The present invention relates to a method and a device for folding a foil material half-shell edge which protrudes from a surface of the packaging of a packaged food product, said half-shells receiving the food product. The half-shells have flanges, at least some regions of which lie one on top of the other and which form the protruding edge. The aim of the invention is to improve a quick and reliable method which can be carried out with little effort for improving the appearance of food products packaged in foil half-shells. This is achieved in that during a relative movement between a packaged food product and a die, an edge region of the die presses against the protruding edge of the foils, whereby the edge of the foils is at least partly folded to lie substantially flush on one of the half-shells. The invention further relates to a device which corresponds to the method.
Method for folding an edge (4) of half-shells (2) of a foil-like material protruding from a surface of the packaging of a packaged food product (1) in which the food product (1) is received to lie substantially flush, wherein the half-shells (2) comprise flanges (3) lying one on top of the other at least in some sections and forming the protruding edge (4),
Method according to one of the preceding claims, characterized in that at the edge region (8) of the die, bristles press onto the edge (4) of the foils, whereby the edge (4) of the foils is at least partially folded to lie substantially flush at at least one half-shell (2).
Method according to one of the preceding claims, characterized in that the die (5) is at rest and the packaged food product (1) is moved relative to the die (5) through the opening (7), or that the packaged food product (1) is at rest and the die (5) is moved relative to the packaged food product (1).
Method according to one of the preceding claims, characterized in that the edge (4) of the foils is, during the passage through the opening (7) of the die (5), in a first step initially approached to the surface of the half-shells (2), and subsequently, in a further step, folded to lie substantially flush at at least one half-shell (2).
Method according to one of the preceding claims, characterized in that the relative movement between the die (5) and the packaged food product (1) extends one-dimensionally.
Method according to one of the preceding claims, characterized in that the packaged food product (1) is moved relative to the die (5) with the aid of guide means (6).
Method according to one of the preceding claims, characterized in that the protruding edge (4) has a proximal section (14) which is directly connected to the half-shells (2) and connects a distal section (15) of the edge with the half-shells (2), wherein the distal section (15) is folded onto the proximal section (14) before the folding of the edge to lie substantially flush.
Method according to one of the preceding claims, characterized in that the flanges (3) are bordered and/or sealed to each other before the folding of the edge (4) to lie substantially flush.
Method according to one of the preceding claims, characterized in that the packaged food product (1) completely passes through the die (5).
Device for folding an edge (4) of a packaged food product (1) to lie substantially flush, which comprises
