Embodiment Construction

[0031][31] FIG. 1 shows the whole of a winding device, for example of the type described in the above-mentioned document US-A-2,918,226, and which thus comprises a winding drum 2, which 2. The outlet of a roller shaker T is in a groove F, and the metal belt 1 driven by a compaction-deflector device travels on the roller shaker T. The compaction-deflector device includes a deflector roller D and a pressure roller R, the belt body is deflected downward on the deflecting roller D, so as to be guided to the reel 2, and wound on the reel 2, so that the belt body is driven by friction, and the Said pinch roller R is driven in rotation at a speed slightly lower than that of the reel in order to hold the strip 1 , which is thus under tension so as to be wound in a loop tightly wound on the reel 2 .

[0032] [32] The strip 1 is pressed against the reel 2 in a known manner by means of a roller 3 which exerts a thrust along a radial plane Q, wherein the shaft 21 of the reel 2 and the rol...

Abstract

The invention relates to a method and device for rolling up a strip on a mandrel rotationally driven about the axis thereof by means of a rolling arrangement comprising a roller (3) for applying a strip (1) by the internal face (11) to the mandrel (2), means (62) for pushing the roller (3) to the mandrel (2) and a bending plate (4) whose curved surface (40) guides the strip (1) along the external face (20) of the mandrel (2). According to the invention, the application roller (3) is rotationally mounted on a movable supporting frame (6) which supports at least one hydraulic cylinder (62) in the form of pushing means producing a controllable clamping force for clamping the strip (1) between the mandrel and the application roller (3) and the supporting frame bears an additional roller (5) which is disposed immediately upstream of the application roller (3) and which supports the strip (1) taking into account a predictable folding effect (1) upstream of the application roller (3), wherein said application (3) and additional (5) rollers are rotatably driven in such a way they produces a friction drive force on the external (12) surface of the strip (1) in addition to the effect produced by mandrel on the internal surface (11) thereof.

Description

technical field [0001] [01] The object of the present invention is a winding method and apparatus for winding a strip body into a coil, and the invention is particularly applicable to winding a hot-rolled steel strip. Background technique [0002] [02] At the exit of a tropical train, the steel strip is generally sent on a table à rouleaux to one or more winders located some distance downstream of the table à rouleaux , generally under the shaker. [0003] [03] The belt is driven upstream of the winding machine by a clamping device followed by guide elements which guide the belt to a mandrin, the belt driven by friction It is wound on the revolving mandrel in superimposed turns. [0004] [04] In order to wind a new strip, the head of said strip is placed against the outer surface of the revolving drum in order to bring it downstream by friction, and it is then guided by a curved plate so that the strip The body bends along an increasing angular sector and remains attached...
