A method used to handle piece goods being moved one after another in at least two rows in order to produce a palletisable layer arrangement, in which method the piece goods are in each instance transported in the particular rows immediately consecutively without spaces or with minimal spaces as closed formations to a plurality of manipulators, characterised in that, in order to produce the palletisable layer arrangement with piece goods being brought and/or rotated into their particular target position and/or target alignment in a plurality of manipulation steps, - piece goods are in each instance seized by the plurality of manipulators from the at least two closed formations in a clamping and/or force-locking and/or form-locking manner, are spatially separated from the particular closed formation, and are in this context brought in an at least temporarily temporally overlapping manner into a particular defined relative target position and target alignment of the layer arrangement in relation to subsequent piece goods by the plurality of manipulators, - wherein the piece goods being transported in the at least two closed formations of the at least two rows are seized by two or more manipulators arranged adjacent and/or parallel next to each other, and are brought into the particular target positions and target alignment of the layer arrangement, - wherein the seizing ranges assigned to the at least two adjacently and/or parallelly arranged manipulators have common and/or overlapping areas, - wherein the piece goods, once having been seized by one of the manipulators (5a, 5b), are in each instance transferred, pushed, or rotated in one single, interruption-free manipulation step into their particular target position and target alignment of the layer arrangement, and - wherein at least one manipulation step in the production of the palletisable layer arrangement provides that the piece goods, once having been seized by one of the manipulators (5a, 5b), are in each instance transferred, pushed, and rotated in one single, interruption-free manipulation step into their particular target position and target alignment of the layer arrangement. - piece goods are in each instance seized by the plurality of manipulators from the at least two closed formations in a clamping and/or force-locking and/or form-locking manner, are spatially separated from the particular closed formation, and are in this context brought in an at least temporarily temporally overlapping manner into a particular defined relative target position and target alignment of the layer arrangement in relation to subsequent piece goods by the plurality of manipulators, - wherein the piece goods being transported in the at least two closed formations of the at least two rows are seized by two or more manipulators arranged adjacent and/or parallel next to each other, and are brought into the particular target positions and target alignment of the layer arrangement, - wherein the seizing ranges assigned to the at least two adjacently and/or parallelly arranged manipulators have common and/or overlapping areas, - wherein the piece goods, once having been seized by one of the manipulators (5a, 5b), are in each instance transferred, pushed, or rotated in one single, interruption-free manipulation step into their particular target position and target alignment of the layer arrangement, and - wherein at least one manipulation step in the production of the palletisable layer arrangement provides that the piece goods, once having been seized by one of the manipulators (5a, 5b), are in each instance transferred, pushed, and rotated in one single, interruption-free manipulation step into their particular target position and target alignment of the layer arrangement.
