Abstract
The invention relates to a method and an apparatus for conveying a stream of printed products. The printed products are first conveyed along a first conveyor loop in a position in which they are oriented essentially tangentially to the conveying direction, and are transferred to a second conveyor loop. To facilitate the transfer, the printed products are brought into a transfer position, in which at least one region of each printed product is oriented at an angle to the tangential orientation.
Claims11
A method of conveying a stream of printed products comprising the steps of:
- orienting products one behind the other individually in a first section of an endlessly-circulating, first conveyor loop, said individual products being aligned essentially tangentially to a conveying direction of the first endlessly-circulating conveyor loop;
- transferring the individual products to a second endlessly-circulating conveyor loop wherein at least one region of each printed product is oriented at an angle to the tangential orientation in a second section of the first conveyor loop adjoining the first section during the transferring step;
- conveying the individual printed products along the second conveyor loop with a second conveying device that includes a plurality of grippers that are disposed one behind the other and can be switched between an open position and a closed position and, in the transferring step, the grippers pass a transfer region through which regions of the printed products oriented at an angle to the tangential orientation pass over the second section of the first conveyor loop, and at least a few of the grippers are in the open position when they reach the transfer region in order to take up the printed products, and are switched into the closed position as they pass the transfer region in order to convey the printed products along the second conveyor;
- and
- controlling the second conveyor device as a function of the conveying speed for the individual printed products and the spacing between regions of the printed products that are oriented at an angle to the tangential orientation in the transfer region, such that each printed product is taken up by a gripper and conveyed along the second conveyor loop.
A method of conveying a stream of printed products comprising the steps of:
- orienting products one behind the other individually in a first section of an endlessly-circulating, first conveyor loop, said individual products being aligned essentially tangentially to a conveying direction of the first endlessly-circulating conveyor loop;
- and
- transferring the individual products to a second endlessly-circulating conveyor loop wherein at least one region of each printed product is oriented at an angle to the tangential orientation in a second section of the first conveyor loop adjoining the first section during the transferring step.
An apparatus for conveying a stream of printed products comprising a first conveying device that can be operated to convey the printed products, in a position in which they are oriented individually and essentially tangentially to the conveying direction, along a first section of an endlessly-circulating, first conveyor loop, and a second conveying device that can be operated to convey the printed products conveyed along the first convey or loop, wherein an orienting device, is can be placed against one of the individual printed products, the printed products are brought into a transfer position, in which at least one region of the printed products is oriented at an angle to the tangential orientation so that the printed products can be transferred to the second conveying device in a second section of the first conveyor loop that adjoins the first section.
