Abstract
Abstract An apparatus for dividing an imbricated stream of printed products into individual mutually separated sections, comprising a separator device which, in the conveying direction of a conveyor device, can be moved with a speed which is smaller than the conveying speed of such conveyor device. The separator device is equipped with a clamping device which selectively retains, for a certain time, a printed product and which can be forwardly moved at the speed of motion of the separator device. Owing to the lower speed of movement of the fixedly-retained printed product, in relation to the conveying speed of the conveyor device, there is formed a gap with respect to the leading printed product of the preceding section and which printed product moves forwardly at the full conveying speed. By means of this gap the successive sections can be separated from one another. The printed product which is fixedly retained by the clamping device serves as conveyor element for the successive or trailing printed products which come into contact therewith in an imbricated product stream.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
241 words
An apparatus for dividing a continuous stream, especially an imbricated product stream, of flat products, preferably printed products, into individual sections, comprising: A first conveyor device for feeding the products, said first conveyor device having a predetermined conveying direction; a second conveyor device arranged after the first conveyor device; said second conveyor device and said first conveyor device coacting with one another so as to define a region of transfer for the products from the first conveyor device to the second conveyor device; said second conveyor device, at least at the transfer region, being arranged below said first conveyor device; said second conveyor device, at least at the transfer region, having a conveying direction opposite to the conveying direction of the first conveyor device; a clamping device for selectively and temporarily fixedly holding at least one product; means for moving the clamping device in the conveying direction of the second conveyor device between a starting position and an end position at a speed which is less than the conveying speed of the second conveyor device; and means for activating said clamping device for selectively and temporarily fixedly holding at least one product moving in the conveying direction of the second conveyor device during the movement of the clamping device thereby dividing the continuous stream into individual sections, and for subsequently deactivating said clamping device for allowing said at least one held product to be again conveyed by said second conveyor device.
