(57) The invention relates to adhesive insertion pockets of a web material where used
as the basis is a self-adhesive material, for instance a reinforced paper web (102a)
which has been detachably attached to a web shaped substrate (101). By means of appropriately
punching or incising the paper web, a piece for an insertion pocket (102b) emerges
which, on being torn from the substrate (101) and being adhered for instance to the
inside cover of a book (108) will form an insertion pocket where an incision for the
mouth (103a) forms the mouth of the pocket and the size of the pocket is determined
by a cut away section (104) on the substrate web (101) which when detached, remains
on the piece for the insertion pocket (102b) to form a non-adhesive area of the pocket.
In order to achieve ready entry of the card (110) to be inserted into the pocket,
the entrance incision has been made as an elongated circumferential opening incision
(103a), and to achieve an area at the bottom of the pocket (104c) affected as little
as possible by exposure of zones of glue, penetrating incisions (104s, 104m) have
been made in the area of the bottom of the pocket, reducing this bottom area and
thus reducing the possibility of adhesion by the cards to the bottom of the pocket.
