Claims
- 1. A method for producing a veneer web by joining individual veneer strips of limited length and width, said strips being cut from a raw veneer sheet in dependence on fault areas and quality variations thereof, comprising the steps of:
- (a) dividing the raw veneer substantially parallel to the fiber direction into strips of equal width independently of the dimensions of the finished veneer web,
- (b) trimming the non-usable longitudinal sections of strips having partially unacceptable faults along their longitudinal extent for obtaining equal width strip sections of effectively usable length,
- (c) eliminating strips having no effectively usable sections as well as the non-usable sections trimmed off the usable strip sections,
- (d) joining the usable strip sections and any usable full length strips in their longitudinal direction for obtaining an endless strip, and dividing the same into strip lengths all of equal width, and
- (e) joining the thus obtained strips, all of equal width, transversely to their longitudinal direction for obtaining a veneer web.
- 2. A method according to claim 1, characterized in that the usable strips and the usable strip sections are combined to form separate groups of different quality.
- 3. A method according to claim 2, characterized in that the width of all strips and the minimum length of the faultless strip sections are selected in dependency of the typical fault characteristic of the specific type of wood.
- 4. A method according to one of claims 1 to 3, characterized in that veneer strips of equal width and varying length that have not been obtained from a homogeneous raw wood block are joined to form veneer strips of equal length which are then joined to form a veneer web of a desired width.
- 5. A method according to one of claims 1 to 3, characterized in that full-length usable veneer strips obtained from a raw wood block of sufficient length are combined with strips of equal length formed of longitudinally joined strip sections to form a veneer web of a desired width.
- 6. A method according to claim 1 including the step of drying said raw veneer before said raw veneer is divided substantially parallel to the fiber direction.
