    摘要: Une bobineuse sert à enrouler et/ou à dévider des feuillards métalliques avec une force de traction comprise entre 10 kN et 1000 kN. La bobineuse comprend un tambour expansible d'enroulement (1) porté par un arbre creux (2) monté sur un support (3) et traversé par une tige d'entraînement (5) qui sert à actionner le tambour expansible d'enroulement (1). La tige d'entraînement (5) est formée par la tige de piston d'un cylindre de réglage (4) agencé sur l'extrémité de l'arbre creux (2) opposée au tambour d'enroulement (1). Afin de réduire le moment d'inertie de masse de la bobineuse, afin d'éviter un jeu dans l'entraînement et de simplifier la structure de la bobineuse, l'entraînement de la bobineuse comprend un moteur agencé dans le support (3), entre les paliers (10, 11) de l'arbre creux (2), et dont le rotor (13) est monté sur l'arbre creux (2).

    摘要: Es wird eine Bundsammelstation für Drahtwalzstrassen mit einer Bundbildekammer, die aus Vorsammler, Sammeldorn und Begrenzungskorb besteht beschrieben, bei der wenigstens zwei Sammeldorne mittels Schwenkbewegung wechselseitig in eine Beladestellung und/oder Entlade­stellung bringbar sind. Der Umhüllungdurchmesser des Sammeldorns in der Beladestellung ist gegenüber seinem Durchmesser in seiner Entladestellung für ein aufgewickeltes Drahtbund veränderbar. Hierfür besteht der Sammeldorn aus einer Mehrzahl von Dornstangen, von denen einige festehend angebracht und die übrigen gegen­über den feststehenden radial beweglich gelagert sind.

    摘要: The present invention relates to a rolling mill (1) comprising:
    - a rolling stand (2) comprising at least two rolls (3) between which a strip (N) to be rolled is made to pass;
    - at least one reel (4A, 4B) comprising a mandrel (10) for winding and/or unwinding said strip (N) during the rolling operations, wherein said mandrel (10) comprises a clamping system (20) associated with a slot (11) of the mandrel (10) for clamping one end of the strip (N) in said slot (11) during a step of winding the strip (N) on the mandrel (10).
    The invention is characterized in that the clamping system (20) comprises at least one grip (20A) forming a clamp together with an inner wall (11A) of said slot (11), said at least one grip (20A) being coupled to a closed hydraulic circuit (21, 22, 23, 24) of the clamping system (20), which allows said at least one grip (20A) to translate relative to the wall (11A), so as to switch from a first open position, wherein the strip (N) can be inserted into said slot (11), to a second closed position, wherein the strip (N) can be clamped in said slot (11), and vice versa.
