ABSTRACT:
A tube is held or guided parallel to its length by providing a channel-like structure aligned with the tube and having sides which are spaced apart by a distance less than the diameter of the tube. Circumferentially spaced longitudinal portions of the outer surface of the tube bear respectively on the two sides of the channel. The channel is open to the outer surface of the tube between those longitudinal portions, and the bottom of the tube is spaced from the outer surface of the tube between those longitudinal portions. The tube is held against the channel-like structure by directing a stream of gas (e.g., air) along the channel.
