Method and apparatus for inserting a cover sheet between a transparent film and a book-like case

摘要

A method fox introducing a cover sheet (2) between a transparent sheet (3) and a book-like container (4), which is substantially formed by a pair of closure members (4a, 4b), externally wrapped within the film (3), includes: ;opening the container (4) by opening said closure members (4a, 4b) by an angle wider than 180°; ;detaching the transparent film (3) from the outer surface of said closure members (4a, 4b); ;making a transversal corrugation in a cover sheet (2) situated beside said opened container (4), near an area (2) delimited by said opened members (4a, 4b) and the detached film (3); ;introduction of gripping means (10), situated on a side opposite with respect to said corrugated cover sheet (2), into said area (Z); ;gripping said corrugated cover sheet (2) and pulling it, by said gripping means (10), into said area (Z); ;releasing said cover sheet (2) into said area (Z), which cover sheet consequently spread across said area Z; ;defining a flattened configuration of the closure members (4a, 4b) so that said cover sheet (2) spreads over a plane.
