A substitute for natural centre cane is made by extruding a foamed synthetic thermoplastic material through a die orifice which is radially notched to provide longitudinally extending ribs on the extrudate. Preferably two thermoplastics are used, the extrusion temperature being that normally used for one of the components, e.g. the extrusion of a mixture of polyethylene and polypropylene in the temperature range 170-190‹ C. which is below the temperature at which polypropylene is normally extruded. Preferably also, a yellow colouring agent is added. The die orifice may be essentially circular or semi-circular to simulate split cane. The extrudate on leaving the die is passed into a cold water tank via an air gap. Typical specific gravities for the cane substitute are from 0.55-0.60, the actual value depending on the amount of blowing agent used, the extrusion temperature and the length of the air gap. Another thermoplastics mixture mentioned is unplasticized P.V.C. with polyethylene.
