Abstract
A laminated rail for a sawmill bed comprises an outer plate having a middle body portion, a top portion, and a bottom portion; and an inner plate secured to the outer plate, the inner plate having a middle body portion, a top portion, and a bottom portion. The middle body portion of each of the inner plate and the outer plate may have substantially the same cross sectional tacking configuration to allow the inner plate to be matingly received by the outer plate. A channel may be formed between the top portion of the inner plate and the top portion of the outer plate, the channel being shaped and dimensioned to receive and secure a track in a sandwich grip.
Claims19
A laminated rail for a sawmill bed, the laminated rail comprising:
- an outer plate having a middle body portion, a top portion, and a bottom portion;
- an inner plate secured to the outer plate, the inner plate having a middle body portion, a top portion, and a bottom portion;
- wherein at least the middle body portion of each of the inner plate and the outer plate have a cross sectional configuration having multiple obtuse angles along a vertical axis to form a vertically upright rail and the inner plate is matingly received by the outer plate.
A method of manufacturing a laminated rail for a sawmill bed, the method comprising:
- roll forming an outer plate having a middle body portion, a top portion, and a bottom portion with a cross sectional configuration with multiple obtuse angles along a vertical axis;
- roll forming an inner plate having a middle body portion, a top portion, and a bottom portion with a cross sectional configuration to allow the inner plate to be matingly received by the outer plate;
- and
- securing the outer plate to the inner plate to form the laminated rail.
