Abstract:
1. A process for covering a flat-lying blank with a cover in the production of a book cover, the process comprising the steps of: providing a plurality of working stations configured for covering a flat-lying blank with a cover in the production of a book cover, the plurality of working stations including at least a joining station and a folding station; providing a transport element; setting an overall cycle time during which the plurality of working stations operate together to cover a predetermined number of flat-lying blanks with covers, each working station carrying out a number of procedural steps; assigning a sub-cycle time to each procedural step carried out at each working station, each sub-cycle time defining part of the overall cycle time; joining a flat-lying blank and a cover to one another at the joining station to form a joined blank and cover so that the cover has a free edge which projects beyond an outer edge of the blank; transporting the joined blank and cover from the joining station to the folding station with the transport element; folding the free edge of the cover around the outer edge of the blank at the folding station; determining the properties of a particular material utilized in said process at one of the working stations; selectively varying one of the sub-cycle times assigned to one of the procedural steps by an increment to accommodate the properties of the particular material determined during said step of determining, wherein said step of selectively varying comprises varying the speed at which the one procedural step is carried out; and maintaining the overall cycle time constant by adjusting another sub-cycle time assigned to another procedural step by an increment equal to the increment by which the one sub-cycle time is selectively varied.
