Abstract

The blanket securing grip for the cylinder of a printing machine uses a clip made of a metal such as aluminium and which is approximately V shaped in cross section. The interior surface of each arm carries a pattern of small teeth (3) alternating with larger teeth (4). These grip the end (5) of the blanket (5) when forced together. One arm (2) carries a flange (6) turned outwards at its top and the other (1) carries a smaller flange (7) turned outwards in the opposite direction at the bottom, for attachment to the printing cylinder.

Description

Le brevet principal concerne un dispositif d'accrochage des blanchets d'impression sur les cylindres à gorge des rotatives offset suivant lequel une réglette formant surépaisseur face caoutchouc du blanchet est fixée le long de chaque extrémité d'accrochage de ce dernier. Les extrémités ainsi renforcées du blanchet sont introduites de façon connue dans la rainure du cylindre de presse et serrées par une barre de pression. The main patent relates to a device for hanging printing blankets on the cylinders with throats of offset presses, according to which a strip forming an extra thickness rubber face of the blanket is fixed along each hooking end of the latter. The reinforced ends of the blanket are introduced in a known manner into the groove of the press cylinder and clamped by a pressure bar.

Ces réglettes sont généralement obtenues par repli sur elle-même d'une bande d'aluminium enserrant le blanchet sur lequel elles sont fixées par oeillets ou par sertissage et elles présentent sur un bord d'un côté une aile de butée et sur l-'au- tre caté une nervure pour faciliter l'introduction et le retrait de l'habillage du blanchet. These strips are generally obtained by folding over itself an aluminum strip enclosing the blanket on which they are fixed by eyelets or by crimping and they have on an edge on one side a stop wing and on the also a rib to facilitate the insertion and removal of the coating of the blanket.

La présente addition a pour objet une réglette perfectionnée pour réaliser l'habillage du blanchet d'une fabrication plus rapide et plus économique. The present addition relates to an improved strip for carrying out the coating of the blanket of a faster and more economical manufacture.

Cette réglette est obtenue par repli sur elle-même et par moitié et sertissage d'une bande d'aluminium à profil en V, dont les faces en regard sont crantées et qui présente d'un côté un bord inférieur prolongé par une aile en retour d'équerre formant talon et de l'autre côté un bord supérieur muni d'une nervure de butée. This strip is obtained by folding in on itself and in half and crimping a strip of aluminum with a V-profile, the opposite faces of which are notched and which has on one side a lower edge extended by a wing in return. square forming heel and on the other side an upper edge provided with a stop rib.

Grâce à ce talon et cette butée et à l'absence de moyens de fixation du blanchet dans la réglette de pincement, il est facile d'introduire et de retirer un tel habillage de blanchet de la gorge de la rotative offset d'imprimerie. Thanks to this heel and this stop and to the absence of means for fixing the blanket in the pinch strip, it is easy to introduce and remove such a blanket covering from the throat of the printing offset press.

On a représenté, vue en bout, au dessin, une réglette suivant l'invention, avant sertissage à la figure 1 et après sertissage à la figure 2. There is shown, seen in end, in the drawing, a strip according to the invention, before crimping in Figure 1 and after crimping in Figure 2.

Cette réglette, réalisée en métal tel que l'aluminium, a un profil en V. Les faces de même hauteur et en regard 1, 2 de la réglette sont usinées pour présenter des griffes ou crans 3 et des dents 4 destinées à pénétrer le blanchet 5 introduit entre elles (fig. 1). This strip, made of metal such as aluminum, has a V-shaped profile. The faces of the same height and facing 1, 2 of the strip are machined to present claws or notches 3 and teeth 4 intended to penetrate the blanket. 5 inserted between them (fig. 1).

Le bord libre d'une des faces 2 de la réglette présente une aile 6 en retour d'équerre vers l'extérieur, formant talon, tandis que le bord inférieur de la face 1 présente une nervure externe de butée 7 ; ce talon et cette butée permettent l'intro duction et le retrait facile du blanchet dans le cylindre d'lmprimerie.  The free edge of one of the faces 2 of the strip has a wing 6 in return towards the outside towards the outside, forming a heel, while the lower edge of the face 1 has an external stop rib 7; this heel and this stop allow the intro duction and the easy removal of the blanket in the printing cylinder.

Aucun moyen de fixation du blanchet 5 dans sa réglette d'habillage ne freine ce positionnement, le blanchet étant fortement maintenu en place par les griffes 3 et dents 4 de la réglette dont les flancs ont été refermés sur eux-mêmes à la presse (figure 2)  No means of fixing the blanket 5 in its covering strip prevents this positioning, the blanket being strongly held in place by the claws 3 and teeth 4 of the strip whose sides have been closed on themselves with the press (FIG. 2)
