Take-up reel, veneer reeling apparatus, tape feeding unit for veneer roll, veneer roll unwinding apparatus and a production method for laminated wood
摘要:
A take-up reel has a diameter equal to or more than 85 times a thickness of a veneer sheet wound thereon and equal to or more than 300 mm so as to be of a curvature of the take-up reel to reduce cracking in parallel to fiber orientations that occurs in winding a veneer sheet after drying on a winding surface of the take-up reel. A veneer reeling apparatus comprises: a take-up reel disposed in a veneer sheet reeling position in a rotatable manner; a drive roller disposed on the lower surface of the take-up reel, transmitting a driving force with a variable speed: a veneer dryer disposed upstream from the veneer sheet reeling position; a conveyor provided between the terminal end of the veneer dryer and the drive roller in the veneer sheet reeling position; and a plurality of thread feeding mechanisms disposed at arbitrary spatial intervals along a length direction of the take-up reel for a veneer sheet, wherein a continuous dried veneer sheet or dried veneer sheets whose sizes are of a constant length or of a length at random are wound on the take-up reel to form a veneer roll with threads as guide by a frictional force of the drive roller. Further, pairs of two overlapping veneer sheets or sets of a pair of two overlapping veneer sheets and a single veneer sheet can be wound on the take-up reel in a composite form.
