ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a device. A plurality of partially overlapping paddles are pivotably fastened on an endless holder for guiding printed products.
DESCRIPTION OF THE PRIOR ART
A device for delivering printed products from a folding apparatus of a web-fed rotary printing press is known from CH 682 230 A5. This device consists of an endless chain conveyor, on each of whose links a paddle and a clamping element are each arranged. One printed product is respectively received between the paddle and the clamping element and is deposited at another processing station.
The object of the present invention is based on providing a device which delivers printed products in an imbricated or overlapping manner on a delivery belt.
In accordance with the present invention, this object is attained by using a printed product guiding device which utilizes a plurality of pivotable paddles attached to an endless holder. The paddles or blades are partially overlapping and define an arrangement of printed product receiving pockets.
The advantages which can be achieved by means of the present invention reside, in particular, in that, assuming the same production speed, each printed product which has fallen into a paddle pocket can have a dwell time which is several times longer than in a pocket of, for example, a known prior art paddle wheel. Even at high production speeds, the printed products can be steadied and aligned after having been received in the paddle pockets of the present invention.
Because of the pivoting movement of the paddles, the printed products slide more slowly, and therefore are placed in better alignment, on the delivery belt. This is advantageous in particular when using non-curved paddles, which can be produced in a simple manner.
With a further embodiment of the invention, the dwell time of the printed products in the paddle pockets can be extended by means of the arrangement of a delivery path. The printed products can be pushed out of the paddle pocket more gently by means of this arrangement and an improved delivery quality can therefore be achieved.
