A method for manufacturing a plurality of labeling bands includes extruding an elastic material, co-extruding a label material with the elastic material, curing the elastic material and the label material, and locating a plurality of demarcations at intervals along the length of the tube to define the plurality of labeling bands. Co-extruding the label material with the elastic material includes forming a tube having an outer surface, an inner surface and a length, so that the label material forms a stripe on the outer surface. In another aspect, an article of manufacture includes an endless band of a first elastic material and a label of a second material embedded into an outer surface of the endless band. The endless band includes the outer surface, an inner surface and first and second opposed perimeter edges, each of the first and second opposed perimeter edges having a common unstretched perimeter dimension.

A floor may include a substrate having a top side and a bottom side. A top layer may be provided on the substrate. The top layer may consist of a printed thermoplastic film and a thermoplastic transparent or translucent layer provided on the printed thermoplastic film. The top layer may be directly adhered to the substrate by heat welding the printed thermoplastic film and the top side of the substrate, in the absence of a glue layer. The substrate may be a synthetic material board including a filler. The substrate at least at two opposite edges may include coupling means provided in the synthetic material board. The thermoplastic transparent or translucent layer may be provided with a structure.

A fluid conveying apparatus is disclosed. The apparatus comprises a circular tubing. The circular tubing further comprises an internal surface and an external surface. The internal surface encloses a circular passage for conveying a fluid and the external surface is disposed concentric to the internal surface, and distal to the circular passage. Further, the circular tubing comprises a plurality of channels disposed along a periphery of the circular tubing sandwiched between the internal surface and the external surface.

A catheter is made by coextruding first and second molten polymers, wherein the second molten polymer forms a flexible inner core and the first molten polymer forms exactly two bands on opposite sides of the inner core. The inner core is braided, and a third molten polymer extruded onto the braid to form a flexible jacket that encloses the braid, the bands and the inner core. The bands are more rigid than the inner core, and they provide preferential in-plane bending.

A novel tubular or profile shapes of co-extruded multilayer polymers. These materials contain tens to thousands of layers of milli-, micro- to nano-polymer layers. These new shapes contain contiguous layers of milli- to nano-polymer layers in three dimensions and these contiguous layers may be twisted or turned to further expand the potential microlayer geometries.

The disclosed embodiments relate to extrusion systems and involves a method to promote self-balancing of flow velocity while enhancing the strength of the end product by off-setting seams. This invention focuses on using a system of more than one deflector to produce multiple rings which are then quickly merged to produce a more quickly balanced ring.
