Workpiece strip along a transverse direction of the workpiece is divided into sections, and at least one longitudinal split section of a second order, through which one of the sections along a

Split longitudinal direction of the workpiece. In conventional methods for splitting

plate-shaped workpieces, these are first by the Längsaufteilschnitte the first order in

Workpiece strip divided and the workpiece strip in turn by Queraufteilschnitte in sections. The individual cuts are finally by the

Split longitudinal sections of the second order further.

EP 2 422 944 describes a method for dividing a plate into at least one of the partial plates of one in a third method section subsequently or during the second method section

Rear transport device of the panel splitter to the or one of the sawing is transported back and sawed by this sawing means by means of at least a third section again, is described in [0022] the EP 2 422 944 that third cuts (in the longitudinal direction) not at the same time but with time offset to the First cuts (in the longitudinal direction) and second cuts (in the transverse direction) are performed. Object of the present invention is to provide a method for dividing preferably plate-shaped workpieces, with which the workpieces can be divided particularly efficiently.

This object is achieved in a method mentioned above in that the at least one Queraufteilschnitt possibly one of Queraufteilschnitte with the

Längsaufteilschnitt the second order, where appropriate, one of the Längsaufteilschnitte the second order in one

common cutting process is performed. This reduces the number of times to be performed

Cutting operations and the procedure can be on

The dividing means is preferably a circular saw blade arranged on a saw carriage sawing saw, wherein the circular saw blade by means of the saw carriage along the

Aufteillinie is movable. This allows the

Cutting operations are carried out particularly efficiently and cleanly. Preferably, in the

Workpiece dividing system to a system that is designed for the division of wood-based plate-shaped workpieces.

It is also advantageous if the second-order longitudinal cutting cut, which is carried out in the common cutting operation with the transverse cutting cut, separates a piece of waste from a product piece. In the just described Thus, a common cutting operation, a piece of waste is separated from a product piece, wherein the product piece can still be connected to other product pieces and / or one or more other waste piece (s). The

By contrast, waste can be disposed of directly after separation. For example, the piece of waste may be removed from a working area around the dividing line via a type of slide and optionally a fold-down part of a workpiece support table.

It is likewise advantageous if the second-order longitudinal dividing cut, which is carried out in the common cutting operation with the transverse dividing cut, separates a finished product piece, in particular a finished one

Product piece separates from a last piece of waste.

This results in the common cutting process, a finished product piece can be removed from the Werkstückaufteilanlage and stacked. In this case, a finished product piece means a product piece to which no waste pieces or other product pieces more adjacent, which would have to be further separated.

In a preferred variant of the invention

Method is during the Längsaufteilschnitt the second order, which is carried out in the common cutting process with the Queraufteilschnitt, the aufzusutilende workpiece strip or piece to be split on a workpiece stop the Werkstückaufteilanlage to determine the position of the splitting workpiece strip or the part with respect to the split line, where preferably the workpiece stop the
