Abstract

The unit consists of a support (8) containing two caps (7). The support shaft (1) is fixed to the support by these end caps which contain bearing sleeves (6) which enables the shaft to freely rotate. This shaft (1) passes through two scored face rollers (2), the spacers (3) and a central cutting roller (4). The assembly is held on the shaft by the nuts (5) located at either end of this shaft, and the central roller has associated with it a cleaning spring (10). On the end edges of the rotating panels (14) are metal strips (13) between which the cutting roller (4) engages and by a backwards and forwards motion of the cutting unit the paper between the strips (13) is cut. USE/ADVANTAGE - For the cutting up into sections at the joints, paper posters pasted to double sided poster boards with rotary elements without the need of dismantling them, which can be carried out whilst the paper is still wet.

Description

La présente invention concerne un dispositif de coupe manuel à galets permettant de découper sur place une affiche encore mouillée par le collage, sur un type particulier de panneau d'affichage à éléments tournants. Ces éléments sont munis de feuillards inox venant en saillie de leur surface affichable et correspondent avec le dispositif de coupe en question. The present invention relates to a manual cutting device with rollers for cutting on the spot a poster still wet by gluing, on a particular type of display panel with rotating elements. These elements are provided with stainless steel strips projecting from their displayable surface and correspond with the cutting device in question.

Ces éléments particuliers faisant parties d'un dispositif d'affichage à éléments tournants protégé par un dépôt de brevet différent. These particular elements being part of a display device with rotating elements protected by a different patent filing.

La coupe de l'affiche sur les différents types-de;panneaux à éléments tournants actuellement commercialisée nécessite le démontage, le nettoyage de ces éléments, l'affichage en atelier et le séchage complet de l'affiche ainsi collée avant la coupe entre les éléments. Ces manipulations occasionne une grosse perte de temps et rendent l'exploitation publicitaire de ces dispositifs en affichage traditionnel papier pratiquement impossible. The cutting of the poster on the different types of; panels with rotating elements currently marketed requires disassembly, cleaning of these elements, display in the workshop and complete drying of the poster thus glued before cutting between the elements . These manipulations cause a big loss of time and make the advertising exploitation of these devices in traditional paper display practically impossible.

Le dispositif de coupe selon l'invention permet de remédier à cet inconvénient, car en effet selon une première caractéristique le dispositif coupe l'affiche encore mouillée directement sur le panneau sans l'attente du séchage. Ce panneau bien sûr muni des éléments spécialement conçus et comportent des feuillards qui correspondent avec les 3 galets du dispositif de coupe illustré sur la figure 2. Deux de ces galets sont striés et permettent de plaquer l'affiche pendant qu'un troisième galet tranchant placé entre les deux autres vient couper le papier passant sur le bord des feuillards venant en saillie des supports d'affichage, par un mouvement de rotation produit un effet de ciseau bilatéral supprimant la portion d'affiche se trouvant entre les éléments. The cutting device according to the invention overcomes this drawback, because indeed according to a first characteristic the device cuts the poster still wet directly on the panel without waiting for drying. This panel of course provided with specially designed elements and includes strips which correspond with the 3 rollers of the cutting device illustrated in FIG. 2. Two of these rollers are striated and allow the poster to be plated while a third cutting roller placed between the two others comes to cut the paper passing on the edge of the strips projecting from the display supports, by a rotation movement produces a bilateral scissor effect eliminating the poster portion located between the elements.

Selon des modes particuliers de réalisation - Les deux galets striés peuvent être réalisés en aluminium acier ou plastique. According to particular embodiments - The two ridged rollers can be made of aluminum, steel or plastic.

- Le support (8) delta figure 2 peut être réalisé en acier ou aluminuim.- The support (8) delta Figure 2 can be made of steel or aluminuim.

Les dessins annéxés illustrent l'invention
La figure 1 représente en section A et F le dispositif.The attached drawings illustrate the invention
Figure 1 shows in section A and F the device.

La figure 2 représente la coupe du dispositif.Figure 2 shows the section of the device.

En référence à ces dessins, le dispositif de coupe est composé de deux galets (2) striés placés de part et d'autre d'un galet central (4) celui ci tranchant sur ses deux bords extérièurs. With reference to these drawings, the cutting device is made up of two striated rollers (2) placed on either side of a central roller (4), this cutting edge on its two outer edges.

Le galet central (4) est séparé des deux autres par les entretoises (3) ayant l'épaisseur nécessaire pour permettre au galet central (4) de s'incérer entre les deux feuillards (13) dépassant les supports d'affiches (14) ces trois galets et ces deux entretoises ainsi montés sur la figure 2 sont traversés par l'axe (1) et serrés ensemble de façon fixe par les écrous (5).The central roller (4) is separated from the other two by the spacers (3) having the necessary thickness to allow the central roller (4) to be inserted between the two strips (13) projecting from the poster supports (14) these three rollers and these two spacers thus mounted in FIG. 2 are crossed by the axis (1) and tightened together in a fixed manner by the nuts (5).

Cet ensemble ainsi formé est muni à chaque extrémité de l'axe (1) d'un chapeau de fixation (7) où est encastrée la bague (6) permettant à l'axe (1) de tourner librement dans ces chapeaux servant à fixer l'ensemble des galets sur le support (8) à l'aide des vis (11) le support (8) est muni d'une traverse surplombant les galets où se trouve le ressort clinquant en acier dur (9) fixé par les vis (10). Le ressort vient en appui sur le galet central (4) vue section A et sert au nettoyage de ce galet pendant la coupe. Cet ensemble ainsi formé vient s'incérer entre les feuillards (13) des éléments (14) et par un mouvement de bas en haut produit un effet de ciseau bilatéral supprimant la portion d'affiche se trouvant entre les éléments. Le support (8) est surt monté d'un manchon (12) qui permet au dispositif de coupe d'être fixé sur une perche en fibre de verre souvent utilisée dans l'affichage. This assembly thus formed is provided at each end of the axis (1) with a fixing cap (7) where the ring (6) is embedded allowing the axis (1) to rotate freely in these caps used to fix all the rollers on the support (8) using the screws (11) the support (8) is provided with a cross member overhanging the rollers where the hard steel foil spring (9) is located fixed by the screws (10). The spring comes to bear on the central roller (4) seen in section A and is used for cleaning this roller during cutting. This assembly thus formed is inserted between the strips (13) of the elements (14) and by a movement from bottom to top produces a bilateral scissor effect eliminating the poster portion located between the elements. The support (8) is further mounted with a sleeve (12) which allows the cutting device to be fixed on a fiberglass pole often used in display.

Dans la forme de réalisation selon la figure 2 le galet central tranchant (4) est d'un diamètre légèrement inférieur aux deux galets striés (2) ceci pour permettre à ces deux galets de maintenir le papier avant que le galet central (4) ne le tranche. In the embodiment according to Figure 2 the cutting central roller (4) is slightly smaller in diameter than the two ridged rollers (2) this to allow these two rollers to hold the paper before the central roller (4) the slice.

A titre d'exemple non limitatif les galets ont une dimension de 45 millimètres de diamètre. By way of nonlimiting example, the rollers have a dimension of 45 millimeters in diameter.

Le dispositif selon l'invention est particulièrement destiné à la coupe sur place d'une affiche encore mouillée sur un panneau d'affichage à éléments tournants, mais il peut éventuellement s'adapter à d'autre corps de métier exemple ( tapissier ect...) The device according to the invention is particularly intended for cutting on the spot a poster which is still wet on a display panel with rotating elements, but it can optionally be adapted to other example trades (upholsterer ect. .)
