ABSTRACT:
There is disclosed a device for orienting a sheet having a rectangular shape into a straight position. A sheet, which is fed forward in a position inclined in one way and then brought into contact engagement at one corner on the leading edge thereof with one of two working surfaces of the device is turned into a straight position by the feeding force acting on the sheet to move it forward and of the force of a working surface of the device acting on that corner to move it in a direction perpendicular to that of the feeding force and away from the other corner on the same leading edge of the sheet. The device includes feeding rollers for feeding the veneer sheet forward, and first and second driven sheet orienting belts or sets of vertical rollers, each disposed at the downstream end of the sheet feeding area and providing a working surface which moves either one of the corners on the leading edge of the sheet in the direction that causes the sheet to be turned into the desired straight position in conjunction with the feeding force.
