Method and an apparatus for producing wood wool

Claim 3

The method claimed in claim 1 in which said steady motion is imparted to said surface in a direction extending transversely to the fibers of said block and in which said cutting edge extends transversely to said steady motion.

Claim 6

Apparatus for producing wood wool comprising a rotary substantially disk-shaped planing tool provided with at least one cutting edge, means for imparting rotation to said tool, holding means for holding a block of wood with the fibers of said block extending substantially parallel to the rotation direction of said tool and for presenting said block to one side of said rotary planing tool, feeding means for producing a relative feed motion between said holding means and said tool for causing the latter to slice successive sheets from said block, conveyor means including a conveyor disposed on the other side of said tool and having a supporting surface movable past said tool for receiving said sheets for deposition on said supporting surface in superimposed staggered relationship like fish scales, a wool cutting station, said conveying means extending from a point near said tool and to said station, and a wool cutting tool at said station mounted to perform a cutting motion substantially transversely to said sheets and substantially parallel to said fibers for simultaneously cutting wool from said superimposed sheets, and means cooperatively connected to said conveyor and to said planing tool for operating said conveyor At a speed so correlated to the rotary speed of said planing tool that the distance through which said conveyor travels during the period of slicing a sheet from said block is a small fraction of the average length of said sheet.

Claim 7

Apparatus for producing wood wool comprising a rotary substantially disk-shaped planing tool provided with at least one cutting edge, means for imparting rotation to said tool, holding means for holding a block of wood with the fibers of said block extending substantially parallel to the rotation direction of said tool and for presenting said block to one side of said rotary planing tool, feeding means for producing a relative feed motion between said holding means and said tool for causing the latter to slice successive sheets from said block, conveyor means including a conveyor disposed on the other side of said tool and having a supporting surface movable past said tool for receiving said sheets for deposition on said supporting surface in superimposed staggered relationship like fish scales, a wool cutting station, said conveying means extending from a point near said tool and to said station, and a wool cutting tool at said station mounted to perform a cutting motion substantially transversely to said sheets and substantially parallel to said fibers for simultaneously cutting wool from said superimposed sheets, and means cooperatively connected to said conveyor and to said planing tool for operating said conveyor At a speed so correlated to the rotary speed of said planing tool that the distance through which said conveyor travels during the period of slicing a sheet from said block is a small fraction of the average length of said sheet.

Claim 8

Apparatus as claimed in claim 4, in which the rotary axis of said planing tool is substantially vertical, said holding means being disposed above said tool and said conveyor means disposed below said tool.

Claim 9

Apparatus as claimed in claim 4, in which said wool cutting tool is a rotary tool.

Claim 10

Apparatus as claimed in claim 6 in which said rotary wool cutting tool has a plurality of circumferentially distributed cutting edges extending substantially parallel to the axis of said rotary wool cutting tool.

Claim 11

Apparatus as claimed in claim 4 in which said conveyor is an endless conveyor.

Claim 12

Apparatus as claimed in claim 7 further comprising a stationary frame supporting said conveying means and further supporting a counter cutting edge cooperating with said rotary wool cutting tool.

Claim 13

Apparatus as claimed in claim 4 further comprising means disposed above said conveyor for holding down the sheets deposited on said conveyor in staggered relationship.

Claim 14

Apparatus as claimed in claim 10 in which said means is formed by an endless belt movable in a path extending parallel to said conveyor.

Claim 15

Apparatus as claimed in claim 4 in which said wool cutting tool has a substantially vertical cutting direction.

Claim 16

Apparatus as claimed in claim 4 in which said supporting surface of said conveyor extends substantially within a plane slightly inclined relative to said rotary disk-shaped planing tool, the inclination being such that each sheet is disposed on said conveyor means in a position parallel to said disk-shaped planing tool.

Claim 17

Apparatus as claimed in claim 4 further comprising air nozzles provided on said planing tool so as to direct air jets in the sheet-depositing direction upon each sheet sliced off from said block.

Claim 18

Apparatus as claimed in claim 4 in which said holding means are so disposed relatively to said rotary planing tool that the fibers of wooden block extend substantially tangentially to the rotary motion of said tool.

Claim 19

The method according to claim 1, in which said steady motion is imparted to said surface in a direction extending parallel to the fibers of said block.
