Abstract

A device for deflecting a product stream consisting, in particular, of folded sheet products, from a first to at least one following longitudinal conveying device which are laterally displaced apart is provided. The distance between the first and second longitudinal conveying device is bridged by a further longitudinal conveying device which is inclined to an extent corresponding to the lateral displacement of the first and second longitudinal conveying device. The further longitudinal conveying device preferably includes two parallel, uniformly-driven conveying elements positioned adjacent to one another.

Claims

1. In a device for deflecting a product stream of folded sheet products from a first to at least a second longitudinal conveyor belt, said belts being laterally displaced with respect to one another, the improvement comprising:

a supplemental longitudinal conveying means which bridges the distance between the first and the second longitudinal conveyor belts and which is inclined to an extent corresponding to the lateral displacement of said first and second longitudinal conveyor belts, said longitudinal conveying means comprising two parallel, synchronously-driven conveyor belts positioned adjacent to one another which are each pivotably mounted about a pivot axis approximately running normally to the plane of conveyance and which are coupled with an adjusting device for adjusting their pivotable position, said adjusting device having an adjusting arm which is pivotably coupled with each of said parallel, adjacent conveyor belts at respective pivot points so that the distance between said pivot points of said adjusting arm is the same as the distance between the pivot axes, said arm being coupled with an adjusting spindle supported by an outer machine casing by means of a pin-slot connection.

2. The deflecting device according to claim 1, wherein said adjacent conveying elements are drive-coupled with each other by means of at least one universal shaft and are drive-coupled with the preceding and following first and second longitudinal conveying means by means of at least one universal shaft.

3. The deflecting device according to claim 2, wherein at least the universal shaft coupled with the drive for the preceding and following longitudinal first and second conveying means is designed as a telescopic shaft.

4. The deflecting device according to claim 2, wherein said adjacent conveying elements are each provided on a flank thereof with a gear-reducer connected to the universal shaft drive-coupling said elements with one another.
