English to French Tech/Engineering Engineering: Industrial corrugator (splicer )

Bonjour,

Connaissez-vous l'équivalent français de "capstan roll", dans le contexte suivant ? (Onduleuse)

One cause of fractures can be too much tension on the medium.

As the roll runs out, it obviously gets smaller and has less mass. A smaller roll will require less brake to maintain the same paper tension as it did when it was full. Therefore it is important to reduce the brake progressively as the roll runs out. Modern splicers in good working order will do this automatically. If the web tension control is not functioning properly, it will be necessary to make these adjustments manually until the unit is repaired.
A driven capstan roll helps alleviate this problem as it will
turn slightly faster than paper speed to reduce excessive
tension and friction as the paper goes over the heated vessel
(the pre-conditioner in this case).

Merci d'avance et bon weekend à tous ceux qui liront ce message !
