METHOD FOR DISPLACEMENT OF WEB WITH IMAGES APPLIED THEREON FOR DEMONSTRATION FROM ONE OR MORE OBSERVATION SIDES AND DEVICE TO THIS END

摘要

FIELD: transport.;SUBSTANCE: invention relates to device for demonstration of ad and other info by movable image carrier. Proposed device is composed by flexible resilient web composed by solid flexible strips moving in circle. Said strips are arranged in parallel and articulated along lengthwise faces to endless link chain by means driven parallel pull chains of appropriate length with special joints at said links. Said chain has bearing-guiding system defining the path of said chain at minimum drive force provided with drive mechanism arranged an bearing carcass. Method of motion in circle of one or several webs with pictures allows their securing and static arrangement relative to flexible resilient movable system. Said system transfers loads caused by external effects and its weight to said webs. This is effected by placing it at endless flexible web moving in preset path relative to observer and bearing surface. Said system consists of articulated sold elastic links of adequate mechanical, physical and geometrical parameters sufficient for attachment of web material thereat, taking up and redistribution of forces in the system and thereat.;EFFECT: operation without protection against external effects, observation of pictures from whatever side, higher wear resistance.;2 cl, 4 dwg
