Abstract
Abstract An apparatus for the continuous steaming of natural and/or synthetic material including textile material or man-made fiber material, e.g. staple fibers, endless material and also synthetic fibers, webs, bonds, yarns and the like, comprising at least one housing shaped similarly to a bell, i.e. a housing formed into a chamber closed all around and open in the downward direction toward a mounting surface, steam producing means and/or steam feeding means being provided in the zone of the sidewalls within said housing; and at least one conveying means for the fibrous material which extends from below into the housing and extends out of the housing again at the bottom thereof.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
159 words
An apparatus for the continuous steaming of textile material or man-made fiber material, endless material and synthetic fibers which comprises at least one bell-shaped steam housing providing a treatment chamber closed all around by side walls and at least partly open at the bottom, said housing comprising a steamer hood that is arranged and supported on level-adjustable support means placed on a base surface, means for supplying steam into said chamber, at least one conveying means for transporting the material within said steamer hood whereby the material extends from below and into the steamer hood and extends out of the steamer hood at the bottom thereof, and said support means including lifting means for effecting vertical movement between the steamer hood and said conveying means whereby a steam atmosphere within said hood can be maintained while said conveying means is made accessible, said lifting means including telescopically extensible pistons for lifting the steamer hood away from said conveying means.
Claim 2
Independent Claim
159 words
An apparatus for the continuous steaming of textile material or man-made fiber material, endless material and synthetic fibers which comprises at least one bell-shaped steam housing providing a treatment chamber closed all around by side walls and at least partly open at the bottom, said housing comprising a steamer hood that is arranged and supported on level-adjustable support means placed on a base surface, means for supplying steam into said chamber, at least one conveying means for transporting the material within said steamer hood whereby the material extends from below and into the steamer hood and extends out of the steamer hood at the bottom thereof, and said support means including lifting means for effecting vertical movement between the steamer hood and said conveying means whereby a steam atmosphere within said hood can be maintained while said conveying means is made accessible, said lifting means including telescopically extensible pistons for lifting the steamer hood away from said conveying means.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1, wherein the means for supplying steam is a steam producing means arranged along the sidewalls.
Claim 4
Dependent Claim
19 words
The apparatus of claim 1, wherein means for supplying steam is a steam feeding means arranged along the sidewalls.
Claim 5
Dependent Claim
28 words
The apparatus of claim 1, wherein the means for supplying steam is a steam sump arranged in an open bottom portion of the housing defined by the sidewalls.
Claim 6
Dependent Claim
22 words
The apparatus of claim 1, wherein at least one steam collecting means is provided in a lower marginal zone of the housing.
Claim 7
Dependent Claim
18 words
The apparatus of claim 1, wherein the at least one steam collecting means is arranged outside the housing.
Claim 8
Dependent Claim
32 words
The apparatus of claim 1, wherein energy feeding means including hot-air pipes, steam pipes, water pipes and steam exhaust pipes are joined to the hood by elastic means or via telescoping conduits.
Claim 9
Independent Claim
131 words
An apparatus for the continuous steaming of textile material or man-made fiber material, endless material and synthetic fiber material which comprises at least one bell-shaped housing providing a treatment chamber closed all around by sidewalls and at least partly opened at the bottom, means for supplying steam into said chamber, and at least one conveying means for transporting the material within the housing, so that the material extends from below and into the housing and extends out of the housing at the bottom thereof; said means for supplying steam into said chamber including water sump means extending along the bottom portion of said bell-shaped housing and including a plurality of open channels spaced from each other to provide outlet openings for air removed from said textile material within said steam housing.
Claim 10
Independent Claim
131 words
An apparatus for the continuous steaming of textile material or man-made fiber material, endless material and synthetic fiber material which comprises at least one bell-shaped housing providing a treatment chamber closed all around by sidewalls and at least partly opened at the bottom, means for supplying steam into said chamber, and at least one conveying means for transporting the material within the housing, so that the material extends from below and into the housing and extends out of the housing at the bottom thereof; said means for supplying steam into said chamber including water sump means extending along the bottom portion of said bell-shaped housing and including a plurality of open channels spaced from each other to provide outlet openings for air removed from said textile material within said steam housing.
Claim 11
Dependent Claim
25 words
The apparatus of claim 8, wherein said housing is constructed as a horizontal steamer for the fixation especially of imprinted lengths of material, including carpets.
Claim 12
Dependent Claim
27 words
The apparatus of claim 9, wherein the channels which are open at the top are traversed by heating pipes, these channels being mounted to the housing sidewalls.
Claim 13
Dependent Claim
15 words
The apparatus of claim 9, wherein the housing is fashioned as a downwardly open hood.
Claim 14
Dependent Claim
19 words
The apparatus of claim 11, wherein steam suction removal means are arranged around a lower rim of the hood.
Claim 15
Dependent Claim
31 words
The apparatus of claim 12, wherein the lower rim of the hood and thus the steam level is provided shortly below a horizontally extending loaded face side of the conveying means.
Claim 16
Dependent Claim
68 words
The apparatus of claim 1, wherein said means for supplying steam comprises a saturated steam producing means including a water sump provided underneath the conveying means and covering the hood in the downward direction, said sump extending only partially across the width and length of a bottom open area of the hood and thus forming a plurality of air passages where the hood is open toward the bottom.
Claim 17
Dependent Claim
25 words
The apparatus of claim 14, wherein the air passages are provided in the zone of the textile material inlet between containers forming the water sump.
Claim 18
Dependent Claim
40 words
The apparatus of claim 14, wherein said means for supplying steam comprises water sump channels for producing saturated steam disposed additionally in the zone of the textile material inlet and along the lower edge of the hood and extend horizontally.
Claim 19
Dependent Claim
28 words
The apparatus of claim 16, wherein the channels are provided approximately at the level of, or optionally above, the conveying means on the inner wall of the hood.
Claim 20
Dependent Claim
35 words
