Abstract

Abstract A method of drying a veneer sheet is provided. The method comprises the steps of tenderizing, compressing, and drying a veneer sheet. The compressing and drying steps are performed at the same time. The tenderizing step is preferably be performed before the above two steps but may be done thereafter or at the same time. An apparatus for performing the method is also disclosed. The apparatus comprises tenderizing means, deceleration transfer means, and heating means. The deceleration and the heating means are combined into one section. A plurality of rollers are used as deceleration transfer means.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 83 words
An apparatus for drying a veneer sheet comprising: means for feeding a veneer in a predetermined direction having a normal speed transfer section and a deceleration transfer section provided on a downstream side of said normal speed transfer section; a tenderizing device for forming numerous small splits on the veneer sheet and located in at least one of said normal speed transfer section and said deceleration transfer section; and heating means provided in said deceleration transfer section for drying the veneer sheet therewithin.
Claim 2
Independent Claim 83 words
An apparatus for drying a veneer sheet comprising: means for feeding a veneer in a predetermined direction having a normal speed transfer section and a deceleration transfer section provided on a downstream side of said normal speed transfer section; a tenderizing device for forming numerous small splits on the veneer sheet and located in at least one of said normal speed transfer section and said deceleration transfer section; and heating means provided in said deceleration transfer section for drying the veneer sheet therewithin.
Claim 3
Independent Claim 145 words
An apparatus for drying a veneer sheet comprising: a plurality of rollers arranged in two rows staggered such that said rollers have respective axes parallelly extending in corners of a zigzag path and any two adjacent rollers define veneer passages between peripheries thereof, said rollers being driven to feed veneers in a predetermined direction; plural sets of elongate elements passed over said rollers in sequence along said zigzag path, each set holding a veneer sheet therebetween, said rollers having on peripheral surfaces thereof annular recesses adapted to fully receive roll side elements in said sets, said rollers being heated; selected rollers being driven at successively decreasing speeds toward said predetermined direction to form a deceleration section; and a tenderizing device for forming numerous small splits in veneer sheet and located in an upstream portion inclusive of said deceleration section with respect to said predetermined direction.
Claim 4
Independent Claim 145 words
An apparatus for drying a veneer sheet comprising: a plurality of rollers arranged in two rows staggered such that said rollers have respective axes parallelly extending in corners of a zigzag path and any two adjacent rollers define veneer passages between peripheries thereof, said rollers being driven to feed veneers in a predetermined direction; plural sets of elongate elements passed over said rollers in sequence along said zigzag path, each set holding a veneer sheet therebetween, said rollers having on peripheral surfaces thereof annular recesses adapted to fully receive roll side elements in said sets, said rollers being heated; selected rollers being driven at successively decreasing speeds toward said predetermined direction to form a deceleration section; and a tenderizing device for forming numerous small splits in veneer sheet and located in an upstream portion inclusive of said deceleration section with respect to said predetermined direction.
Claim 5
Dependent Claim 19 words
An apparatus as claimed in claim 2, wherein said elongated elements includes resilient elongated elements such as coil springs.
Claim 6
Dependent Claim 21 words
An apparatus as claimed in claim 2 or 3, wherein said speed-reducing mechanisms are operable at a variable speed reduction ratio.
