Abstract

Machine for slitting a roll of fabric has a rotating shaft for holding the roll of material and a rotating knife, together with a mechanism for moving the roll at right angles to the knife. The rotating shaft is mounted in carriages which also house a rotating shaft with a pinion at each end which engages a fixed rack. The blade can be moved parallel to the axis of the roll to give a cut of any width. An electrical device automatically withdraws the blade from the shaft if the two come into contact. The cutting process is fully automated, and the quality of the cut is not dependent upon the skill of the operator.

Description

I.a présente iiiviit ioii concerne une machine pour le découpage de rouleaux de tissu.  I.a present iiiviit ioii relates to a machine for cutting fabric rolls.

On contact déjà des machines du type permettant d'obtenir des bandes de tissu de différentes longueurs. Toutefois, ces machines soit a commande ma- nuelle, c'est-à-dire qu'elles sont équipées d'une lame rotative qui est déplacée manuellement dans le sens transversal du rouleau de tissu prenant appui sur une barre rotative. We are already in contact with machines of the type enabling strips of fabric of different lengths to be obtained. However, these machines are manually operated, that is to say that they are equipped with a rotary blade which is moved manually in the transverse direction of the fabric roll bearing on a rotary bar.

La manipulation du rouleau exige une grande habileté car, si la lame rotative vient appuyer contre ce dernier avec une pression excessive, elle peut subir une surchauffe et, lorsqu'il s'agit de découper des matières synthétiques, elle risque également de faire fondre ces dernières. Handling the roller requires great skill because, if the rotating blade comes to press against it with excessive pressure, it can be overheated and, when cutting synthetic materials, it also risks melting these past.

En outre, dans des conditions semblables de pression excessive, le tissu a tendance à se relâcher, si bien que les niveaux de découpage des rouleaux ne sont plus uniformes avec, pour conséquence, une qualité médiocre du produit final, à savoir des bandes. In addition, under similar conditions of excessive pressure, the fabric tends to loosen, so that the cutting levels of the rollers are no longer uniform with the result that the quality of the final product, i.e. strips, is poor.

Un objet de la présente invention est de xé- soudre ce problème techni1ue en fournissant une machine permettant de découper des rouleaux de tissu d'une ma- nière entièrement automatique sans présenter les inconvénients précités et ce, de telle sorte que la lame rotative soit constamment maintenue à l'écart de l'opérateur. An object of the present invention is to solve this technical problem by providing a machine which makes it possible to cut rolls of fabric in a fully automatic manner without having the above-mentioned drawbacks, so that the rotary blade is constantly kept away from the operator.

La solution à ce problème est fournie par une machine destinée à découper des rouleaux de tissu, cette machine comprenant un arbre porte-rouleau et une lame rotative conçue pour découper le rouleau de tissu trans versaiement par rapport à son axe longitudinal, l'arbre porte-rouleau étant déplacé perpendiculairement à cette lame. En outre, la lame coupante rotative peut coulisser horizontalement et parallèlement à l'arbre porterouleau, si bien qu'elle peut être localisée dans des positions prédéterminées en fonction de la largeur des découpes successives. The solution to this problem is provided by a machine intended for cutting fabric rolls, this machine comprising a roller holder shaft and a rotary blade designed to cut the roll of fabric transversely relative to its longitudinal axis, the holder shaft -roll being moved perpendicular to this blade. In addition, the rotary cutting blade can slide horizontally and parallel to the roller shaft, so that it can be located in predetermined positions depending on the width of the successive cuts.

Enfin, selon une autre caractéristique de la présente invention, lorsque la lame entre en contact avec l'arbre porte-rouleau, un circuit électrique se ferme et vient alors s'engager sur un élément conçu pour éloigner l'arbre porte-rouleau de la lame. Finally, according to another characteristic of the present invention, when the blade comes into contact with the roller holder shaft, an electrical circuit closes and then engages on an element designed to move the roller holder shaft away from the blade.

D'autres objets et avantages de la machine de la présente invention apparaîtront à la lecture de la description ci-après donnée à titre d'exemple, mais sans aucun caractère limitatif, en se référant à l'unique dessin annexé qui est une vue en perspective de la machine suivant la présente invention. Other objects and advantages of the machine of the present invention will appear on reading the description below given by way of example, but without any limiting character, with reference to the single appended drawing which is a view in perspective of the machine according to the present invention.

