Abstract
An elevator door leaf formed by a front panel and a rear panel separated from each other but fitted into each other at their longitudinal edges by hemming or seaming, determining a space between the front panel and rear panel that is occupied by an expandable and hardenable foam that is injected under pressure into said space, such that it facilitates the attachment between at least two of the paired longitudinal edges created by fitting the front and rear panels together.

An elevator door leaf formed by a front panel and a rear panel separated from each other but fitted into each other at their longitudinal edges by hemming or seaming, determining a space between the front panel and rear panel that is occupied by an expandable and hardenable foam that is injected under pressure into said space, such that it facilitates the attachment between at least two of the aforementioned paired longitudinal edges created by fitting the front and rear panels together.
A procedure for the manufacture of an elevator door leaf that comprises the forming of a housing with a front panel and a rear panel fitted together by hemming or seaming the longitudinal edges of the front panel with the longitudinal edges of the rear panel, forming a space between the front panel and rear panel, characterized in that an expandable and hardenable foam is injected under pressure into the space between the two panels and is confined under pressure against the front panel and rear panel when it hardens, completely filling the space between the panels.
