Title
(EN) DEVICE FOR TRANSVERSELY EXTENDING A BELT-LIKE BODY
(FR) DISPOSITIF SERVANT A ETENDRE TRANSVERSALEMENT UN CORPS EN FORME DE BANDE
Abstract
(EN)
A transversely extending device comprises a pair of pulleys substantially disposed in an identical plane and adapted to rotate in opposite directions and a pair of belts set over the pair of pulleys, respectively. By transferring a belt-like body such that it expands in a flare shape while being held on side edge portions thereof by the pulleys and belts, a belt-like body is transversely extended. At least a pair of pressing rolls are provided inclined against the belts for pressing to the respective belts the side edge portions of the belt-like body before they are held between the respective pulleys and belts. With this construction, the transversely extending device for effectively preventing the disengagement of the belt-like body is thus realized.
(FR)
L'invention concerne un dispositif d'extension transversale, comprenant une paire de poulies placées sensiblement dans le même plan et conçues pour tourner dans des sens opposés, ainsi que deux courroies placées chacune sur une de ces poulies. Un corps en form de bande est étendu transversalement par le fait qu'il est transféré de façon qu'il s'étende sous une forme évasée tout en étant maintenu, sur ses bords latéraux, par lesdites poulies et lesdites courroies. Au moins une paire de rouleaux d'appui sont montés inclinés contre les courroies, cela pour appliquer chacun des bords latéraux du corps en forme de bande sur sa courroie respective, cela avant qu'il soit maintenu entre sa poulie et sa courroie respectives. Grâce à cet agencement, on obtient un dispositif d'extension transversale qui empêche efficacement la sortie du corps en forme de bande.
