A non-pneumatic and method of making a non-pneumatic tire. The non-pneumatic tire includes a lower ring having a first diameter and an upper ring having a second diameter greater than the first diameter. The upper ring is substantially coaxial with the lower ring. A support structure extends between the lower ring and the upper ring. The support structure includes a first face and a second face opposite the first face, a first axial edge and a second axial edge. The first and second axial edges space the first face from the second face. At least one of the first edge and the second edge may have a geometry that provides the support structure with a nonrectangular cross section. At least one of the first face and the second face may have a surface roughness of less than 25 microns. The support structure may be free from orthogonal axial edges.

A non-pneumatic tire includes an inner ring, an outer ring, and a plurality of loops extending between the inner ring and the outer ring. The plurality of loops including at least a first loop and a second loop, wherein the first loop and the second loop are each in direct contact with both the inner ring and the outer ring. The first loop has a single reinforcement layer disposed therein, and includes a first extent that extends between the inner ring and the outer ring and a second extent that extends between the inner ring and the outer ring. The second loop has a single reinforcement layer disposed therein, and includes a third extent that extends between the inner ring and the outer ring and a fourth extent that extends between the inner ring and the outer ring. The second extent is in direct contact with the third extent.

A non-pneumatic tire includes an inner ring having an axis of rotation and an outer ring coaxial with the inner ring. The non-pneumatic tire further includes support structure extending from the inner ring to the outer ring and a circumferential tread extending about the outer ring. The circumferential tread includes a band layer constructed of a single material and a tread rubber layer directly attached to the band layer.

An improved embroidery hoop is provided. The hoop includes a closed outer loop having a receiving groove in an inner perimeter surface. The receiving groove cooperates with and receives a retaining loop according to a predetermined fit appropriate for holding a fabric workpiece. The outer loop is rigid while the inner retaining loop is sufficiently flexible to be fitted by hand in the receiving groove. The embroidery hoop may optionally include a pull tab for assisting a user in removing the retaining loop from the receiving groove. Moreover, the outer perimeter of the outer loop has a geometry that is arbitrary and independent of the geometry of the receiving groove and retaining loop. Accordingly, the outer loop may comprise fanciful designs.
