Making a composite profiled wire

Abstract

A profiled wire such as a toothed card roll wire, is made by first fitting together at least two longitudinally extending starting wires each of a predetermined cross-sectional size and each having a longitudinally extending surface region by engaging the regions together transversely and thereby forming a longitudinally extending interface. The fitted-together wires are then bonded together at the interface and the joined wires are subsequently profile pressed, that is deformed by rolling or drawing, while maintaining constant the relationship between the cross-sectional sizes perpendicular to the longitudinal direction of the starting wires. A toothed wire for a card roll can be made by further forming one of the profiled sections as a root section to be seated into a groove of the card roll and the other section as a blade with card teeth therein and hardening the formed blade section.
