Abstract
Roving or beaming method and apparatus are provided in which a combined strand is produced from feeder packages. The passage of the strands from each feeder package is sensed, and the cessation of passage of strand from any one of the feeder packages results in the addition of a strand from an auxiliary package. Where strands are unwound from hollow feeder packages the auxiliary strand can be inserted into the interior of a feeder package for engagement with one of the feeder strands being unwound.
