A method for separating sheet-shaped objects into strip-shaped or slab-shaped object sub-units, comprising the following steps: - providing and conveying the sheet-shaped objects, wherein each sheet-shaped object has weakening regions which run perpendicularly to the conveying direction of the sheet-shaped objects; - successively separating individual strip-shaped or slab-shaped object sub-units one after another from the provided sheet-shaped objects, wherein separating takes place on the weakening regions of the sheet-shaped objects by means of a conveying and separating device, in that the conveying and separating device picks up the sheet-shaped objects in each case individually, successively one after another, and holds them in a force-fitting and form-fitting manner and conveys them in the plane of their extent, and in that, in the conveying direction of the sheet-shaped object, the in each case frontmost part of the sheet-shaped object is severed from the sheet-shaped object at the in each case frontmost weakening region and wherein the strip-shaped or slab-shaped object sub-unit respectively formed thereby is deposited; and - onward conveying of the individual, formed strip-shaped or slab-shaped object sub-units; characterized in that the step of separating by means of the conveying and separating device comprises the following further steps: - picking up, holding and conveying the sheet-shaped object by means of the suction effect of suction elements (30, 32) which are arranged on a conveying means which revolves in a belt-like manner, wherein the suction effect of the suction elements (30, 32) is activatable and deactivatable, and wherein the suction elements (30, 32) release the object (P, S) when the suction effect is deactivated; - holding the sheet-shaped object by way of the suction elements (30, 32) in such a manner that in each case at least one suction element (30, 32) engages with the sheet-shaped object between in each case two adjacent weakening regions; - severing in each case the frontmost part, in the conveying direction of the sheet-shaped object, which forms the strip-shaped or slab-shaped object sub-unit from the sheet-shaped object in that, on account of the revolving motion of the conveying means, a suction element (30, 32) which is assigned to said part is pivoted out of the conveying plane of the sheet-shaped object, on account of which said part of the sheet-shaped object, ahead of the in each case frontmost weakening region, is moved out of the conveying plane; and - depositing the formed strip-shaped or slab-shaped object sub-unit in that the suction effect of the suction element (30, 32) which is assigned to the severed object sub-unit is deactivated. - providing and conveying the sheet-shaped objects, wherein each sheet-shaped object has weakening regions which run perpendicularly to the conveying direction of the sheet-shaped objects; - successively separating individual strip-shaped or slab-shaped object sub-units one after another from the provided sheet-shaped objects, wherein separating takes place on the weakening regions of the sheet-shaped objects by means of a conveying and separating device, in that the conveying and separating device picks up the sheet-shaped objects in each case individually, successively one after another, and holds them in a force-fitting and form-fitting manner and conveys them in the plane of their extent, and in that, in the conveying direction of the sheet-shaped object, the in each case frontmost part of the sheet-shaped object is severed from the sheet-shaped object at the in each case frontmost weakening region and wherein the strip-shaped or slab-shaped object sub-unit respectively formed thereby is deposited; and - onward conveying of the individual, formed strip-shaped or slab-shaped object sub-units; - picking up, holding and conveying the sheet-shaped object by means of the suction effect of suction elements (30, 32) which are arranged on a conveying means which revolves in a belt-like manner, wherein the suction effect of the suction elements (30, 32) is activatable and deactivatable, and wherein the suction elements (30, 32) release the object (P, S) when the suction effect is deactivated; - holding the sheet-shaped object by way of the suction elements (30, 32) in such a manner that in each case at least one suction element (30, 32) engages with the sheet-shaped object between in each case two adjacent weakening regions; - severing in each case the frontmost part, in the conveying direction of the sheet-shaped object, which forms the strip-shaped or slab-shaped object sub-unit from the sheet-shaped object in that, on account of the revolving motion of the conveying means, a suction element (30, 32) which is assigned to said part is pivoted out of the conveying plane of the sheet-shaped object, on account of which said part of the sheet-shaped object, ahead of the in each case frontmost weakening region, is moved out of the conveying plane; and - depositing the formed strip-shaped or slab-shaped object sub-unit in that the suction effect of the suction element (30, 32) which is assigned to the severed object sub-unit is deactivated.
