<Desc/Clms Page number 1>
ou ruban
La présente invention @ bande/de manoeuvre pour fermetures (en particulier volets.,+ persiennes,etc). en- roulables recouvert de matière thermoplastique.
On sait que les rubans ou bandea employées jusqu'à présent pour la fermeture et l'ouverture des fermetures enrou- lables s'usent facielement à cause du frottement qu'elles su- bissent dans les fentes par lesquelles elles sont introduites dans les dispositifs d'enroulement et dans les dispositifs de blocage de ces bandes dans la position voulue.
<Desc/Clms Page number 2>
On sait également que le plus grand frottement et par conséquent la plus grande usure à laquelle les bandes précitées sont soumises s'exerce sur les bords longitudinaux, de sorte que les fils'de la chaîne et de la trame- en ces points se rom- pent facilement et causent peu à peu la rupture des fils succes- sifs jusqu'à la rupture complète de la bande, rupture qui se produit, évidemment, de manière imprévue et telle que, dans cer- taines conditions, elle peut même provoquer des accidents aux personnes.
Le but de la présente invention est d'obvier à cet inconvénient en réalisant une bande de manoeuvre pour fermetures enroulables, constituée d'une matière thermoplastique armée longitudinalement d'une matière relativement rigide.
L'invention va être décrite plus en détail ci-après avec référence à la planche'de dessins ci-annexée, dont : la figure 1 représente un tronçon de la bande ou ru- ban vu en plan, et la figure 2 représente une coupe transversale de la même bande.
Dans ces figures,l désigne la bande-de matière thermo- plastique;2 et 3 désignent des éléments filiformes flexibles de matière relativement rigide d'armature, noyés dans ladite matière thermoplastique. Les fils longitudinaux latéraux 3 ont une plus grande section que les fils 2, de manière à obtenir les. bords longitudinaux 4 et 5..de la bande, légèrement épaissis, afin d'offrir une surface de contact plus grande et par consé- quent plus résistante aux points où s'exerce le plus grand frottement.
Avec la bande réalisée selon la présente invention, on obtient, autre l'avantage susmentionné, que le frottement soit notablement réduit, parce que la-matière thermoplastique de cou- verture présente une surface de .contact un peu plus glissante .
Up autre avantage de la bande réalisée selon la présen- te invention est dû au fait que ladite bande peut être lavée et
<Desc/Clms Page number 3>
est par conséquent très intéressante au point de vue de l'hy- giène.

or ribbon
The present invention @ band / operating for closures (in particular shutters., + Shutters, etc.). Rollers covered with thermoplastic material.
It is known that the ribbons or bandea used until now for the closing and opening of the roll-up closures wear out easily because of the friction which they suffer in the slits through which they are introduced into the devices of. winding and in the locking devices of these bands in the desired position.
<Desc / Clms Page number 2>
It is also known that the greatest friction and therefore the greatest wear to which the aforementioned bands are subjected is exerted on the longitudinal edges, so that the threads of the warp and weft at these points break. easily and gradually cause the breakage of the successive threads until the complete breakage of the strip, a breakage which occurs, of course, in an unforeseen manner and such that, under certain conditions, it can even cause accidents to people.
The object of the present invention is to obviate this drawback by producing an operating strip for roll-up closures, made of a thermoplastic material reinforced longitudinally with a relatively rigid material.
The invention will be described in more detail below with reference to the attached drawing board, of which: FIG. 1 represents a section of the strip or strip seen in plan, and FIG. 2 represents a section. transverse of the same strip.
In these figures, 1 denotes the strip of thermoplastic material, 2 and 3 denote flexible filiform elements of relatively rigid reinforcing material, embedded in said thermoplastic material. The lateral longitudinal son 3 have a larger section than the son 2, so as to obtain them. longitudinal edges 4 and 5 of the strip, slightly thickened, in order to offer a larger contact surface and consequently more resistant at the points where the greatest friction is exerted.
With the strip made according to the present invention, a further advantage is obtained that the friction is significantly reduced, because the thermoplastic covering material has a slightly more slippery contact surface.
Another advantage of the strip produced according to the present invention is due to the fact that said strip can be washed and
<Desc / Clms Page number 3>
is therefore very interesting from a hygienic point of view.
