Abstract

The container, designed to hold a supple photopolymerisable resin for making marker pads or plates which receive an imprint, has two faces made from UV-transparent films of different materials - one which grips the resin to form the base of the pad or plate, and the other which adheres lightly to it but can be peeled off. The second film layer acts as the cover for the container, and the resin is poured between the two layers. The four sides of the container are made from the resin after photopolymerisation in strips of a few millimetres wide. The film to which the resin adheres and which forms the base of the container is of PVC or acrylonitrile PVC. It is placed on a sheet of glass and held in place by four spacers while the resin is poured on top of it. The covering layer is then placed over the resin and rolled to flatten it and expel any air bubbles.

Description

DESCRIPTION
La fabrication directe de tampons marqueurs au départ de résine liquide souple permet leur mise à disposition rapide et un meilleur prix de revient que celui des tampons marqueurs en caoulchouc.DESCRIPTION
The direct manufacture of marker pads from flexible liquid resin allows them to be made available quickly and at a better cost price than that of rubber marker pads.

Un inconvénient majeur réside dans l'emploi peu commode de la résilie Celle-ci, très poisseuse, est livrée en bidons d'où elle doit être versée entre 4 adhésifs de bordure -consitituanl un cadre sur un film spécial. A major drawback lies in the inconvenient use of the resilient This, very sticky, is delivered in cans from where it must be poured between 4 border adhesives -consitituanl a frame on a special film.

Recouverte ensuite d'un autre filin spécial, elle doit être répandue dans le cadre formé par les 4 adhésifs de bordure, saris bulle d'air. Ceci pour permettre une insolation correcte aux UV et la réalisation de bous tanipons. La seule énumération de ces opérations en montre la complexité, sans mettre en relief les difficultés matérielles dues au poisseux de la résine. Then covered with another special line, it must be spread in the frame formed by the 4 border adhesives, air bubble saris. This to allow a correct UV exposure and the realization of tanipon bous. The only enumeration of these operations shows their complexity, without highlighting the material difficulties due to the stickiness of the resin.

La présente invention supprime tous ces inconvénients. The present invention eliminates all of these drawbacks.

La résine liquide, destinée après photopolymérisation à donner directement des tampons marqueurs ou des clichés destinés aux prises d'empreinte, est coulée entre deux films transparents aux UV, de nature différente. Ils doivent permettre l'accrochage de la résine sur l'un des deux films , son adhérence sur l'autre afin quil soit pelable. The liquid resin, intended after photopolymerization to directly give marker stamps or plates intended for taking impressions, is cast between two films transparent to UV, of different nature. They must allow the adhesion of the resin on one of the two films, its adhesion on the other so that it is peelable.

Le lillll sur leqtiel adhére la résine constituera la base du
tampon marqucur s'il est en PVC, en PVC acrilonitryle s'il
constitue la base du cliché pour prise d'empreinte. The lillll on which adheres the resin will form the basis of the
rubber stamp if it is PVC, acrilonitryl PVC if
constitutes the basis of the snapshot for impression taking.

Le filrii de base (PVC ou PVC Acrilonitryle) est placé tendu sur uiie plaque de verre II y est maintenu par 4 cales doiit l'épaisseur varie eii fonction de l'épaisseur désirée pour le tampon ou le cliché. The base filrii (PVC or PVC Acrilonitryl) is placed stretched on a glass plate. It is held there by 4 wedges, the thickness of which varies and depends on the thickness desired for the stamp or plate.

La résilie souple pour le tampon, dure pour le cliché, est coulée sur le film, entre les cales, par un ensemble trémie / rouleau presseur qui nivelle la résine et chasse l'air / rouleau alimentateur qui assure la pose du filin constituant la couverture de la future boite
Les 4 côtés de la boite sont obtenus par la photopolymérisation sur chacun des côtés d'une bande de quelques Iiiilliiiiètres de large. Le reste de la résine est protégé par iiii cache , ltii permettant de rester liquide.The flexible resilient for the tampon, hard for the cliché, is cast on the film, between the shims, by a hopper / pressure roller assembly which levels the resin and expels the air / feed roller which ensures the laying of the rope constituting the cover from the future box
The 4 sides of the box are obtained by photopolymerization on each side of a strip a few Iiiilliiiiètres wide. The rest of the resin is protected by iiii cover, ltii allowing it to remain liquid.

La boite ainsi constituée est prête à l'emploi.  The box thus constituted is ready for use.
