A gripper device brings the cans or tubes in groups according to the desired number of pieces in a packaging layer to a delivery station. Each can or tube is deposited into a support element, after which the cans or tubes are pushed together out of the support elements into a loading station. The cans or tubes are placed at equal distances into the pick-up elements, wherein individual support elements are placed apart from each other at a predetermined distance. The cans or tubes are then deposited into the support elements at distances predetermined by the pick-up elements. The support elements are subsequently moved together until they touch each other, whereupon the cans or tubes are then pushed into the loading station. This method allows the use of the same apparatus for different can diameters with minimal changing effort. ## Claims ### Claim 1 In a method for packaging a plurality of cans or tubes, which are continuously moved in steps from a production installation into a plurality of pick-up elements (31) of an intermediate station (3), wherein a gripper device (4) delivers the cans or tubes grouped in a packaging layer in accordance with a desired number to a delivery station (5), where each tube or can is placed into one of a plurality of support elements (51) and then moved together by the support elements into a loading station (7), the improvement comprising: depositing the cans or tubes at evenly spaced distances into the pick-up elements (31); depositing the cans or tubes upon the individual support elements (51), which are spaced apart from each other at a distance predetermined by the pick-up elements (31); and subsequently moving the support elements (51) toward each other until the support elements (51) touch and the cans or tubes which are pushed into the loading station (7). ### Claim 2 (depends on 1) The method in accordance with claim 1, wherein before being pushed into the loading station (7), the support elements (51) bring the cans or tubes into a desired position with respect to the loading station (7). ### Claim 3 (depends on 2) The method in accordance with claim 2, wherein a position of the cans or tubes with respect to the loading station (7) is in a horizontal direction, and the loading station (7) is positioned in a vertical direction. ### Claim 4 (depends on 1) The method in accordance with claim 1, wherein the gripper device (4) transports the cans or tubes by means of vacuum aspiration. ### Claim 5 (depends on 1) The method in accordance with claim 1, wherein the cans or tubes are maintained on the support elements (51) by means of vacuum aspiration. ### Claim 6 (depends on 1) The method in accordance with claim 1, wherein a center support element (51) of the support elements (51) remains stationary. ### Claim 7 In an apparatus for packaging a plurality of cans or tubes, the apparatus having an intermediate station (3) with a plurality of pick-up elements (31) which are moved in steps, a gripper device (4), a delivery station (5) with a plurality of support elements (51), and a pusher (6), the improvement comprising: the intermediate station (3) having an endless prismatic belt (30), a plurality of pick-up elements (31) formed by spaces of the prismatic belt (30); and the support elements (51) displaceably positioned with respect to each other, and means (52) for defining a maximum distance of the support elements (51) with respect to each other. ### Claim 8 (depends on 7) The apparatus in accordance with claim 7, wherein the support elements (51) each comprise a support plate (512) and an interchangeable deposit dish (510) removably mounted with respect to the support plate (512), for receiving the cans or tubes. ### Claim 9 (depends on 7) The apparatus in accordance with claim 7, wherein the support elements (51) are connected with respect to each other by a chain (52) which determines the maximum distance of the support elements (51) with respect to each other. ### Claim 10 (depends on 7) The apparatus in accordance with claim 7, wherein the support elements (51) are displaced by at least one pneumatically operated drive rod (53). ### Claim 11 (depends on 7) The apparatus in accordance with claim 7, wherein a plurality of drive rods (53) each actuates adjoining support elements (51) of the support elements (51). ### Claim 12 (depends on 7) The apparatus in accordance with claim 7, wherein the intermediate station (3) and the delivery station (5) are arranged in a line perpendicular to the arrangement directions of the pick-up elements (31) and the support elements (51).
