Strip coiler

In a strip coiler for the winding up and unwinding of thin strip material of metal, with a rotatably supported horizontal coiler mandrel for receiving a coil of said strip, and at least one smoothing roll adjustable with respect to the coiler mandrel for pressing the strip against the coil, and with a control of the horizontal desired position of the smoothing roll;

• the improvement comprising means for regulating the position (6') of the smoothing roll (6) in dependence on an inclined position (6'', 6'") of the smoothing roll (6) relative to the coiler mandrel caused by irregularities in the strip (2), the line connecting the coil axis and the point of tangency where the strip first contacts the coil and the line between the point of application of said smoothing roll against the coil and the coil axis being spaced apart by a predetermined distance (a) at the points where said intersect the coil surface, said lines forming with the axis of the coiler mandrel an acute dihedral opening away from said axis, there being straight elongated levers (7) carrying the smoothing roll (6), and means for moving said levers (7) in a direction parallel to their length thereby to maintain said distance (a) constant despite changes in the diameter of the coil (5).
