Abstract

Production of flexible internally smooth corrugated tube with an inner smooth metal band (4) of the same width as the outer bent metal band (2). The corrugated tube has a bent groove (16) passing along the center. Independent claims are included for: (1) a device for carrying out the process; (2) a corrugated tube with an inner band in stainless steel.
