PURPOSE:To enable a stacker or cross-conveyer to be certainly supplied with a corrugated sheet not subjected to undesirable bending deformation, by dividing a conveyer into its main portion and front edge portion that are made independently rotatable. CONSTITUTION:In order to interrupt supply of corrugated sheets to stacker etc. the rotational speed of a main conveyer 3 is increased to reduce overlap of the sheets on the conveyer 3, then a lifting bar 6 is raised together with reduction in the speed of the conveyer 3 and further the speed of a sub-conveyer 4 is decreased. Then, the sheet Pa is lifted by the bar 6, thereby frictional force is generated between the sheet and the bar 6 and feed of sheet stops due to eliminated feeding effect of the sub-conveyer 4. On the other hand, a sheet Pb on the conveyer 4 continues its travel to be fed onto a stacker. During the above process, new sheets are placed on the conveyer 3 to increase the number of sheet thereon, and the pitch between adjacent sheets if decreased by slowing down the speed of conveyer 3. Thus every sheet can be certainly feed onto the stacker without any change of dense overlap only on the bar 6, meandering route of travel and bending deformation. |
