Abstract: <P>PROBLEM TO BE SOLVED: To provide a drainboard inverting machine removing while inverting a material to be dried spread in a drainboard to another drainboard.  <P>SOLUTION: This drainboard inverting machine has inverting shelves which sequentially detect the positions of drainboard shelves along a frame of a dry stand so as to adjust the positions of the inverting shelves and the drainboard shelves. When the positions are adjusted, a drawing motor of the inverting shelf is driven and a pusher/puller is drawn out so as to catch a drainboard held in the drainboard shelf into the inverting shelf. The inverting shelf has two stages and an empty drainboard is previously held in the upper stage. When inverting the inverting shelf (180° rotation), the drainboard on which the material to be dried is put comes to the upper stage and the empty drainboard comes to the lower stage. As a result of this, the material falls down and moves to the empty drainboard by gravity, and at the same time, the front and the back thereof become reverse and the shape and the spread which are put become slightly different. The drainboard is inserted from the inverting shelf into an original drainboard shelf of the dry stand. The inverting shelf goes up and down repeating times of the number of stages of the drainboard shelves to complete inverting action of the drainboard.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
