An apparatus for spinning bicomponent sheath/core filaments such that the filaments are uniformly quenched. The apparatus includes a distributor plate, and spinneret and a shim position between the distributor plate and the spinneret. The spinneret includes a plurality of holes positioned so that the density of holes is the lowest near the center of the spinneret and increases as radially proceed outward. More specifically, the holes are substantially configured in the shape of a parallelogram in which the sides of the parallelogram are all of equal length. Additionally, the shape of the parallelogram is more flat the further the parallelogram pattern is located from the center of the spinneret. In this manner of positioning the holes, filaments therefrom do not significantly impede quench air from uniformly reaching filaments in the outer rows.
