Abstract

A method of fabricating shell purfling strips having sufficient flexibility to be placed within a curved configuration. The shell purfling strips may be placed, as a single unit, in curved channels which require the strip to bend. The flexibility results from a laminated structure comprising a layer of binding material overlain by an organic shell layer, with a bonding agent attaching the layers together. The organic shell layer comprises a plurality of precisely placed breaks along its length. The binding material retains the individual fragments of the shell layer in the strip, but because the binding material comprises a flexible material, such as rubber, the layer of binding material is sufficiently flexible to allow the purfling strip to flex longitudinally and transversely. The shell purfling strips may be attached in parallel relationship to other perfling components allowing installation as a unit.
