ABSTRACT:
A device for deflecting a continuously supplied thread by means of a curved guide tube. The guide tube is formed of a plurality of contiguously abutting segments which are disposed between the entry and exit openings of a casing. The space between the inner wall of the casing and the outer circumference of the segments is filled with a bonding agent which fixes the segments in the desired spatial curvature for the guide tube when it hardens. Furthermore, a method for producing such device is disclosed which utilizes an expandable mandrel to hold the segments in the desired spatial curvature position prior to being fixed in position by the bonding agent.
