DEVICE APPARATUS AND PROCESS FOR WRAPPING AN ITEM IN A CASING OF SHEET MATERIAL

Device and apparatus for wrapping an item (P) in a casing formed by a pair of half-shells (2, 4) of sheeted material with a shape matching respective portions of the outer surface of said item (P) where said half-shells (2, 4) are provided with a respective flange (5, 7) surrounding the respective mouth contour and said flanges (5, 7) are connected together by folding and/or upsetting in such a way as to jointly define said casing, comprising a tool provided with an opening (38) with a profile (40) homologous and widened with respect to the perimeter profile defined by the distal end (5a, 7a) of said flanges (5, 7), said tool (36) being mobile in a direction orthogonal to the plane on which the proximal portion (5b, 7b) of said flanges (5, 7) lies, and also being mobile parallel to the plane of said proximal portion of the flanges, motor means (42) being envisaged arranged to position said caulking tool (36) with the profile (40) of said opening (38) in a surrounding relationship with said angled distal portion (5a, 7a) of said flanges (5, 7) and to bring a section of the profile (40) of said opening (38) into contact with a homologous section of the perimeter profile defined by said angled distal portion of said flanges (5, 7) and to cause a movement of approach towards said item (P) of said section of the profile of said opening (38) in contact with said distal portion (7a) to make it fold further on said proximal portion (5b, 7b) and to repeat the aforesaid operations on further sections of the profile of the distal portion (5a, 7a) of said flanges (5, 7). Un dispositif et un appareil servant à emballer un article (P) dans une enveloppe formée par une paire de demi-coques (2, 4) de matériau en feuille avec des parties respectives de forme correspondante de la surface extérieure dudit article (P) où lesdites demi-coques (2, 4) sont proposées avec une bride respective (5, 7) entourant le contour de bouche respectif et lesdites brides (5, 7) sont connectées ensemble par un pliage et/ou un dérangement de telle manière à définir ensemble ladite enveloppe, comprenant un outil offert avec une ouverture (38) avec un profil (40) homologue et élargi par rapport au profil de périmètre défini par lextrémité distale (5a, 7 a) desdites brides (5, 7), ledit outil (36) étant mobile dans une direction orthogonale au plan sur lequel la partie proximale (5b, 7b) desdites brides (5, 7) repose, et étant également parallèle mobile sur le plan de ladite partie proximale des b
