Abstract

The container has one rigid wall made from a film material such as PVC or acrylonitrile PVC, to which the photopolymerisable resin will adhere, and a covering layer of a supple film, such as polyester, polycarbonate or methacrylate, which will not adhere to the resin. In a variant the rigid wall can be of polyester, polycarbonate or methacrylate, and the cover of supple PVC or acrylonitrile PVC. The container walls are thermally welded together three sides, and after one required amount of resin has been injected the container is subjected to a vacuum and the fourth side welded.

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 caoutchouc.DESCRIPTION
The direct manufacturing of marker pads from flexible liquid resin allows their rapid provision and a better cost price than that of rubber marker pads.

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

Recouverte ensuite d'un autre film spécial, elle doit être répandue dans le cadre formé par les 4 adhésifs de bordure, sans bulle d'air. Ceci pour permettre une insolation correcte aux UV et la réalisation de bons tampons. 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 film, it must be spread in the frame formed by the 4 border adhesives, without air bubbles. This to allow correct UV exposure and the production of good pads. 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 destinée après photopolymérisation à donner directement les tampons marqueurs, ou le cliché pour prise d'empreinte, est injectée entre deux films transparents aux UV, mais de nature et de rigidité différentes, et soudés entre eux sur 3 côtés, l'un des films pouvant être un PVC ou un PVC acrilonitryle sur lequel adhère la résine, l'autre film pouvant être un polyester, ou un polycarbonate, ou un métacrylate, souple ou rigide, sur lequel la résine ne doit pas adhérer. The resin intended after photopolymerization to directly give the marking pads, or the cliché for impression taking, is injected between two films transparent to UV, but of different nature and rigidity, and welded together on 3 sides, one of the films which may be a PVC or an acrilonitryl PVC on which the resin adheres, the other film may be a polyester, or a polycarbonate, or a metacrylate, flexible or rigid, on which the resin must not adhere.

Le film rigide constitue le fond de la boite, le film souple son couvercle.  The rigid film constitutes the bottom of the box, the flexible film its cover.

Le volume de résine correspondant à l'épaisseur nécessaire pour obtenir le relief désiré est injecté entre les deux films ; on fait ensuite le vide pour enlever l'air qui gênerait la définition des timbres ou des clichés, et on soude la 4e paroi. The volume of resin corresponding to the thickness necessary to obtain the desired relief is injected between the two films; we then create a vacuum to remove the air that would interfere with the definition of stamps or shots, and we weld the 4th wall.

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

Le négatif à reproduire est posé, entre les cales, sur une plaque de verre portant de chaque côté une cale de l'épaisseur correspondant à celle du cliché ou des timbres pour lesquels la quantité voulue de résine a été injectée. The negative to be reproduced is placed, between the shims, on a glass plate carrying on each side a shim of the thickness corresponding to that of the plate or stamps for which the desired quantity of resin has been injected.

On recouvre le négatif par la boite de résine et on pose par dessus l'ensemble une deuxième plaque de verre maintenue serrée contre les cales par des pinces ou par un système à charnières et vis. The negative is covered with the resin box and a second glass plate is held over the whole, held tight against the wedges by clamps or by a hinge and screw system.

La boite est insolée aux UV selon le même principe que celui employé pour les autres types de résines photopolymérisables  The box is UV-exposed according to the same principle as that used for other types of photopolymerizable resins
