Method of sawing and stacking board

Claim 2

Method of sawing and stacking board, with the board including first sheets and second sheets each having a longitudinal dimension and a transverse dimension, comprising the steps of moving one first sheet over a first saw table for cutting the sheets in the longitudinal direction and over a second saw table for cutting the sheets in a transverse direction and cutting the one first sheet at least for trimming the longitudinal edges thereof, placing the cut first sheet on the support surface of a stacking table for forming a support for the bottom of a stack, moving a number of second sheets in series over the first saw table and over the second saw table and cutting each of the second sheets at least in one of the longitudinal and transverse directions for forming a plurality of sub-divided second sheets from each one of the second sheets moved over the first and second saw tables, each of the sub-divided second sheets having a combined area size equal to or less than the size of the cut first sheet placed on the support surface, and stacking these smaller sub-divided second sheets, while maintaining their positions in relation to each other, on the cut first sheet lying on the stacking table, so that the cut first sheet thus forms a supporting surface for the sub-divided second sheets cut from said second sheets of board.

Claim 3

Method according to claim 1 for sawing and stacking board including supplying first sheets and second sheets where the second sheets are approximately the same size in the longitudinal and transverse directions as the first sheets, cutting one first sheet in at least one of the longitudinal and transverse directions for forming at least two part-first sheets, placing these part-first sheets, while maintaining their position in relation to each other, on the stacking table, cutting the second sheets in the longitudinal direction and in the transverse direction for forming the plurality of sub-divided second sheets from each of the second sheets so that at least some of the sub-divided second sheets are smaller than the part-first sheets located on the stacking table, stacking the subdivided second sheets in a number of stacks on the part-first sheets, while maintaining their positions in relation to each other, on the part-first sheets lying on the stacking table, so that each part-first sheet thus forms a support surface for at least one stack of smaller second sheets with each stack of the sub-divided second sheets being supported on only one of the part-first sheets whereby the stacks of subdivided second sheets do not overlay more than one of the part-first sheets.

Claim 4

Method according to claim 2, comprising conveying second sheets to the first saw table and carrying out the step of dividing the second sheets in the longitudinal direction by a number of laterally spaced circular saw blades on the first saw table, conveying the previously subdivided second sheets from the first saw table onto the second saw table, further carrying out the step of dividing the second sheets in the transverse direction by a number of laterally spaced circular saw blades on the second saw table, and removing the two directionally divided second sheets from the second saw table and stacking of two directionally divided second sheets thus produced, characterized in moving a number of saw blades at the first and second saw tables into a position inoperative for sawing while retaining at least one of the saw blades located intermediate the sides of the sheets to be cut in operative position at each saw table, conveying a first sheet to the first and the second saw tables and dividing it into at least four part-support sheets as it moves over the saw tables, placing these part-support sheets, while maintaining their positions in relation to each other, on the stacking table, moving at least some of the saw blades at each of the first and second tables located between the sides of the sheets to be cut from the inoperative to the operative position, the said step of conveying a plurality of second sheets in series to the first and second saw tables including the steps of dividing them into smaller sub-divided second sheets smaller than the part-first sheets, stacking said smaller second sheets, while maintaining their position in relation to each other, on the part-support sheets produced previously and located at the stacking table.

Claim 5

Method according to claim 1, comprising conveying a first sheet to the first saw table containing a first cross-cut saw cutting in the longitudinal direction of the sheets, conveying said support sheet to a second saw table containing a second cross-cut saw cutting in the transverse direction of the sheets, dividing said first sheet into at least two part-first sheets by sawing it by at least one of said first and second cross-cut saws, placing said part-first sheets on the stacking table while maintaining their positions in relation to each other, conveying a plurality of second sheets in series to said first and second saw tables, dividing said second sheets into at least three smaller sheets by sawing them by at least one of said first and second cross-cut saws, and stacking said smaller second sheets, while maintaining their positions in relation to each other, on said part-first sheets previously produced, with at least one of said part-first sheets completely supporting at least two stacks of smaller second sheets.

Claim 6

Method of sawing and stacking board, with the board including first sheets and second sheets each having a longitudinal dimension and a transverse dimension, comprising the steps of moving one first sheet over a first saw table for cutting the sheets in the longitudinal direction and over a second saw table for cutting the sheets in a transverse direction and cutting the one first sheet at least for trimming the longitudinal and transverse edges thereof, placing the cut first sheet on the support surface of a stacking table for forming a support for the bottom of a stack, moving a number of second sheets in series over the first saw table and over the second saw table and trimming the longitudinal and transverse edges of said second sheets and cutting each of the second sheets at least in one of the longitudinal and transverse directions for forming a plurality of sub-divided second sheets from each one of the second sheets moved over the first and second saw tables, each of the sub-divided second sheets having a combined area size equal to or less than the size of the cut first sheet placed on the support surface, and stacking these smaller sub-divided second sheets, while maintaining their positions in relation to each other, on the cut first sheet lying on the stacking table, so that the cut first sheet thus forms a supporting surface for the sub-divided second sheets cut from said second sheets of board.

Claim 7

Method of sawing and stacking board, with the board including first sheets and second sheets each having a longitudinal dimension and a transverse dimension, comprising the steps of moving one first sheet over a first saw table for cutting the sheets in the longitudinal direction and over a second saw table for cutting the sheets in a transverse direction and cutting the one first sheet at least for trimming the longitudinal and transverse edges thereof, placing the cut first sheet on the support surface of a stacking table for forming a support for the bottom of a stack, moving a number of second sheets in series over the first saw table and over the second saw table and trimming the longitudinal and transverse edges of said second sheets and cutting each of the second sheets at least in one of the longitudinal and transverse directions for forming a plurality of sub-divided second sheets from each one of the second sheets moved over the first and second saw tables, each of the sub-divided second sheets having a combined area size equal to or less than the size of the cut first sheet placed on the support surface, and stacking these smaller sub-divided second sheets, while maintaining their positions in relation to each other, on the cut first sheet lying on the stacking table, so that the cut first sheet thus forms a supporting surface for the sub-divided second sheets cut from said second sheets of board.
