摘要： The present invention relates to a polymeric article having grooves formed by a microreplication tool. The microreplication tool includes a cylindrical workpiece having adjacent longitudinally-extending grooves in a cylindrical workpiece. Forming the adjacent longitudinally-extending grooves in the cylindrical workpiece comprises the steps of:
(a) forming, beginning near a first end of the workpiece, an initial portion of each groove; and
(b) forming subsequent portions of each groove during successive revolutions of the workpiece, the subsequent portions being substantially aligned with the initial portion of each groove, the subsequent portions being formed progressively closer to a second end of the workpiece. The grooves formed by the microreplication tool in the polymeric article correspond to the adjacent longitudinally-extending grooves in the cylindrical workpiece, wherein the grooves formed in the polymeric article define lengths in a longitudinal dimension and widths in a lateral dimension that is perpendicular to the longitudinal dimension. For each of the grooves formed in the polymeric article, a length of the groove is greater than a width of the groove. The initial portions of the grooves formed near the first end of the workpiece are all relatively sharper than all the subsequent portions of each of the grooves formed closer to the second end of the workpiece, wherein the polymeric article includes the grooves formed by the microreplication tool such that each portion of each of the grooves on a first side of the polymeric article are all relatively sharper than each portion of all the grooves positioned closer to a second side of the polymeric article, the first side of the polymeric article opposing the second side of the polymeric article in the longitudinal dimension.
