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.

Winding reel, veneer winding device, device for delivering tape to veneer roll, veneer roll unwinding device, and method of manufacturing plywood

Apparatus for distributing veneer sheets comprises a pair of vertically-movable upper and lower relay conveyors for receiving veneer sheets from a veneer conveyor and supplying the sheets to different treating sections of different heights of a veneer treating system, such as a veneer drying system. When receiving the sheet from the veneer conveyor, each relay conveyor is horizontally aligned with the veneer conveyor. When supplying the sheet to the treating section, each relay conveyor is in a position adjacent to the section. Each relay conveyor may receive a veneer sheet while the other conveyor is supplying the sheet to the treating section.
