ABSTRACT OF THE DISCLOSURE A layboy mechanism for the continuous stacking and delivery of batches of sheet material received from a delivery mechanism. The mechanism continuously assembles sheets into a downwardly moving stack. A divider is down- wardly movable with the stack for dividing the stack as it is formed into batches containing a predetermined number of sheets. An auxiliary support moves between an operative support position and an inoperative position clear of the stack. The divider is operated to cause an opening between the lowermost batch and a batch above it to enable the auxiliary support to enter the stack at the opening. The lowermost batch is removed whilst the remainder of the stack above it is supported by the auxiliary support. The divider includes a number of divider elements and a divider element feeding and withdrawing device. This device operates to position a divider element on the top of a formed stack to define a batch and move downwards with it. The device then removes that batch when the batch below it is removed from the stack. The divider elements may be stored in a magazine from which they are fed by the feeding and withdrawing device. Typically, each divider element comprises two or more thin fingers carried on a support. The mechanism can collect sheets continuously; prior art mechanisms have generally required intermittent operation.
