Abstract:
A veneer roll unwinding apparatus at least comprising:a take-up reel on which a veneer sheet is wound to form a veneer roll and which is rotatably supported with bearings at both ends thereof by reel receivers at an unwinding position; base end pulleys fixedly mounted on a support shaft disposed almost in parallel to a shaft direction of the take-up reel below the unwinding position; drive guide bands that respectively extend over the base end pulleys and distal end pulleys disposed at a distal end thereof, whose distal end is swingable with the support shaft as a fulcrum and which can be pressed to part of a circumferential surface of the veneer roll; relay pulleys whose diameter is larger than that of the base end pulleys, which are mounted on the support shaft in a rotatable manner adjacent to the base end pulley and onto which a veneer sheet in transportation on the drive guide bands is transferred during folding-back; and a fold-back member that folds back a veneer sheet in a state where the veneer sheet is externally pressed from both sides thereof when the veneer sheet is folded back on the relay pulleys while the veneer sheet is kept in sliding contact with an outer circumferential surface on the fold-back sides of the relay pulleys.
