A method for formation of a compacted arrangement of articles to be packaged within a packaging machine, whereby the group of articles come into contact with and is guided through the packaging machine via at least one profiled bar, at least in a partial section of its transport route, which comes into contact with an end face of the group of articles and in doing so at least some of the articles of the group are pushed together in the compacted arrangement. A device for implementation of the method for formation of a compacted group of a plurality of the same type of articles to be packaged. A symmetrically or asymmetrically profiled thrust bar for transforming a group of articles being conveyed in a horizontal direction into a compacted arrangement.

1. A method for formation of a nested compacted arrangement of articles to be packaged, sub-divided into groups, preferably as a plurality of rows of articles arranged one after the other, preferably the same type of articles, in particular cylindrical articles within a packaging machine, the group of articles being guided through the packaging machine via at least one regularly or irregularly profiled or asymmetrically formed bar, at least in a partial section of its transport route, in particular in a conveying direction, along the side walls in a tapered area which comes into contact with an end face of the group of articles, in particular in a conveying direction at the rear side of the group of articles and in doing so at least some of the articles of the group are pushed together into the nested compacted arrangement; wherein a front edge of the at least one bar is profiled to define a profiling, the profiling corresponding with an outer contour of the group of articles being pushed into the nested compacted arrangement, the profiling including a wave or cam profile with alternating depressions and cams at a defined distance in the conveying direction of less than an article diameter, the profile having flanks between the depressions and cams, wherein in the nested compacted arrangement each of the depressions accommodates and article while each cam is also in contact with an article, and wherein while guiding the articles into the nested compacted arrangement, the articles slide along the flanks. 2. The method according to claim 1 in which the partial section of the transport route with the tapered side walls has a contact surface for sliding pushed movement of the articles which are pushed from the rear side of the group in the direction of transport through contact with the profiled bar acting as a thrust bar. 3. The method according to claim 1 in which the articles are conveyed in a plurality of single rows travelling parallel to each and separated from each other in a horizontal direction and which are transferred in conveying direction along the side walls to a tapered area without lane separators within which every group of a plurality of articles is subjected to offsetting and/or shifting movements of the articles relative to each other in a plurality of conveying directions through the action of the profiled thrust bar moved towards the group from the rear to bring them into the compacted arrangement. 4. The method according to claim 1 in which the rear-most articles of each group, with the profiled thrust bar engaging, while moving along the tapered area, adjust their position to the contouring of the thrust bar and are shifted into the nested compacted nest like arrangement. 5. The method according to claim 1 in which, after shifting the articles, the rear articles of a row viewed in the direction of transport are in a depression on the profiled thrust bar and the rear articles of a neighbouring row viewed in the direction of transport come into contact with a projection or cam on the thrust bar. 6. The method according to claim 1 in which the partial section of the transport route with the tapered side walls has a transport plane with a moving contact surface for upright transport of the articles where the articles are slowed through the action of pushing against the direction of transport by a profiled stop bar at the front side of the group. 7. The method according to claim 6 in which the front articles of each group adjust their position, with the profiled stop bar engaging during this contact along the tapered section, to the contouring of the stop bar and are shifted into the nested compacted arrangement. 8. The method according to claim 6 in which, after shifting the articles, the front articles of a row viewed in the direction of transport are in a depression on the profiled stop bar and the front articles of a neighbouring row viewed in the direction of transport come into contact with a projection or cam on the stop bar. 9. The method according to claim 1 in which a side movement of single articles occurs due to a movement component perpendicular to the conveying direction while moving the articles. 10. The method according to 18 in which at least one of the rows of articles to be moved is subjected to a movement component acting at the side by means of an element mounted movable on the bar. 11. The method as recited in claim 1 wherein the articles to be packaged are a plurality of rows of articles arranged one after the other. 12. The method as recited in claim 1 wherein the articles to be packages are a same type of articles. 13. The method as recited in claim 12 wherein the articles are cylindrical articles. 14. A device for implementation of the method for formation of a nested compacted arrangement of articles to be packaged, sub-divided into groups, preferably as a plurality of rows of articles arranged one after the other, preferably the same type of articles, in particular cylindrical articles within a packaging machine, according claim 1, with a transport route for the group of articles which at least in a partial section in the conveying direction tapered along the side walls and where at least one profiled bar can be brought into contact with an end face of the group of articles, in particular in conveying direction, at the rear side of the group of articles to transform the articles into a compacted arrangement, at least one bar having a profiling pointing towards the group of articles, the profiling corresponding with an outer contour of the nested compacted arrangement of the articles; the profiling including a wave or cam profile with alternating depressions and cams at a defined distance in the conveying direction of less than an article diameter, the profile having flanks between the depressions and cams, wherein in the nested compacted arrangement each of the depressions accommodates and article while each cam is also in contact with an article, and wherein while guiding the articles into the nested compacted arrangement, the articles slide along the flanks. 15. The device according to claim 14 in which the number of profiled bars on the side along the transport route for the articles are arranged on endlessly circulating traction elements. 16. The device according to claim 14 in which a profiled pushing bar or a un-profiled stop bar which should come into contact with the front articles at a front side of each group of articles is arranged to move with the group along the conveying direction. 17. A profiled pushing or stop bar to transform a group of articles being conveyed in a horizontal direction into a pre-defined, compacted, in particular nested arrangement, which has a profiling pointing towards the group of articles which corresponds with an outer contour of the nested arrangement of the articles, the profiling including a wave or cam profile with alternating depressions and cams at a defined distance in the conveying direction of less than an article diameter, the profiling having flanks between the depressions and cams, wherein in the nested arrangement each of the depressions accommodates and article while each cam is also in contact with an article, and wherein while guiding the articles into the nested arrangement, the articles slide along the flanks. 18. The pushing or stop bar according to claim 17 which is made up of a plurality of parts and at least two bar parts are moving relative to each other whose sum profile can be altered according to the relative position of at least two bar parts. 19. The pushing or stop bar according to claim 17 which has an unsymmetrical wave or cam profile for which the alternating depressions and cams each have a suitable profile height which is approximately half of the external diameter of an article or less and which each has a distance between them which represents the external diameter of an article or less. 20. The pushing or stop bar according to claim 17 which has a movable and/or manually adjustable and fixable guide element acting against the force of a spring on at least one side flank of a cam to apply a movement component acting from the side to the moving rows of articles.
