ABSTRACT:
A method of reducing slot width in slotted tubular liners. A slotted tubular liner (1) is provided having an interior surface (3), an exterior surface (2) and a plurality of slots (4) extending between the interior surface and the exterior surface. One or more contoured rigid forming tools (7) are provided. Pressure is applied to either the interior surface (3) or the exterior surface (2) of the slotted tubular liner (1) with the contoured rigid forming tools (7). The contoured rigid forming tools are then moved in a sweep pattern traversing either the interior surface or the exterior surface of the slotted tubular liner, until plastic deformation narrows the width of the plurality of slots (4) to within desired tolerances. The method does not require the same precise positioning of previously known methods and, as such, provides a combination of increased output and lower cost.
