Abstract
An apparatus for twisting together a first and second yarn has a frame extending in a longitudinal direction and carrying a row of upright spindles each having and rotatable about an upright spindle axis. A holder is carried on the frame above each spindle and in turn carries a pair of yarn supplies one which may be the first yarn and one the second, or both the first. When the holder carries both first and second yarn supplies the spindle is operated as a takeup spool and is provided with a traveling-ring arrangement, with the two yarns being pulled off the respective supplies and twisted together. When the holder carries only two supplies of the first yarn the supply of the second yarn can be carried on the spindle, and a separate takeup spool can be provided above the spindle and below the holder. This takeup spool is driven to take up the two yarns and the first yarn is fed from the holder down and then up through the hollow spindle to be twisted with the second yarn that is simultaneously being spun.
