Abstract
Abstract A partitioned spinning shaft to receive and separate filaments converging downwardly in their direction of travel from a plurality of spinning heads in a melt-spinning apparatus, the partitions being adjustably mounted to provide shaft sections of a predetermined narrowing width corresponding closely to the converging paths of the separated filaments without contacting the filaments.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
146 words
In an apparatus for the melt-spinning of filaments including a plurality of at least three spinning heads arranged laterally across the top portion of a common vertically elongated spinning shaft which is partitioned into a corresponding plurality of approximately vertical shaft sections separating the filaments drawn downwardly from each spinning head in converging paths, the improvement which comprises: individual partitions adjustably mounted in at least the lower portion of the common shaft For selected displacement in the direction of the shaft width, thereby variably narrowing each shaft section to accommodate the converging paths of said separated filaments while remaining free of contact therewith; laterally positioned fastening means secured to at least one of the upper and lower edges of each of said partitions; and means to adjustably mount said fastening means at different positions on the front and back walls of said common vertically elongated shaft.
Claim 2
Dependent Claim
146 words
In an apparatus for the melt-spinning of filaments including a plurality of at least three spinning heads arranged laterally across the top portion of a common vertically elongated spinning shaft which is partitioned into a corresponding plurality of approximately vertical shaft sections separating the filaments drawn downwardly from each spinning head in converging paths, the improvement which comprises: individual partitions adjustably mounted in at least the lower portion of the common shaft For selected displacement in the direction of the shaft width, thereby variably narrowing each shaft section to accommodate the converging paths of said separated filaments while remaining free of contact therewith; laterally positioned fastening means secured to at least one of the upper and lower edges of each of said partitions; and means to adjustably mount said fastening means at different positions on the front and back walls of said common vertically elongated shaft.
Claim 3
Dependent Claim
51 words
Apparatus as claimed in claim 1 wherein said fastening means includes a laterally extending rod member projecting from opposite sides of the partition and a slotted supporting member to receive each projecting end of the rod with means to tightly secure said rod ends in the supporting members at predetermined positions.
Claim 4
Dependent Claim
44 words
Apparatus as claimed in claim 1 wherein said partition is a preshaped, thin, flexible sheet metal plate, and said fastening means includes a laterally extending rod member projecting from opposite sides of the partition with the projecting ends rotatably secured in a predetermined position.
Claim 5
Dependent Claim
84 words
Apparatus as claimed in claim 1 wherein said partition is a preshaped, thin, flexible sheet metal plate, and said fastening means includes a laterally extending rod member projecting from opposite sides of the position, said rod member being adjustably secured to the plate at positions parallel to the adjacent edge of said plate and having its projecting ends adjustably mounted for both rotatably positioning the rod about its longitudinal axis and shiftable displacement of said rod into parallel positions in an approximately horizontal plane.
Claim 6
Dependent Claim
38 words
Apparatus as claimed in claim 1 including at least two vertically superimposed adjustable partitions extending over both the upper and lower portions of each shaft sections and having their adjoining edges interconnected by said laterally positioned fastening means.
Claim 7
Dependent Claim
27 words
Apparatus as claimed in claim 5 wherein each of the upper and lower edges of all vertically superimposed partitions are secured to a laterally positioned fastening means.