La lame coupante 1 est entraînée en rotation par le groupe moteur à engrenages 2 fixé au porte-lame 3 qui peut coulisser horizontalement le long des guides 4 et 5 assujettis au bâti 6 de la machine. Ce mouvement horizontal est commandé par le moteur 7 solidarisé, à l'intervention d'une bôite de vitesses (non représentée), à une tige filetée 8, laquelle est à son tour reliée à une vis-mère 9 fixée au porte-lame 3. On prévoit également un programmateur 10 (dont on représente uniquement la roue perforée calée sur la même tige filetée 8) permettant de prérégler n'importe quel angle de rotation de la tige 8 qui correspond à son tour à un déplacement préréglé du porte-lame 3.Ainsi qu'on l'ex- pliquera ci-après, le rouleau de tissu supporté par l'arbre 11 et retenu-entre deux disques 12 et 13 se déplace horizontalement en direction de la lame rotative 1. The cutting blade 1 is rotated by the gear motor group 2 fixed to the blade holder 3 which can slide horizontally along the guides 4 and 5 secured to the frame 6 of the machine. This horizontal movement is controlled by the motor 7 secured, by means of a gearbox (not shown), to a threaded rod 8, which is in turn connected to a lead screw 9 fixed to the blade holder 3 There is also a programmer 10 (of which only the perforated wheel is shown wedged on the same threaded rod 8) making it possible to preset any angle of rotation of the rod 8 which in turn corresponds to a preset movement of the blade holder 3.As will be explained below, the roll of fabric supported by the shaft 11 and retained between two discs 12 and 13 moves horizontally in the direction of the rotary blade 1.

Le découpage du rouleau de tissu est ainsi effectué de manière programmée, étant donné que le programmateur 10 permet de localiser la laine 1 dans des positions fixes successives le long de la tige filetée 8, chacune de ces positions correspondant à des sections de rouleau de la largeur désirée. The cutting of the fabric roll is thus carried out in a programmed manner, since the programmer 10 makes it possible to locate the wool 1 in successive fixed positions along the threaded rod 8, each of these positions corresponding to roll sections of the desired width.

Comme le montre le dessin, on prévoit égale- ment deux moteurs 14 et 15 associés à des régulateurs de vitesse qui règlellt respectivement la rotation de l'arbre lî et celle de l'arbre 1(). Cet arbre 16 qui passe à travers deux plaques latérales 17 et 18, comporte, à ses extrémités, deux pignons 19, le dessin illustrant uniquement le pignon de droite qui vient s'en- gager dan une crémaillère 20 fixée au côté 21 du bâti 6. As shown in the drawing, two motors 14 and 15 are also provided, associated with speed regulators which regulate respectively the rotation of the shaft 1 and that of the shaft 1 (). This shaft 16 which passes through two side plates 17 and 18, comprises, at its ends, two pinions 19, the drawing illustrating only the right pinion which comes to engage in a rack 20 fixed to the side 21 of the frame 6 .

Chacune des deux plaques latérales 17 et 18 supporte deux galets 22 glissant sur une barre fixe 23, ainsi qu'un support 24 glissant sur une barre fixe 25. Each of the two side plates 17 and 18 supports two rollers 22 sliding on a fixed bar 23, as well as a support 24 sliding on a fixed bar 25.

Sur l'autre côté 26 du bâti, est fixée la crémaillère 27 dans laquelle vient s'engager l'autre pignon (non représenté) calé sur l'arbre 16.On the other side 26 of the frame, the rack 27 is fixed in which the other pinion (not shown) engages wedged on the shaft 16.

Avec la machine décrite ci-dessus, lorsque l'arbre lb est entraîné en rotation vers la droite, les deux pignons tournent respectivement sur les crémaillères 20 et 27, ce qui a pour effet de déplacer les deux plaques 17 et 18 et, partant, l'arbre ll en direction de la lame 1 qui tourne sur son axe fixe si bien que, si cette dernière entre en contact avec l'arbre 11, le circuit électrique prévu alimenté par la source S se ferme entre cet arbre ll et le guide 4, tandis que les contacts du relais R de ce circuit passent de la position illustrée en trait plein à la position illustrée en traits discontinus; en conséquence, le circuit S' alimentant le moteur 15 change de polarité et le sens de rotation de ce dernier est alors inversé, faisant ainsi tourner les pignons 19 dans la direction inverse avec, pour résultat, un déplacement immédiat de l'arbre porte-rouleau Il à
l'écart de la lame 1 qui, des lors, ne risque pas d'être
endommagée . With the machine described above, when the shaft 1b is rotated to the right, the two pinions rotate respectively on the racks 20 and 27, which has the effect of displacing the two plates 17 and 18 and, consequently, the shaft ll in the direction of the blade 1 which rotates on its fixed axis so that, if the latter comes into contact with the shaft 11, the electrical circuit provided supplied by the source S closes between this shaft ll and the guide 4, while the contacts of the relay R of this circuit pass from the position illustrated in solid lines to the position illustrated in broken lines; Consequently, the circuit S 'supplying the motor 15 changes polarity and the direction of rotation of the latter is then reversed, thereby rotating the pinions 19 in the opposite direction with, as a result, an immediate displacement of the carrier shaft. roll it to
the gap of the blade 1 which, therefore, is not likely to be
damaged.
