Abstract: The invention relates to a method, to an application head (1), and to a packaging device for producing strapped packages, each of which is made of at least two grouped articles that are held together by means of at least one strapping band. The method has at least the following steps: providing the at least two grouped articles, which are positioned in a movement and/or handling area of an application head (1); and inserting at least one prefabricated closed strapping band into the application head (1), in which the strapping band is fixed in a defined position. The application head (1) has a variable opening width of a cage (50) which can surround the outer surface of the grouped articles. The application head (1) equipped with the at least one strapping band is then lowered over the articles by means of a feed movement which runs approximately parallel to longitudinal central axes of the articles, wherein the cage (50) of the application head (1) contacts the grouped articles on the outer surface thereof and at least slightly compresses the grouped articles. The strapping band is then positioned at a provided position of the articles by lowering the application head (1), which is simultaneously compressing the articles, in a defined manner. The opening width of the cage (50) of the application head (1) is then increased while the at least one strapping band is simultaneously released and removed from its fixed position within the application head (1) and the application head (1) is raised over the strapped article grouping and is removed therefrom.

Abstract: The invention relates to a method, to an application device (40), and to a packaging device for producing packaging units (13). Each of the packaging units (13) is made of at least two grouped articles (10) which are held together by means of at least one strapping band (15) and by means of at least one packaging blank (60). The method has at least the following steps: providing the articles (10) in a movement and/or handling area of an application head (1); inserting a closed strapping band (15) and a prepared packaging blank (60) into the application head (1); feeding the application head (1) equipped with the at least one strapping band (15) and the at least one packaging blank (60) to the articles (10), said grouped articles (10) being at least slightly compressed; positioning the strapping band (15); securing the packaging blank (60) to the articles (10); opening the application head (1) while simultaneously releasing and separating the at least one strapping band (15) from the fixed position of the strapping band within the application head (1); releasing and separating the at least one packaging blank (60); and removing the application head (1) from the strapped article grouping (12) combined by a packaging blank (60).

Abstract: The invention relates to a method and to a tool for producing strapped packages, in which at least two articles (10) having deformable or flexible lateral surfaces are grouped and brought into a rectangular arrangement and kept together by at least one strapping band (26).
In the method, firstly deformation forces (18) are applied to at least one short side (20) of the group (12) of articles, which deformation forces act approximately uniformly on all articles (10) of the group (12) of articles. Subsequently, the strapping band (26) is placed on the group (12) of articles deformed in this manner, wherein an overall length of the strapping band (26) corresponds to or is minimally greater than an overall circumference of the group (12) of articles subjected to the deformation forces (18).
The deformation forces (18) acting on the group (12) of articles are then removed, as a result of which the lateral surfaces of the articles elastically return to their original shape and bring about a defined band tensioning of the strapping band (26).
The invention also relates to a tool for carrying out the method.
