摘要： An automated multiple rip sawing apparatus is disclosed, wherein the boards are inspected at an inspection station to identify the lateral boundaries of the maximum usable clear area of each board. Each board is then delivered to an elongated saw feeding table which includes a transversely movable guide fence, and the board is then fed through a multiple rip saw having blades of differing separations, to thereby form a plurality of separate wood components. The transverse movement of the fence is automatically adjusted by a computer control, which includes the stored value of the boundaries of the maximum clear area of the board, and so that the board is ripped into the number and size of wood components which achieves a maximum yield from each board. Also, the saw feeding table includes a fixed support frame, and guide means for supporting the transverse movement of the fence while maintaining a high degree of accuracy in its alignment with respect to the fixed support frame.

摘要： A system that rotatively orients and skew positions a log for lumber processing. A log is placed in centering V's and rough centered. Rotatable scan spindles rotate the log while scanners obtain measurements at spaced locations along the log length and at selected rotative positions. Each angular position is analyzed for an optimum cutting pattern and the spindles are rotated to rotate the log into the most desirable angular position. The log is skew adjusted by the scan spindles and/or knee clamps in a carriage and conveyed to a saw array. A computer controls the cutting action to achieve the selected cutting pattern.

摘要： A sawmill in which a multi-log supporting mechanism is constructed wherein logs are grasped at spaced angular positions about the mechanism and rotated by it between an initial receiving position to a profile measurement position and then to a sawing position. The end-to-end axis of the supporting mechanism is adjustably oriented with respect to a saw in terms of profile measurements and size of lumber determined to be cut from a log. Directionally, this adjustment is made normal to the profile measurement dimension.

摘要： A crude curved log with an essentially circular cross-section is before a first machining cycle in a working machine fixed in a rotary condition where the longitudinal sectional plane comprising the maximum curvature is horizontal, and is then measured and processed along curved paths determined in a computer unit on the basis of the measured curvature. Thereafter the central block, thus obtained is processed, in a second cycle along paths having the same curvature as the first cycle by utilizing the same command signals as in the first cycle are used, possibly with a correction for changed lateral position of the block.

摘要： A method and apparatus for trimming boards, wherein a first stage, a first mechanism initially fixes and cuts two positioning short end cuts for each board. These positioning short end cuts are then used for advancing the board into the corresponding cutting plane of a second mechanism for trimming the board. As a result, it is possible to take into account the natural growth of a tree (all trees become thinner towards the top) and produce the minimum of trimmed waste. Because the natural growth of a tree to a conical shape, the positioning end cuts of a board will frequently define two non-parallel cutting lines for the edges of the board. The trimming in the second mechanism can be performed by different tools, e.g. by saws or one or more milling cutters. If a milling cutter is used, the boards can also be positioned in such a way that the sloping edges of the board resulting from the substantially circular cross-section of a tree can be taken into account. i.e., an inclined trimming takes place, taking into account the natural shape of the board so that there is a minimum of waste in this trimming dimension. If two cutters are used, the two stepped milling tools can be arranged in such a way that the largest diameter portion of one cutter is associated with the smallest diameter portion of the other cutter. In this case, the cut profiles on the edges of two adjoining boards that are cut by the two cutters match one another and fit together, so that without further manipulation, gluing in a joint gluing installation is possible. The boards are transported through the trimming mechanism in the desired manner by a pair of stops, a slide and a pair of ejectors. These members function in such a way that the desired cutting quality and shape are obtained for the board, while producing minimum waste.
摘要翻译： 一种用于修整板的方法和装置，其中第一阶段，第一机构最初固定和切割每个板的两个定位短端切口。 然后，这些定位短端切割用于将板推进到用于修整板的第二机构的相应切割平面中。 因此，有可能考虑到一棵树的自然生长（所有的树木都朝着顶部变薄），并产生最少的修剪废物。 由于树的自然生长为圆锥形，板的定位端切口将经常为板的边缘定义两条不平行的切割线。 第二机制中的修剪可以由不同的工具执行，例如， 通过锯或一个或多个铣刀。 如果使用铣刀，则也可以将这些板定位成使得可以考虑由树的基本圆形横截面产生的板的倾斜边缘。 即，考虑到板的自然形状，发生倾斜的修整，使得在该修整尺寸中存在最少的浪费。 如果使用两个切割器，则两个阶梯式铣刀可以以这样的方式布置，使得一个切割器的最大直径部分与另一个切割器的最小直径部分相关联。 在这种情况下，由两个切割器切割的两个相邻板的边缘上的切割轮廓彼此匹配并且配合在一起，使得在不进一步操纵的情况下，可以在接合胶合安装中进行胶合。 板通过一对止动件，滑动件和一对喷射器以期望的方式输送通过修剪机构。 这些构件的作用是使板材获得所需的切割质量和形状，同时产生最少的废物。

摘要： An apparatus for aligning lumber, especially blocks from which the first pair of cants is removed, comprising a conveyor for transferring the blocks in longitudinal direction, a measuring station and a microprocessor or equivalent. Before feeding the blocks into a saw mill, they have to be aligned correctly in order to ascertain a maximum amount of wood products. In conventional apparatuses for aligning blocks, the alignment is performed on the unsawed surfaces of the block. In practice this leads to errors. In the present invention the errors can be eliminated by arranging the aligning members to comprise one or several short conveyors located in connection to the conveyor. The short conveyor can be shifted transversally both below and above the level of the conveyor, and it can be given a horizontal adjusting movement impulse according to the adjusting values received from the calculating unit.

摘要： Log processing apparatus comprises a cutting machine that defines a substantially vertical cutting plane, feed mechanism that feeds a log through the cutting machine in substantially lengthwise horizontal motion parallel to the cutting plane, a measuring station spaced horizontally and vertically from the cutting machine, and transfer mechanism by which a log is carried in horizontal translatory motion from the measuring station to the feed mechanism. At the measuring station, or before the log reaches that station, it is established in an optimum rotational orientation which is thereafter maintained through transfer of support of the log to a set of jaws on the feed mechanism. At the measuring station a relationship is ascertained between a calculated plane that extends lengthwise in the log and a reference plane defined at the measuring station that has a fixed relationship to the cutting plane. The transfer mechanism comprises supporting elements by which a log is confined against all motion except such translatory motion as is imparted to it by the transfer mechanism. The feed mechanism comprises two pairs of jaws, each pair arranged to clampingly grip a log without causing any shifting of it but also arranged for controlled lateral shifting in unison when gripping a log. Either the transfer mechanism or the feed mechanism translatingly elevates a log to the level for cutting, and after the feed mechanism jaws grip the log they shift it laterally to establish it with said calculated plane in a desired relationship to the cutting plane.

摘要： A log sawing apparatus is described for enabling a single person to control the sawing operation at a single log sawing station. The apparatus includes means for prealigning the log with respect to a projected grid in a first plane. After being prealigned, the log is transferred to the log sawing station where the log is held stationary. A saw carriage with a main saw thereon moves past the log sawing station to cut the log lengthwise. The log is held stationary by a log holding means that may be moved laterally to progressively feed the log laterally with the sawing plane. Log rotating means is provided at the log sawing station to rotate the log 90.degree. or 180.degree. to progressively present various log sides to the sawing plane. Additionally, a second alignment means is provided to align the log with respect to a second grid pattern to align the log in a second plane normal to the first plane.
