Abstract
A folding machine and a folding method perform overlapped folding of sheets of paper, paperboard and the like. The folding machine has at least one first and one second folding station each having driven folding rolls, a transport device disposed between the first and second folding stations, a drive and a common control unit connected to the drives. The products are transported between the first and the second folding stations in an overlapping manner.
Claims6
A method for folding sheet elements in a folding machine having a folding station with at least one folding unit, the method comprising the following steps:
- supplying the sheet elements to the folding station in a transport direction with leading edges of the sheet elements in front and with an overlap;
- folding the sheet elements upward with a first folding length in the at least one folding unit;
- producing a fold transversely with respect to the transport direction to create a first folded product;
- defining a distance between the leading edge of a first folded sheet element and the leading edge of a following sheet element in each case to be greater than or equal to zero;
- and
- dimensioning the overlap to correspond at most to the first folding length.
A folding machine for folding sheet elements of paper or paperboard, the folding machine comprising:
- at least one first and at least one second folding station each having driven folding rolls;
- each of said folding stations having at least one drive;
- a transport device having a drive and being disposed between said at least one first and said at least one second folding station and configured to transport products in an overlapping manner between said at least one first and said at least one second folding station;
- and
- a control unit connected in common to said drives.
