Title (EN) WEB UNWINDING AND SPLICING APPARATUS
(FR) APPAREIL DE DEVIDAGE ET D'EPISSAGE DE BANDES
Abstract: front page image
(EN)A web unwinding and splicing apparatus (10) includes two carts (14a, 14b) each supporting a plurality of web rolls (28a-e, 29a-e), along with a first and second drive mechanism (60, 62) for selectively moving either cart (14a, 14b). The carts (14a, 14b) are alternately advanced by a controller (90) as web rolls (28a-e, 29a-e) carried by the carts (14a, 14b) are alternately depleted. The apparatus (10) provides continuous unwinding for relatively long periods of time without operator attention.
(FR)Cette invention concerne un appareil de dévidage et d'épissage (10) de bandes, lequel comporte deux chariots (14a, 14b) portant chacun plusieurs rouleaux de bandes (28a-e, 29a-e), ainsi qu'un premier et un second mécanismes d'entraînement (60, 62) permettant de déplacer sélectivement l'un ou l'autre chariot (14a, 14b). Ces chariots (14a, 14b) sont avancés en alternance à l'aide d'une unité de commande (90), à mesure que les rouleaux de bandes (28a-e, 29a-e) portés par lesdits chariots (14a, 14b) se dévident alternativement. Cet appareil (10) permet d'obtenir un dévidage continu pendant des durées relativement longues et sans que l'opérateur ne soit obligé d'y prêter attention.
