Definitions

• the present invention relates to advertising consisting of paper advertising posters or other printing medium arranged one after the other in ribbon and relates to an unwinding system for such posters.
• Patent FR-A-2 205 243 discloses a system with two drums driven by a chain winding a film of flexible polyester, fabric or fabric. On this film can be glued, welded or stapled symbols, numbers or letters. This system is only valid for images, texts or signals of small dimensions because entire posters, glued or stapled, would crumple or tear during winding.
• the problem of transporting the ribbon carrying the posters is solved according to the invention because the transport ribbon is made of polyethylene terephthalate.
• the transport tape according to the invention made of polyethylene terephthalate has several advantages. By its quality of perfect insulator it causes a very high electrostatic adhesion with the posters while constituting at the same time an ideal support for them.
• Such a transport tape is very flexible and very resistant to wear and tear. It is 100% transparent, which is necessary for lighting posters with neon tubes. Its measurements are stable under various conditions, that is to say stretched with great force under temperatures which can vary from - 20 ° C to 100 ° C, it is completely insensitive to humidity.
• Posters made of paper or other printing medium are loaded on the transport tape per unit without being stuck thereon, which allows to easily replace one or the other of the posters unlike the current system consisting of a strip formed of several posters connected to each other.
• each poster is attached separately to its four corners on the transport tape by a flexible and self-adhesive strip element, in order to allow a slight displacement of the poster on the support caused by the winding and the guarantee of an automatic return to place.
• the support tape with narrow vertical flaps made of the same material as the support tape and fixed on the said tape, so as to leave a housing between the tape and the flap.
• the unwinding system according to the invention is further characterized in that it comprises a system for guiding the conveyor belt consisting of an endless ribbon stretched around the return axes and driven by the conveyor belt carrying the posters. .
• the invention also relates to an arrangement of the reels in a system for unrolling double-sided advertising posters.
• This arrangement is characterized in that the coils on one side are arranged in line with respect to the coils on the other side.
• FIG. 1 a perspective view of an advertising monolith produced according to the invention
• Figure 2 a perspective view of a double-sided advertising monolith according to the invention.
• the advertising monolith represented in FIG. 1 consists of two coils 1, 2 and two return axes 3,4. On these reels 1, 2 is wound back and forth a transport tape 5 of polyethylene glycol terephthalate.
• the coils are driven (not shown) by direct stepping motors on the coils with optical and magnetic positioning device.
• the motors are controlled by computer with an interchangeable program.
• This fixing is carried out in such a way that it leaves along the flap or the tab a housing 7 for the insertion of the lateral edge of the poster S.
• the poster is held in place while being able to be move slightly horizontally left and right when unrolling.
• the posters 8 are fixed at their four corners by elements 9 of self-adhesive and flexible tape, this so as to allow a slight displacement of the poster caused by the winding Lement and to obtain the guarantee of an automatic return to place.
• an endless tape 10 is stretched around the return axes 3, 4.
• This tape is also produced according to the invention in polyethylene glycol terephthalate.
• This endless ribbon acts as a support and support when it comes to placing the poster 6 on the transport tape 5. It prevents any movement outside the axis of the unwinding by ensuring b i e n parallel transport.
• the arrangement is such that the coils 1, 2 on one side are arranged in line with respect to the coils 1 ', 2' on the other side. This gives a greatly reduced overall size which is advantageous from several points of view for the environment, whether in terms of the es aesthetic or visibility for example.
