CA 2320855

The rewinding machine comprises: an insertion device (11) for sequentially inserting winding spindles (M) into a winding area; winding means (1, 3, 5) in said winding area, which wind predetermined quantities of web material onto said spindles; an extractor (25) downstream of the winding area for extracting said spindles from the rolls of web material formed on them; and a recirculation path (71) for returning the spindles extracted from said rolls toward said insertion device. The spindles are made in two portions which can be connected and disconnected; the extractor extracts each of said two portions from a corresponding end of the corresponding wound roll. Means are also provided for reconnecting said two portions to each other so that said spindles can be reinserted into said winding area.

L'invention concerne un réenrouleur comportant: un dispositif d'introduction (11) destiné à l'introduction par séquences de broches d'enroulement (M) dans une zone d'enroulement; un dispositif d'enroulement (1, 3, 5) situé dans cette zone d'enroulement et enroulant une quantité prédéterminée de bande sur les broches; un dispositif d'extraction (25) destiné à extraire les broches des rouleaux de bande formés autour d'elles; et une trajectoire de recirculation (71) destinée à renvoyer les broches extraites des rouleaux vers le dispositif d'introduction. Les broches sont formées de deux parties pouvant être connectées et déconnectées. Le dispositif d'extraction extrait chaque partie d'une extrémité correspondante du rouleau enroulé correspondant. L'invention concerne également un dispositif de reconnexion des deux parties de sorte que les broches puissent être réintroduites dans la zone d'enroulement.
