Abstract: 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.

Abstract: An apparatus for laterally separating a group of elongated magnetic elements, for example steel bars which are moving longitudinally along a conveyor. A rotatable fanning roll extends transversally across the path of the bars. The fanning roll has a magnet associated therewith. The magnet attracts the bars towards the fanning roll while simultaneously creating repulsion forces tending to laterally separate the bars. A deflecting roll located in advance of the fanning roll is employed to deflect the bars out of their normal path of travel in relation to the surface of the fanning roll to thereby produce a momentary separation between the front ends of the bars and the fanning roll. During this momentary separation, the magnetically induced repulsion forces are not impeded by frictional resistance between the bars and the surface of the fanning roll, and this in turn improves the resulting lateral bar separation.

Abstract: Apparatus is disclosed for feeding rectangular metal sheets from a supply to a cupping press in which can body blanks are cut and drawn from the metal sheets. The apparatus includes a table providing a flat conveying surface, and three sheet feeding mechanisms are provided at locations along the table between the opposite ends thereof. A sheet to be transferred is deposited on one end of the table and is transferred therefrom to a second position by an endless chain and feed finger arrangement. At the second position, the trailing edge of the sheet is engaged by a reciprocating feed finger arrangement to advance the sheet one step to a third position on the table in which the sheet is accurately spaced longitudinally relative to a reference point in the press.

Abstract: A plurality of rows of vertically spaced discs are located on opposite sides of the path of movement of a shake blank as it is pushed along a cutting plane into the path of a bandsaw blade. The discs on each side of the cutting plane have respective radii either uniformly progressively increasing for a portion of their perimeters or uniformly progressively decreasing for a portion of their perimeters so that as the discs rotate they engage opposite side faces of the blank, advancing the blank in the cutting path and simultaneously skew the rearward end of the shake laterally of the cutting plane so that the shake blank is cut along a diagonal. The framework supporting all of the discs can be moved to simultaneously shift all discs laterally to accommodate cutting characteristics of a particular saw blade. Initial positioning of the forward end and final positioning of the rearward end of the blank for overly thick blanks is obtained by cam surfaces on the two rows of discs closest upstream of the blade.

Abstract: A log feed mechanism that will longitudinally move successive logs toward the cutting and/or chipping mechanisms of a sawmill while holding the successive logs along a prescribed path of movement such that the successive logs may be efficiently sawed into standard size lumber. The feed mechanism includes a roller device by which the successive logs may be rotated about their longitudinal center axes in order to determine the most desirable position for the log to be in when cut into lumber. The successive logs are fed onto a first conveyor assembly that performs the functions of centering the successive logs and moving the logs in a forward direction while maintaining the centered condition. Press rolls are provided over the first conveyor on either side of a rosser. The rosser operates to remove knots and enlarged butts of successive logs to provide a relatively smooth surface for gripping by a downstream second conveyor.

Abstract: Printed circuit boards are moved in a conveyor with the underside of flat boards spaced a prescribed distance above the top surface of a rotating cutting disk. In order to protect the circuit patterns on the underside of the board and the board itself, a V-shaped wheel is loosely rotatably supported on a shaft with the wheel being in front of and orthogonal to the cutting disk. The height of the wheel is adjusted such that the uppermost point on the circumference thereof is in the line of travel of the boards. Movement of a board that is bowed downward in the direction of the disk causes the wheel to roll on the underside of the board and to raise the board above the top of the cutting disk. In this manner, the underside of warped circuit boards is maintained at least a prescribed distance above the top surface of the cutting disk as the board moves over the leading - cutting edge of the latter and component leads are trimmed thereby.

Abstract: Box capacitors are loaded onto an in-line track feeder with the capacitor leads extending downward between a pair of tracks. Vibration of the tracks moves the capacitors thereon so that the capacitor leads pass between the meshing teeth of a drive gear and an idler gear that is caused to turn by the former. The tracks are spaced from the gears to prevent damping of vibrations of the former. The leading edges of the teeth on the gears have a radius thereon for providing smooth feeding action of the capacitor leads between the gear teeth. The drive gear also has a chamfer on the top edges of the teeth thereof to reduce the possibility of jamming on components with bent leads. A disk is attached to the underside of the idler gear for cutting the component leads to a prescribed length as they pass between the disk and the drive gear. The ends of the teeth on the idler gear are truncated such that a cut lead is compressed into a valley between teeth on the drive gear to thereby straighten these leads.
