Abstract
A method and an apparatus are disclosed for wrapping a two-piece foil blank about a group of articles, such as cigarettes, as the group is moved along a given path. The two-pieces, a main blank and a flap blank, are both cut from a single web of wrapping material and transported along different paths to the group of articles. The flap blank is placed on the group of articles as it moves along its path, and as the group contacts the main blank which is placed across its path of travel, it causes the main blank to be wrapped around the group of articles such that it overlaps a portion of the flap blank.

- b. cutting a main blank from said web of material;
- c. cutting a flap blank from said web of material;
- d. feeding said flap blank in a second path to place it on the group of objects;

- and
- f. folding said main blank around said group of objects such that a portion overlaps said flap blank.
Apparatus for wrapping a main blank and a flap blank about a group of objects, such as cigarettes, such that said blanks are disposed in overlapping relationship, wherein said group of objects travels along a first path, comprising:
- a. means to feed a single web of wrapping material from a supply source to the apparatus;
- b. separating means to separate a main blank and a flap blank from said single web of wrapping material;
- c. means to transport said flap blank along a second path and place it on said group of objects;
- d. means to transport said main blank along a third path such that said main blank is placed in a position which intersects the first path of travel of said group of objects;
