Process for the buffer storage and conversion of flat products in stream formation
First Claim
1. A method for the buffer storage of flat products arriving in a stream at an apparatus including a plurality of roll modules each having a product roll comprising the steps ofdirecting products to the plurality of roll modules (41-45), the stream of products having inlet parameters (I, o1, t1, p) wherein I is representative of the relative delivery position of the products, o1 is representative of the orientation of the products, t1 is the timing frequency of the products and p is the phase of the products;
- concurrently removing a stream of products at least partly from a first one of the plurality of roll modules (41-45) through an outlet common to the roll modules, the removed products having outlet parameters (I=hd 2, o2, t2, p) wherein at least one of I2, o2 and t2 differs, respectively, from I, o1 and t1 ;
selectively storing products by temporarily holding products on a second roll as a storage unit for introducing buffer storage delay for a selected group of products held on the roll, andremoving the storage unit (10) with products thereon through at least one additional outlet (31-35).

Abstract
A buffer storage arrangement contains at least two roll modules (41-44) with interchangeable roll hubs or rolls. A common feed belt (11), the winding planes of the roll modules (41-44) and a common removal belt (12) are located in a vertical plane. The feed belt (11) passes linearly over the winding stations (41-44) and has a number of branching locations (51-54) corresponding at least to the number of winding stations (41-44). Each winding station (41-44) has a connection to the removal belt (12), which passes linearly beneath the winding stations. In order to be able to select the reciprocal arrangement of the products at the outlet, within the apparatus at least one device (7, 79) is provided for rewinding the rolls or for modifying the inlet parameters of the arrangement of the printed products. This permits unrestricted off-line buffer storage or the products and flexible conversion of their inlet parameters, with respect to their reciprocal positioning, orientation or timing frequency.
