. The bandsaw blades (50, 52 and 54, 56) of each pair of bandmills within the multiple bandmill cross each other in a X-pattern in the log cutting region (30). One bandmill (20, 26) of each pair is located within the area defined by the other bandmill (22, 24). All four sawlines (12, 14, 16, 18) are made at the same time at a single longitudinal location on the log. | ||||||
| 11 | Apparatus for edging and resawing lumber | US3687269D | 1969-12-15 | US3687269A | 1972-08-29 | FRITZ RENE; FRITZ RENE EUGENE |
| A battery of vertical band saws is adjustable to vary the spacing between bands and is used to both edge and resaw material. A preparation table upstream from the saws receives material from a recirculating conveyor or from a head rig, orients the material in the most desirable position for cutting and transfers the material endwise to an infeed table. The infeed table has toothed conveyor rolls for feeding the material positively into the saws, an overhead pneumatic roll for engaging the top of the material while edging and driven side press rolls for pressing the material against a line bar when resawing. Downstream from the saws an edge picker table has a pair of longitudinal separating plates normally aligned with the two outside saws for separating edge trimmings from the material to be processed into lumber. The plates are withdrawn from alignment with the saws when resawing. A sweep table receives material from the edge picker table and includes sweep fingers which sweep across the table for transferring material sideways to the recirculating conveyor and pivot downwardly to permit transfer of material endwise from such table.
