Abstract

L'invention concerne un appareil de rétention de tissu et un procédé destiné à empêcher le bord d'un tissu coupé de bouger ou de se replier lors des manipulations ultérieures avec ce tissu. L'invention utilise de préférence une ouverture à vide qui aspire et retient une partie (p.ex., le bord) d'un tissu coupé. L'ouverture à vide est reliée à un appareil de mise sous vide qui crée une force de succion qui aspire la partie de tissu dans l'ouverture à vide et la retient dans celle-ci. Pour cette raison l'ouverture se présente de préférence comme une rainure ou une fente allongée située près de l'endroit où l'on coupe le tissu, ce qui permet à la partie de tissu de rester près de l'ouverture à vide et d'être aspirée dans celle-ci. L'ouverture peut comprendre une gorge définie par une ou plusieurs parois qui s'étendent en dessous de la surface dans laquelle a été pratiquée l'ouverture. La présente invention peut notamment s'utiliser avec un cylindre de coupe dans lequel une ou plusieurs lames de coupe sont montées sur une surface de cylindre de coupe. Dans ce système, l'ouverture à vide est située le long de la lame de coupe, derrière celle-ci, et aspire (par la force de succion qui s'exerce à travers l'ouverture à vide) la partie du tissu coupé dans l'ouverture à vide après que le tissu à été coupé par la lame de coupe. Dans d'autres modes de réalisation de l'invention, l'ouverture à vide peut se situer devant la lame de coupe afin de fixer la partie du tissu coupé qui se trouve devant la lame de coupe. Le cas échéant, une ouverture à vide peut même se situer des deux côtés de la lame de coupe.
