Method for producing an insert leaf for a book-like document
The invention relates to a method for producing an insert leaf for a book-like document, in particular to a method for producing a data page for an identification document. In order to achieve a straightforward method for producing an insert leaf ( 11 ), it is proposed for at least one hinge film ( 17, 18 ) to be provided, right from the start, as a constituent part of an insert-leaf blank ( 19 ) and for that part ( 22 ) of the insert-leaf body which is not required to be separated off, in order to produce the hinge region ( 12 ).
1 .- 10 . (canceled)
11 . A method for producing an insert leaf for a book-like document, the insert leaf having a main body and a hinge region, said method comprising the steps of:
connecting a number of films to form an insert leaf sheet; wherein the films comprise at least one hinge film;
separating an insert leaf blank from the insert leaf sheet to form a main body of the insert leaf;
removing a portion of the insert leaf main body for creating a hinge region at the main body such that the hinge region projects beyond a periphery of the main body; wherein the hinge region comprises the at least one hinge film.
12 . The method according to claim 11 , wherein connecting the films to form the insert-leaf sheet takes place in a single operation.
13 . The method according to claim 11 , wherein separating the portion of the insert leaf main body takes place in a single operation.
14 . The method according to claim 13 , wherein the single operation is carried out by a machining step.
15 . The method according to claim 11 , further comprising that during the step of connecting the films to form the insert leaf sheet, a separating film is arranged between the at least one hinge film and the rest of films in the region of the insert leaf sheet that subsequently serves as the hinge region, wherein the separating film, during the separating step, is drawn off from the at least one hinge film together with the portion which is to be separated off.
16 . The method according to claim 15 , wherein the act of drawing off the separating film is carried out by subjecting the portion to be separated to a pulling force.
17 . The method according to claim 15 , wherein, prior to drawing off the separating film, a separating groove is introduced into the portion to be separated off, said groove determining the course of the hinge region.
18 . The method according to claim 11 , wherein, during the step of removing the portion of the insert-leaf body, a portion of the hinge region adjacent to the main body is formed as a transition region, said transition region preventing removal of the at least one hinge film from the insert leaf without damaging the insert leaf.
19 . The method according to claim 18 , wherein a side edge of the main body extends into the hinge region obliquely in relation to a surface of the at least one hinge film.
20 . An insert leaf produced by a method comprising the steps of:
connecting a number of films to form an insert leaf sheet; wherein the films comprise at least one hinge film;
separating an insert leaf blank from the insert leaf sheet to form a main body of the insert leaf;
removing a portion of the Insert leaf main body for creating a hinge region at the main body such that the hinge region projects beyond a periphery of the main body; wherein the hinge region comprises the at least one hinge film.
21 . A book-like document, in particular identification document, comprising at least one insert leaf produced by the steps of:
connecting a number of films to form an insert leaf sheet; wherein the films comprise at least one hinge film;
separating an insert leaf blank from the insert leaf sheet to form a main body of the insert leaf;
removing a portion of the insert leaf main body for creating a hinge region at the main body such that the hinge region projects beyond a periphery of the main body; wherein the hinge region comprises the at least one hinge film.
