Method for manufacturing a picture- and/or textchanging slide, and a picture- and/or textchanging slide as obtained by applying this method

摘要

Method for manufacturing a picture- and/or textchanging slide, in which a piece of planar material is subdivided into three sections, of which two sections provided with changing strips formed by incisions are folded onto each other and are moved on over a transport track and over one or more pushing means, by which the free ends of the changing strips of the one section are brought onto the other sections through the incisions thereof, then two sections are folded together into an envelope while enclosing the third section and glueed together with a marginal portion of the third section, after which the slide is cut loose from the third section.
