ABSTRACT:
A method for making flexible, corrugated rubber tubing of dual composition from two extruded sleeves of uncured rubber. The inner diameter of one of the sleeves is approximately equal to the outer diameter of the other sleeve. The first sleeve is slid axially onto an elongated internal forming member, after which the second sleeve is slid over the first sleeve. An external forming means is then placed around the assembled sleeve and used to form corrugations in the pair of sleeves simultaneously, and thus intermittently interlock the two sleeves in a preshaped condition to form a unitary corrugated product. The resulting product is then heat-treated to set the corrugations and form a flexible corrugated tube length of dual composition.
