The unwinding of many posters in the same advertising street furniture allows to show a great number of sides. The available advertising spaces in town being limited, the unwinding of many posters on the same street furniture increases the potential of the operating location.
The use of tubular motorizations: motorized drums, reduces the space requirement of the device and operates at the same time both sides of the street furniture.
These motorizations have to be highly resistant, operating day and night, winter as summer, in a glassed-in space, with start/off cycles at short intervals of display.
The performances of SIREM motor-driven rollers together with an electronic unit of control must achieve an accurate and smooth display of the sides.
