Abstract
A first yarn is combined with a second yarn from one or more yarn packages thereof by a device which includes a yarn holder adapted to hold first yarn wound thereon, the yarn holder having an axial passage through which the secone yarn travels, a guide at the exit end of the holder for guiding the first yarn into engagement with the second yarn as the first yarn unwinds from the holder, and a support for the holder. The support together with the yarn holder pivots about the guide so that the holder is automatically aligned with the second yarn even though the second yarn varies in its angle of delivery to the holder. The second yarn thus carries the first yarn as the first yarn is wound about the second yarn.

In a device for combining a first yarn and a second yarn, the combination of:
- a yarn holder adapted to hold first yarn wound thereon, said yarn holder having an axial passage for travel therethrough of a second yarn delivered from a yarn package spaced apart from said yarn holder;
- guide means at the exit end of said yarn holder for guiding said first yarn to engagement with said second yarn whereby said first yarn is wrapped about and carried by said second yarn as said first yarn unwinds from said yarn holder;
- and
- support means supporting said yarn holder, said support means being adapted to pivot with said yarn holder about said guide means whereby said yarn holder aligns itself with the angle of delivery of said second yarn to said yarn holder.
A method of combining a first yarn and a second yarn supplied from spaced apart first and second yarn packages respectively, utilizing a device comprising the combination of a yarn holder and said first yarn wound thereon, said yarn holder having an axial passage for travel therethrough of said second yarn, guide means at the exit end of said yarn holder for guiding said first yarn to engagement with said second yarn, and support means supporting said yarn holder, said support means being adapted to pivot with said yarn holder about said guide means whereby said yarn holder aligns itself with the angle of delivery of said second yarn to said yarn holder;
- said method comprising continuously passing said second yarn through said yarn holder and said guide means, engaging said first yarn with said second yarn between the exit of said yarn holder and said guide means, whereby said first yarn is wrapped about and is carried by said second yarn as said first yarn unwinds from said yarn holder.
