ABSTRACT:
A variable capacity strip accumulator for steel strip travelling continuously from upstream reels of supply to a downstream treating or processing station, said accumulator having adjacent spiral coils rotatable on a common axis for accumulating a supply of the strip for continuous feeding cut of the accumulator despite a temporary stoppage of supply. In the execution of this objective, the convolutions of the two coaxial spiral coils of opposite hand are connected together by a transition curve into one continuous web. Strip guides for said curve first slightly twist the strip in the same direction as its first spiral to an extent of approximately 90.degree., while withdrawing it from the interior of the latter in the direction away from said coils and without substantially departing from its radius of curvature, crossing the axis at the farthest point. Continuing at the same curvature and rate of twist of 90.degree. on its return branch, the strip reaches, and is joined to, the second coil at a point substantially antipodal to the point of departure from the first spiral and twisted by 180.degree.. The above procedure results in the reversal of direction of winding of the convolutions of the strip in the two coils without subjecting it to any more tending than in the coils.
