Guidage de cylindres à glissement
La présente invention concerne une constitution particulière de mécanismes étireurs dans lesquels une ou plusieurs paires de cylindres de pression sont automatique- ment guidées parallèlement aux cylindres inférieurs au moyen d'un bras de direction à articulation située à l'arrière, et l'axe d'une des paires de cylindres est fixe. tandis que celui de l'autre paire de cylindres est disposé de façon à pouvoir pivoter autour de l'axe du bras de direction.
L'invention concerne en particulier la disposition des pièces de guidage pour les cylindres à glissement. Tan- dis qu'habituellement les cylindres à glissement sont guidés sur la tige de retenue des cylindres de pression, on a choi-
<Desc/Clms Page number 2>
si, suivant la présente invention, une place particuliè- rement favorable pour la disposition de ces pièces de tel- le façon qu'il est maintenant possible en cas d'emploi du bras de direction de supprimer complètement la tige de re- tenue, nécessaire jusqu'à présent, des cylindres de pres- sion. On emploie maintenant en effet la barre de changement pour les courroies du mécanisme d'étirage comme support pour les pièces de guidage des cylindres à glissement.
Un exemple de réalisation de l'invention est représenté au dessin.
La fig. 1 montre une vue de côté, en partie en coupe, des pièces principales d'un mécanisme étireur à courroies, comportant deux paires de cylindres.
La fig. 2 est une vue d'un détail de la fig. l, en vue de dessus.
Suivant la présente invention les cylindres à glissement 67 sont maintenus par des pièces de guidage 65 qui sont vissées, de façon permettant le déplacement, sur une pièce en équerre 66 qui embrasse la barre de change- ment 64 pour les courroies du mécanisme étireur.
Les tourillons du cylindre à glissement 67 se meuvent dans ces pièces de guidage 65. Les pièces de gui- dage elles-mêmes sont chaque fois disposées en-dessous du bras de direction 1 guidant les cylindres supérieurs 8,8' e sont ouvertes du haut de telle façon qu'après soulèvement du bras de direction,les cylindres ' glissement peuvent êtr facilement enlevés et mis en place.
Le prolongement, dirigé vers l'avant, de la piè- ce de guidage 65 forme un point d'appui pour le support 23, placé au-dessus de lui, du cylindre supérieur 8, pour le ca où la paire de cylindres supérieurs 8,8' est retirée des supports 23,24 et qu'un déchargement particulier du bras de direction n'est pas effectué.

Sliding cylinder guide
The present invention relates to a particular constitution of stretching mechanisms in which one or more pairs of pressure cylinders are automatically guided parallel to the lower cylinders by means of a steering arm with articulation located at the rear, and the axis d. one of the pairs of cylinders is fixed. while that of the other pair of cylinders is arranged so as to be able to pivot about the axis of the steering arm.
The invention relates in particular to the arrangement of the guide parts for the sliding cylinders. While usually the sliding cylinders are guided on the retaining rod of the pressure cylinders, it has been chosen
<Desc / Clms Page number 2>
if, according to the present invention, a particularly favorable place for the arrangement of these parts in such a way that it is now possible, when using the steering arm, to completely eliminate the retaining rod, necessary so far, pressure cylinders. The change bar for the belts of the stretching mechanism is now used as a support for the guide parts of the sliding rollers.
An exemplary embodiment of the invention is shown in the drawing.
Fig. 1 shows a side view, partly in section, of the main parts of a belt stretching mechanism, comprising two pairs of cylinders.
Fig. 2 is a view of a detail of FIG. l, in top view.
In accordance with the present invention, the slide rollers 67 are held by guide pieces 65 which are screwed, so as to allow movement, to an angled piece 66 which embraces the change bar 64 for the straps of the stretching mechanism.
The journals of the sliding cylinder 67 move in these guide pieces 65. The guide pieces themselves are each time arranged below the steering arm 1 guiding the upper cylinders 8,8 'e are open from above so that after lifting of the steering arm, the sliding cylinders can be easily removed and fitted.
The extension, directed towards the front, of the guide piece 65 forms a fulcrum for the support 23, placed above it, of the upper cylinder 8, for the case where the pair of upper cylinders 8 , 8 'is removed from the supports 23, 24 and a particular unloading of the steering arm is not carried out.
