A woodworking machinery jig and fixture system includes a track which is or may be attached to a fence, a convex-concave curved flip stop and a base which mounts the stop to the track. The stop has a projecting portion which penetrates the plane of the fence so the stop isn't lifted by the point of a mitered board. The stop also has a lower convex surface which faces the work support surface and curves up at both ends. The top leg of the stop is concave toward the fence to allow clearance for a zero-clearance board and make the stop adaptable to different track and fence configurations. The base has opposite sides of different widths bordered by steps on one side and a ramp on the other side so the base can be used in a large range of T-track slot widths. The arm mounting hole of the base is offset from the base mounting so as to provide an offset to accommodate a ¾″ zero clearance board by turning the base a half turn relative to the slot. A two slot track is provided in which one of the slots can mount a sliding measurement tape or a base, and the other slot can also mount a base. In another track, a sidewall flange is provided which can be filed to accurately fit into a miter gauge slot of a cutting tool table.

The present invention provides systems and methods for end squaring and/or dividing elongated materials by determining an actual orientation of the elongated material, or an actual position of an associated pair of positioning mechanisms that are contactable with the elongated material, and changing the actual orientation to correspond with a desired orientation through independent movement of the positioning mechanisms prior to or during the end squaring and/or dividing operation.

A material handling system includes an array of independently controlled positioning devices, a positioning table which support and manipulate workpiece attributes such as position, orientation, velocity and/or acceleration of workpieces on the table. The positioning devices are arrayed such that no single positioning device supports more than one workpiece at a time, thereby allowing for simultaneous and independent control of each workpiece.

The present invention discloses a log sawing system comprising multiple cutting blades. The multiple cutting blades are positioned to cut laterally or perpendicular to the centerline of the log which is to be cut. The logs are transported into cutting position using some type of log positioner. The multiple cutting blades are rotatably mounted on an arm which is pivotally mounted on a shaft in groups, being driven by an electrical or like motor, all of which are mounted onto a platform positioned adjacent to the log to be cut. Hydraulic lifters are used to partially rotate the saw blades into the cutting position adjacent the log. Means utilizing a computer and lasers are provided to develop a log cutting solution to best utilize the logs.

The log positioning and conveying apparatus is used for conveying a log from an upstream end to a downstream end, and for positioning a log according to a predetermined downstream position. The apparatus comprises an open frame and a number of powered conveying rollers arranged therein in a row. These rollers, in addition to being rotatable, are displaceable in two directions relative to the open frame, namely, in a vertical direction for correcting the position of the log vertically relative to the open frame, and in a horizontal direction transversal to the longitudinal axis of the conveying apparatus, for correcting the position of the log transversely relative to the longitudinal axis.
