Abstract
A rubber foam tube () is produced by extruding a rubber composition into a tubular body () and feeding the tubular body () in an elongated state without cutting to pass the tubular body () through a microwave crosslinking device () and then through a hot air crosslinking device () for continuously foaming and crosslinking the rubber composition. At this time, a ratio V2/V1 between a speed V2 at which the tubular body () passes through the hot air crosslinking device () and a speed V1 at which the tubular body () passes through the microwave crosslinking device () is not less than 1.0 and not greater than 1.6.
