Abstract

Abstract A synthetic fibre spinning and reeling machine comprising at least one row of spinning units. In each unit the rows of spinnerets and the axles of the rollers and rolls in the finishing and reeling device are disposed transversely to the longitudinal axes of the row of units in which that unit lies. In the case of two rows of units common drive arrangements are provided. The machine provides ready access to the rolls and yet at the same time does not undesirably twist the fibres during their transit from the spinnerets to the rolls.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 258 words
In a spinning apparatus for producing and reeling synthetic fibers from a melt by spinning means including spinnerets with orifices arranged in at least one row to receive a supply of said melt from a respective pump means, air blowing means located relative to said spinnerets for supplying a flow of air to fibers produced by said spinnerets, said spinning means further including finishing and take-up roller means located vertically below said air blowing means, said apparatus having a longitudinal main axis, the improvement comprising a horizontal supporting stage, apertures in said supporting stage, a plurality of spinning Units supported on said stage in vertical alignment with said apertures, each unit including said spinning means, each spinning unit having a longitudinal vertical axis, said spinning units being arranged in parallel to each other so that each vertical spinning unit axis extends perpendicularly to said longitudinal apparatus main axis, and wherein said finishing and take-up roller means of each spinning unit comprise a plurality of cooperating rollers arranged below said stage substantially adjacent to the respective vertical axis to define a corresponding plurality of vertical paths for the produced fibers, said path extending through said apertures in said stage, said vertical paths also extending substantially in parallel to each other so as to keep the synthetic fibers produced by one spinning unit on a substantially vertical path for its entire length of travel from the spinneret to the take-up roller means and thus out of the vertical path of the synthetic fibers produced by an adjacent parallel spinning unit.
Claim 2
Dependent Claim 258 words
In a spinning apparatus for producing and reeling synthetic fibers from a melt by spinning means including spinnerets with orifices arranged in at least one row to receive a supply of said melt from a respective pump means, air blowing means located relative to said spinnerets for supplying a flow of air to fibers produced by said spinnerets, said spinning means further including finishing and take-up roller means located vertically below said air blowing means, said apparatus having a longitudinal main axis, the improvement comprising a horizontal supporting stage, apertures in said supporting stage, a plurality of spinning Units supported on said stage in vertical alignment with said apertures, each unit including said spinning means, each spinning unit having a longitudinal vertical axis, said spinning units being arranged in parallel to each other so that each vertical spinning unit axis extends perpendicularly to said longitudinal apparatus main axis, and wherein said finishing and take-up roller means of each spinning unit comprise a plurality of cooperating rollers arranged below said stage substantially adjacent to the respective vertical axis to define a corresponding plurality of vertical paths for the produced fibers, said path extending through said apertures in said stage, said vertical paths also extending substantially in parallel to each other so as to keep the synthetic fibers produced by one spinning unit on a substantially vertical path for its entire length of travel from the spinneret to the take-up roller means and thus out of the vertical path of the synthetic fibers produced by an adjacent parallel spinning unit.
Claim 3
Dependent Claim 83 words
The spinning apparatus according to claim 1, wherein said air blowing means comprise blowing channel means including a vertical blowing housing (8) having one open vertical side and means (6, 7) for selectively closing said housing on two sides located opposite each other, as well as an air supply channel (9) located opposite said one open vertical side and tapering upwardly so as to deflect air into and through said housing substantially in a direction extending in parallel to said main apparatus axis.
Claim 4
Dependent Claim 36 words
The spinning apparatus according to claim 2, wherein said blowing means further comprise grid means (22) located between said tapering air supply channel (9) and said housing (8) for steadying the air flow through the housing.
Claim 5
Dependent Claim 27 words
The spinning apparatus according to claim 2, further comprising a spinning channel (10, 11) disposed vertically between said blowing housing (8) and said finishing and reeling means.
Claim 6
Dependent Claim 33 words
The spinning apparatus according to claim 1, wherein said plurality of spinning units (1, 2) are arranged in rows and columns whereby all units are arranged vertically and in parallel to each other.
Claim 7
Dependent Claim 44 words
The spinning apparatus according to claim 5, further comprising drive means for said pump means, said drive means including drive axles disposed transversely to the rows of spinning units and passing through one row of spinning units to the other row of spinning units.
