Abstract
A specific number of printed products is arranged on a supporting belt in a compacted imbricated formation. The printed product arranged at the leading end of the imbricated formation, as seen in the conveying direction, rests with its bottom end against a stop element. The printed product arranged at the other end bears, with its lower flat side, on the supporting belt. By virtue of the upending element being pivoted from a horizontal to an upright position, the imbricated formation is formed into a horizontal stack which is transferred to the removal conveyor by means of the stack transporter.

A process for stacking sheet-like products comprising the steps of arranging the products on a support one behind the other in a formation direction such that they overlap one another in an imbricated manner, wherein one of said products bears on a bottom edge of another of said products to cover the bottom edge thereof;
- orienting the imbricated products upon the support and transporting said products so that said bottom edges of said products extend across said support transverse to the formation direction;
- upending said products onto their bottom edge, wherein a predetermined number of products are arranged on the support in an imbricated formation in which a product arranged at one end of the formation lies with a flat side on the support and, in order to form a horizontal stack, the product arranged at the other end of the formation is brought to rest with its bottom edge oriented towards the support, against a stop, and the product lying with its flat side on the support is placed onto its bottom edge and is pushed in a direction towards the product resting against the stop.
An apparatus for stacking sheet-like products, comprising a support, a feed device for feeding products to the support such that the products are arranged on the support one behind the other in the longitudinal direction of said support and such that they overlap one another in an imbricated formation wherein a product bearing on an adjacent product covers a bottom edge of said adjacent product which is oriented towards the support and which is positioned so as to extend transverse to the longitudinal direction, said apparatus having means for upending the products onto each of said products' bottom edge, wherein the feed device feeds a predetermined number of products to the support wherein one of said products arranged at one end of the imbricated formation comes to lie with a flat side on the support, said apparatus further comprising a stop for acting on the bottom edge of a product arranged at the other end of the formation, said stop is configured to project beyond the support, said apparatus further comprising an upending element arranged in an initial position, beneath the product, lying with a flat side on the support, said upending element adapted to be moved into an upending position to upend said products onto their bottom edge, said upending element being adapted to be moved in the longitudinal direction of the support towards the stop.
