Abstract
Abstract This invention is directed to a system for impregnating with liquid ammonia and drying a continuously advancing narrow fabric tape or ribbon and includes an initial impregnating and aging section, a primary drying section provided with an apparatus comprising a plurality of vertically aligned horizontal dryer drums each of which carries a plurality of wraps of the tape and each of which is provided with a plurality of sets of guide rolls for controlling each wrap of the tape, and a final steaming and drying section provided with at least one horizontal dryer drum that also carries a plurality of wraps of the tape under the control of a corresponding number of sets of guide rolls.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
132 words
In a system for impregnating with liquid ammonia and drying a continuously advancing narrow fabric tape, an apparatus for controlling wraps of the tape around a rotating cylinder, a first pair of guide means each adapted for guiding the tape thereabout and located in proximity to said cylinder, a second pair of guide means each adapted for guiding the tape thereabout and disposed in spaced relation to said first pair of guide means, said pairs of guide means lying in a plane substantially parallel with a plane tangent to said cylinder, and a separate guide means located outwardly from said pairs of guide means and adapted to receive the tape from one of said pairs of guide means and to deliver the tape to thE other of said pairs of guide means.
Claim 2
Dependent Claim
132 words
In a system for impregnating with liquid ammonia and drying a continuously advancing narrow fabric tape, an apparatus for controlling wraps of the tape around a rotating cylinder, a first pair of guide means each adapted for guiding the tape thereabout and located in proximity to said cylinder, a second pair of guide means each adapted for guiding the tape thereabout and disposed in spaced relation to said first pair of guide means, said pairs of guide means lying in a plane substantially parallel with a plane tangent to said cylinder, and a separate guide means located outwardly from said pairs of guide means and adapted to receive the tape from one of said pairs of guide means and to deliver the tape to thE other of said pairs of guide means.
Claim 3
Dependent Claim
23 words
