Abstract

The panel, comprising a paper or fabric strip (1) passing round rollers (2, 3) and driven by an asynchronous motor (7) via a pulley (4, 5) and belt (6) system, has an upper steel gravity roller (14) on two pivoted cantilever arms (19) that ensure the tension of panel by pressing against its horizontal upper section. The system also has two guide rollers (11, 12) and an assembly of three sensors (15, 16, 17) to determine the direction of the panel's rotation and a tension detector (18) to ensure that it is not over-tensioned.

Panneau d'affichage deroulant La presente invention est relative aux panneaux d'affichage deroulants. Plus particulierement, I'invention concerne un panneau d'affichage de bande support d'affiches de falble longueur finie enroulee sur deux arbres paralleles et entraines de facon synchronisee par un motoreducteur asynchrone unique, Le defilement d'affiches sur un tel panneau d'affichage deroulant reste simple de conception done peu onereux et de maintenance reduite mais engendre un flottement important du support d'affches. D'autres panneaux d'amchage deroulants a ['inverse tres sophistiques utilisant des freins ou embrayages pour realiser la tension de bande, bien que presentants de bonnes qualites de tension du support d'affches, s'averent onereux, d'une maintenance plus specifique ainsi que d'une duree de vie  Roll-up display panel The present invention relates to roll-up display panels. More particularly, the invention relates to a display panel of a support panel for falble posters of finite length wound on two parallel shafts and driven in synchronism by a single asynchronous gearmotor, The scrolling of posters on such a display panel rolling down remains simple in design therefore inexpensive and low maintenance but generates a significant floating of the support of posters. Other very sophisticated reverse rolling landing panels using brakes or clutches to achieve the tension of the strip, although having good qualities of tension of the poster support, prove to be expensive, of more maintenance. specific as well as a lifetime

Le panneau d'affchage deroulant suivant ['invention propose une solution intermediaire qui lui confere la caracteristique d'etre a la fois simple de conception et de maintenance reduite tout en proposant un dispositif de tension de bande efficace. 11 comporte en effet selon une premiere caracteristique un ensemble de rouleaux guides en PVC montes sur roulement a billes permettant le deport de la bande support sans zone visible de surepaisseur resultant des couches successives de bande  The drop-down display panel according to the invention provides an intermediate solution which gives it the characteristic of being both simple in design and reduced maintenance while providing an effective belt tensioning device. 11 in fact comprises, according to a first characteristic, a set of PVC guide rollers mounted on ball bearings allowing the offset of the support strip without visible area of excess thickness resulting from successive layers of strip

A cette zone de pre-tension de l'affichage, delimitee par l'entraxe des rouleaux guides, est associe un bras oscillant qui produit 1'appui continu sur la bande support ce qui maintient tendu l'affichage entre les rouleaux guides. Selon des modes particuliers de reaiisation: - le bras oscillant peut etre constitue d'un rouleau pantin supporte  This pre-tensioned display area, delimited by the center distance of the guide rollers, is associated with an oscillating arm which produces continuous support on the support strip, which keeps the display taut between the guide rollers. According to particular modes of reaiisation: - the swinging arm can be constituted by a supported puppet roller

Avantageusement, le dispositif comprend un moyen de tension de bande comprenant un rouleau pantin en acier monte sur roulements a billes qui permet au bras oscillant d'appliquer un effort presseur sur la bande sans friction relative de la bande sur le rouleau puisque ce dernier est entrane en rotation par ladite bande. Au dit moyen est associe idealement un capteur de controle de tension de bande permettant d'eviter la rupture du  Advantageously, the device comprises a belt tensioning means comprising a steel dummy roller mounted on ball bearings which allows the swinging arm to apply a pressing force on the band without relative friction of the band on the roller since the latter is driven in rotation by said strip. Said means is ideally associated with a tape tension control sensor to prevent breakage of the
