Definitions

• the present invention relates to a display device for scrolling a banner of posters along a support and comprising two motorized side winding shafts.
• Devices are already known for scrolling a series of advertising posters on a single location. Such devices are particularly interesting insofar as the urban visual pollution remains controlled, without the advertising activity being affected.
• These display devices have an external structure having a transparent facade behind which scrolls the banner of posters. This poster banner is driven along a transparent support behind which are placed means of lighting the banner poster.
• the posters are arranged one after the other so as to form a banner of posters, each end is attached to a winding shaft.
• the banner is wound on one of the two winding trees, the first poster being then visible through the transparent facade.
• the winding shafts are actuated so as to turn in the direction of scrolling of the banner, one wrapping the banner, the other unwinding it until the next poster is in turn visible through the transparent facade. This operation is repeated until the last poster is presented, then the direction of rotation of the winding shafts is reversed, the banner then being driven in the other direction.
• the object of the present invention is to overcome the drawbacks mentioned above, and for this purpose consists in a display device for scrolling a banner of posters along a support and comprising two motorized lateral winding shafts, characterized in that each winding shaft is provided with fastening means for engaging complementary fastening means provided by a corresponding foil attached to one end of the banner of posters, and in that it is equipped with guiding means for facilitating the scrolling of the banner of posters.
• the display device according to the invention has, thanks to the method of attachment retained, greater ease of installation of the poster banner on the retractor shafts.
• the presence of guiding means makes it possible to prevent any undesirable contact of the banner of posters with an element of the display device, in particular the support, this annihilating any risk of malfunction due to the appearance of static electricity. .
• each winding shaft is equipped, at its two ends, with a flange having at least one slot for cooperating with an end of the associated foil.
• the support has a drilling pattern capable of generating a cushion of air between the banner of posters and said support under the action of at least one blower device.
• the support is plane, and the display device comprises at least one loading roller located in the vicinity of each winding shaft, in front of it and so as to move the poster banner of said support.
