Patent ID: 8794713

Claim:
A method of manufacturing a cosmetic applicator brush, the method comprising: using a stem pin to retain a multiplicity of fibers; in a primary twisting step, twisting the stem pin to form a twisted stem pin with a plurality of fiber arrays extending from the twisted stem pin; fixing a first region of the twisted stem pin, such that said first region is unable to twist further, the first region defining at least a first zone of the cosmetic applicator brush, the at least first zone in turn defining at least a first pitch between adjacent fiber arrays located within the first zone; and in a secondary twisting step, further twisting a second region of the twisted stem pin to define at least a second zone of the cosmetic applicator brush, the at least second zone in turn defining at least a second pitch between adjacent fiber arrays located within the second zone, with the at least first pitch being different to the at least second pitch; wherein the fiber arrays are trimmed between the primary and the secondary twisting step.
