A method and means of sheet imbricating and stacking of flexible sheets, such as signatures processed and delivered by a folder. A conveyor receives the sheets from the folder and delivers the sheets to another conveyor which moves at a speed less than the speed of the first conveyor. The slow moving conveyor deposits the sheets on a bed where the sheets are aligned in a stack. The first conveyor supports the sheets from underneath, and the first conveyor has a projection which holds the sheets upwardly relative to the remainder of the conveyor so that clearance is provided between the sheets and the remainder of the conveyor. Also, a brush is disposed adjacent the conveyor for brushing the trailing edge of the sheets upwardly. The projection and the brush are for the purpose of providing a space between the sheets and the remainder of the conveyor so that the oncoming sheets can be disposed underneath the sheets already on the first conveyor, and the sheets can therefore be taken from a spaced-apart relationship as they approach the first conveyor and then placed in an imbricated relationship on the first conveyor. The first conveyor then passes the imbricated related sheets to the second conveyor, and the sheets can then be stripped directly off the second conveyor and formed into a stack.
