A two-drum belt winder includes a belt looped over two fixedly mounted support drums. The tension in the belt is adjustable from an initially relieved tension condition where a depression is formed in the belt over the notch between the support drums. A new core is inserted in the depression and is wrapped by the on-coming paper web to begin forming a wound roll of paper. As the wound roll of paper increases in diameter, the tension in the looped belt is increased to provide greater support in the span between the nips of the wound roll over the belt against the support drums. Initially, a rider roll is also brought into nipping engagement with the wound paper roll. The nip load of the rider roll is gradually relieved as the diameter of the wound paper roll increases. Eventually, the rider roll is relieved except for a nominal pressure contact with the wound paper roll so that the tension of the on-coming paper web being wound into the wound roll in the nips on the support drums is essentially due to the weight of the wound roll. The wound roll is continuously supported symmetrically over a segment of its lower peripheral surface by a span of the tensioned belt and the nips of the horizontally disposed support drums.

ne bobineuse à courroie et à deux tambours comprend une courroie enroulée autour de deux tambours supports montés de façon fixe. La tension dans la courroie est réglable à partir d'un état de tension initialement relâchée alors qu'une dépression est formée dans la courroie au-dessus de l'espace entre les tambours supports. Un nouveau mandrin est inséré dans la dépression et est enveloppé par la feuille continue de papier qui arrive pour commencer à former une bobine de papier. ~ mesure que la bobine de papier augmente de diamètre, la tension dans la courroie enroulée est augmentée pour assurer un meilleur support dans l'espace entre les zones de contact de la bobine au-dessus de la courroie contre les tambours d'appui. Initialement, un rouleau presseur est également mis en contact avec la bobine de papier. La charge de contact du rouleau presseur est graduellement relâchée à mesure que le diamètre de la bobine de papier augmente. Éventuellement, le rouleau presseur n'exerce plus qu'une pression minimale sur la bobine de papier de sorte que la tension de la feuille continue de papier qui s'enroule sur la bobine dans les zones de contact contre les tambours supports est essentiellement due au poids de la bobine. La bobine de papier est constamment supportée symétriquement sur un segment de sa surface périphérique inférieure par une partie de la courroie tendue et par les zones de contact des tambours supports disposés horizontalement.
