Abstract

Les différentes forces de traction dans la bande sont obtenues du fait qu'un rouleau flottant est placé avant la tête et qu'un rouleau flottant est placé également après la tête; la bande est guidée sur ces deux rouleaux dont les poids diffèrent, tandis que le dispositif de freinage est placé entre le rouleau flottant le moins lourd et la tête. Lorsque le dispositif de freinage est opérant, le rouleau le plus lourd agit librement sur le porteur d'information cependant que le rouleau le moins lourd fait dévider du rouleau de réserve une certaine longueur de bande par suite du déplacement inévitable dudit rouleau. Lorsque le dispositif de freinage est inopérant, le rouleau le plus lourd est arrêté, alors que le rouleau le moins lourd agit librement sur le porteur qu'il ramène ainsi dans sa position de départ. Application aux imprimantes rapides.The different tensile forces in the web are obtained by the fact that a floating roller is placed before the head and a floating roller is also placed after the head; the web is guided on these two rollers, the weights of which differ, while the braking device is placed between the lighter floating roller and the head. When the braking device is operating, the heavier roll acts freely on the information carrier, while the lighter roll unwinds a certain length of tape from the reserve roll as a result of the inevitable movement of said roll. When the braking device is inoperative, the heaviest roller is stopped, while the lighter roller acts freely on the carrier, which it thus returns to its starting position. Application to fast printers.
