Abstract

After opening a pivoting cover (4) an inserting a roll of paper (1), the paper is unrolled until a portion of it made to emerge through an opening in the upper wall (10), the cover (4) is closed again, thus retaining the paper at the output of a printer roller and between the free end edge (11) of the cover and the opposite opening edge (12), the emerging portion of paper is pulled, it is folded back and its cutting against the free end edge (11) is caused. The paper is rewound to bring the cut end of the strip to the downstream output of the printer roller (2) and then the paper is made to unwind in order to push the strip back until its cut free end penetrates into the paper cutter (6).

Description

1 - La présente invention a pour objet un procédé de mise en place1 - The subject of the present invention is a method of setting up

automatique du papier dans le coupe-papier d'une machine imprimante du type comportant, en amont du coupe-papier, un rouleau alimentaire de papier, un rouleau imprimeur et une tête d'impression coopérant avec le rouleau imprimeur et portée par un capot pivotant obturant une ouverture ménagée dans la paroi supérieure de la machine et donnant accès au rouleau alimentaire et au rouleau imprimeur lorsque le capot est soulevé. La mise en place manuelle du papier dans le coupe-papier de ce type de machines est une opération délicate, qui prend souvent plus de temps que prévu et dont le résultat est parfois défectueux, du fait notamment du mauvais état de l'extrémité de la bande de papier que  automatic paper in the paper cutter of a printing machine of the type comprising, upstream of the paper cutter, a paper feed roller, a printing roller and a printing head cooperating with the printing roller and carried by a pivoting cover closing an opening in the upper wall of the machine and giving access to the food roller and the printing roller when the cover is raised. The manual placement of paper in the paper cutter of this type of machine is a delicate operation, which often takes more time than expected and whose result is sometimes defective, due in particular to the poor condition of the end of the strip of paper that

l'on doit introduire dans le coupe-papier.  it must be inserted into the paper cutter.

L'invention vise à remédier à ces inconvénients, et elle prévoit, à cet effet, un procédé de mise en place du papier dans le coupe-papier selon lequel, après ouverture du capot pivotant et mise en place du rouleau alimentaire de papier dans son logement, on déroule le papier du rouleau jusqu'à en faire sortir une partie par l'ouverture de paroi supérieure, on referme le capot retenant ainsi le papier à la sortie du rouleau imprimeur et entre le bord d'extrémité libre du capot et le bord d'ouverture opposée, on tire la partie de papier sortie de l'ouverture pour la rabattre contre le capot et provoquer sa découpure contre son bord d'extrémité  The invention aims to remedy these drawbacks, and it provides, to this end, a method of placing paper in the paper cutter according to which, after opening the pivoting cover and placing the food roll of paper in its housing, unroll the paper from the roll until part of it comes out through the upper wall opening, close the cover thus retaining the paper at the exit of the printing roller and between the free end edge of the cover and the opposite opening edge, pull the part of the paper out of the opening to fold it against the cover and cut it against its end edge

On voit que le procédé de l'invention assure une mise en place automatique du papier dans le coupe-papier, l'intervention manuelle étant limitée, en dehors de la pose du rouleau alimentaire de papier dans son logement, à la coupe d'une portion de bande sur le bord d'extrémité libre du capot Du fait de cette coupe d'extrémité de bande, on est assuré du parfait état de cette extrémité, facilitant évidemment son introduction  paper. It can be seen that the method of the invention ensures automatic positioning of the paper in the paper cutter, manual intervention being limited, apart from laying the paper food roll in its housing, to cutting a strip portion on the free end edge of the cover Because of this strip end cut, we are assured of the perfect condition of this end, obviously facilitating its introduction

De part et d'autre du rouleau imprimeur 2, sont prévus des éléments de guidage de la bande de papier C Entre le rouleau de papier 1 et le rouleau imprimeur 2, -3 - l'élément de guidage est constitué par une goulotte 13 qui fait face à la tête d'impression 3 et, de l'autre côté du rouleau 2, l'élément de guidage est formé par  On either side of the printing roller 2, elements for guiding the paper strip C are provided. Between the paper roller 1 and the printing roller 2, -3 - the guide element is constituted by a chute 13 which faces the print head 3 and, on the other side of the roller 2, the guide element is formed by

une plaque 14 et un téton 15 porté par le capot 4.  a plate 14 and a stud 15 carried by the cover 4.
