An edger feeding apparatus and method of placing flitches in position to be fed into an edger with minimal spacing between successive flitches and with flitches oriented and the edger adjusted so as to yield a maximum value of lumber from each flitch. The edger feeding apparatus may include a scanning system for creating and storing a digital three-dimensional model of each flitch. The apparatus and method may also include a control computer and its use for determining the optimum position for feeding each flitch into the edger to produce the most valuable yield of lumber from the flitch.

A dual-spindle circular saw (1) for sawing wood (2) with two saw groups (3) is proposed, wherein each saw group (3) comprises a drive (7) having an armature (5) and a stator (6) for rotary driving of a saw spindle (9) which is mounted in a housing (8) and which is connected in a rotationally fixed manner to at least one saw tool (11) comprising at least one exchangeable circular saw blade (10), and wherein the center distance (A) of the saw spindles (9) is adjustable by means of an actuator. In order to create particularly advantageous design conditions, it is proposed that the armature (5) is arranged in a rotationally fixed manner on the saw spindle (9) and the stator (6) is arranged in a rotationally fixed manner in the housing (8) between a fixed bearing (13) and a floating bearing (14) of the saw spindle (9), wherein the saw tool (11) is floatingly mounted on the saw spindle (9).

A saw guide for a saw arbor guide assembly comprises a head, a body, and one or more passages. The head has one or more intake channels adapted to supply lubricant to the saw guide. The body is connected to the head, with the body located between adjacent ones of the saw blades. The body has first and second faces, with the body further having a plurality of lubricant openings located on one or both of the first and second faces for supplying the lubricant to the saw blades. The passages extend through the head and the body and connect each of the intake channels with the lubricant openings, with the passages configured to carry lubricant from the one or more intake channels to the lubricant openings. For each of the lubricant openings, a flow control valve is located in the passage proximate to the lubricant opening to control a flow of lubricant through the lubricant opening. The flow control valves are configured to differentially control the flow of lubricant to the lubricant openings.

An automated cutting for scenic flats construction system and method for cutting of wide dadoes accurately spaced along sets of multiple boards to be used as studs or stiles for scenic flats, cleanly and accurately across the boards in one pass for each wide dado cut. A controller controls the automatic operation. A main unit with a support stand and a main-unit shell provides a sled unit extending and retracting along linear-bearing tracks by operation of sled actuators controlled by the controller. The sled unit provides a wide one-pass dado blade assembly capable of cutting a wide dado across multiple boards in one pass as the sled unit is moved along the linear-bearing tracks by the sled actuators under the control of the controller. After initial positioning of the set of uncut boards on an infeed table and against a positioning stop, the set of boards is held in place by hold-down clamps, the wide dado cut is made in one pass of the sled unit with the wide one-pass dado blade assembly, the hold-down clamps are released, the set of boards is moved through the main unit and toward a receiving table by a pre-set distance by a driving dog on a drive chain, the hold-down clamps are activated, and another wide dado cut is made in one pass, all under the control of the controller, repeating until all dado cuts are made to the set of boards.
