  • the half shells have abutting connecting flanges, which are then sealed together and form an upstanding from the surface edge.
  • Subsequent application of the so-called Saturn ring is mentioned as optional in WO 93/01093.
  • DE 1 260 949 describes a method for producing figures of confectionery masses enveloped with thin metal foils. The result is a crimped connection between two preformed film half-shells, which have protruding edges. The edges are first stacked, then folded up in one direction and finally over an inner edge area folded. There remains a radially protruding edge with increased rigidity

Furthermore, by the easily designable process control, which essentially relates to the control of the relative movement, an automation of the process can be implemented conveniently.

  • the edge Before the final application to the surface of the partial shells, the edge can first be preformed in a controlled manner, for example in order to approximate the shape of the edge to be applied to the outer contour of the partial shells. In some packages and materials, it has been found to be more favorable for tidy application of the edge, if one chooses a step-by-step method of application which better accommodates the deformation behavior of the edge.

Different sections on which elastic elements and / or bristles are located can alternate with sections of the edge area which are rigid, ie act without elastic element or bristles on the edge. It is also possible to combine elastic elements, bristles and rigid portions of the edge portion so that they act sequentially on the edge, thus realizing a stepwise application and pressing of the edge.

Abstract

L'invention concerne un procédé et un dispositif d'application d'un bord de coques partielles d'un matériau de type film qui est en saillie à partir d'une surface de l'emballage d'un produit alimentaire emballé, les coques partielles logeant le produit alimentaire et présentant au moins par endroits des brides superposées formant le bord faisant saillie. L'invention vise à améliorer un procédé fiable, rapide et à mettre en œuvre avec peut de moyens afin d'améliorer l'apparence de produits alimentaires emballés dans des coques partielles de type film. À cet effet, pendant un mouvement relatif entre un produit alimentaire emballé et une matrice, une zone de bordure de la matrice appuie sur le bord faisant saillie du film, de sorte que le bord du film est au moins en partie appliqué sur une des coques partielles. L'invention concerne par ailleurs un dispositif correspondant au procédé.
