Method and apparatus for the introduction of a cover plate between a transparent film and a books similar cassette

摘要

A method for 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 (41, 4b) by an angle wider than 180°; detaching the transparent film (3) from the outer surface of said closure members (41, 4b); making a transversal corrugation in a cover sheet (2) situated beside said opened container (4), near an area (Z) delimited by said opened members (41, 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.
