Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
67 words
The method of producing combined strand of the type in which feeder strands from a plurality of feeder packages are gathered into a combined strand, wherein the improvement comprises: sensing the cessation of passage of a strand from any of said feeder packages into said combined strand; and, introducing an auxiliary strand into fixed engagement with said combined strand or a feeder strand responsive to said sensing.
Claim 2
Independent Claim
67 words
The method of producing combined strand of the type in which feeder strands from a plurality of feeder packages are gathered into a combined strand, wherein the improvement comprises: sensing the cessation of passage of a strand from any of said feeder packages into said combined strand; and, introducing an auxiliary strand into fixed engagement with said combined strand or a feeder strand responsive to said sensing.
Claim 3
Dependent Claim
24 words
The method of claim 1 in which said auxiliary strand is introduced into fixed engagement with a feeder strand within a hollow feeder package.
Claim 4
Dependent Claim
16 words
The method of claim 2 in which said auxiliary strand is carried by a gaseous fluid.
Claim 5
Dependent Claim
31 words
The method of claim 2 in which said auxiliary strand is introduced into the interior of a feeder package along a line substantially equidistant from the sides of said feeder package.
Claim 6
Dependent Claim
69 words
Apparatus for producing a combined strand of the type in which feeder strands from a plurality of feeder packages are gathered into a combined strand, wherein the improvement comprises: sensing means for sensing the cessation of passage of a feeder strand to said combined strand; and, introduction means responsive to said sensing means for introducing a auxiliary strand into fixed engagement with said combined strand or a feeder strand.
Claim 7
Dependent Claim
69 words
Apparatus for producing a combined strand of the type in which feeder strands from a plurality of feeder packages are gathered into a combined strand, wherein the improvement comprises: sensing means for sensing the cessation of passage of a feeder strand to said combined strand; and, introduction means responsive to said sensing means for introducing a auxiliary strand into fixed engagement with said combined strand or a feeder strand.
Claim 8
Dependent Claim
24 words
The apparatus of claim 5 in which said introduction means is adapted to introduce said auxiliary strand into the interior of a feeder package.
Claim 9
Dependent Claim
13 words
The apparatus of claim 6 where said means for inserting comprises a conduit.
Claim 10
Dependent Claim
28 words
The apparatus of claim 6 where said introduction means is positioned to insert said auxiliary strand along a line substantially equidistant from the sides of said feeder package.
