Manufacture of chocolate hollowware by forming a shell in a shaped foil that will later become the packing A foil, preferably 0,2 - 0,3 mm thick polypropylene, is warmed and deep drawn into dies for one set of chocolate halves (possibly 4 x 13). Another set of dies is similarly prepared for the matching halves. The convex faces are then either printed or labels are attached to them. The foils are placed in solid support blocks and filled with an accurately determined amount of chocolate so that, as a set of cooled punches is lowered into the chocolate, a shell of uniform thickness is formed without thinning or excessive overflow. The filled foils are now cooled and the process can be repeated if a second, perhaps differently colored, layer is required. If required, items can then be placed inside the shell. The two halves, in their support blocks, are brought together to connect the two foils. The foils are welded together where flat surfaces overlap and individual articles are separated by a cutting die. The foil is now the packing for the article. |
