Abstract
Abstract The present disclosure is directed to an apparatus for the treatment of materials which comprises a heat-insulated treatment chamber, a plurality of sieve drum means subjected to a suction draft rotatably disposed within said treatment chamber, fan means associated with the sieve drum means for producing a suction draft and for circulating the treatment medium in said treatment chamber, heating means provided in the circulation zone of the treatment medium, tentering means containing tensioning chains at least partially disposed outside of the treatment chamber as inlet means, said tentering means cooperating with the sieve drum means for the effective conveyance of the material being treated to said sieve drum means, a supporting means disposed below the tensioning chains for supporting the material disposed on said chains so that the material is conveyed on the underside of the chains, and outlet means for removing the material being treated from the treatment chamber.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
215 words
An apparatus for the treatment of textile material which comprises a heat-insulated treatment chamber; a plurality of sieve drum means subjected to a suction draft rotatably disposed within said treatment chamber; fan means associated with the sieve drum means for producing a suction draft and for circulating a treatment medium in said treatment chamber; heating means provided in a circulation zone of the treatment chamber; inlet means for introducing a textile material into said treatment chamber, said inlet means including tentering means provided with tensioning chains and at least partially disposed outside the treatment chamber, said tEntering means cooperating with the sieve drum means for the effective conveyance of the textile material to said sieve drum means; a supporting means disposed below the tensioning chains for supporting the textile material disposed on said chains whereby the textile material is conveyed on the bottom side of the tensioning chains; a suction roller disposed between the tentering means and the first sieve drum means and below said tentering means at the inlet end of the treatment chamber, said suction roller facilitating the removal of the textile material from the tentering means and transferring the material to the lower portion of said first sieve drum means; and outlet means for removing the textile material from the treatment chamber.
Claim 2
Independent Claim
215 words
An apparatus for the treatment of textile material which comprises a heat-insulated treatment chamber; a plurality of sieve drum means subjected to a suction draft rotatably disposed within said treatment chamber; fan means associated with the sieve drum means for producing a suction draft and for circulating a treatment medium in said treatment chamber; heating means provided in a circulation zone of the treatment chamber; inlet means for introducing a textile material into said treatment chamber, said inlet means including tentering means provided with tensioning chains and at least partially disposed outside the treatment chamber, said tEntering means cooperating with the sieve drum means for the effective conveyance of the textile material to said sieve drum means; a supporting means disposed below the tensioning chains for supporting the textile material disposed on said chains whereby the textile material is conveyed on the bottom side of the tensioning chains; a suction roller disposed between the tentering means and the first sieve drum means and below said tentering means at the inlet end of the treatment chamber, said suction roller facilitating the removal of the textile material from the tentering means and transferring the material to the lower portion of said first sieve drum means; and outlet means for removing the textile material from the treatment chamber.
Claim 3
Dependent Claim
37 words
The apparatus of claim 1, wherein the suction roller contains a baffle plate which interrupts the flow of the suction draft at that portion of the roller which is not in contact with the material being treated.
Claim 4
Dependent Claim
27 words
The apparatus of claim 2, wherein the supporting means is a conveyor belt and the suction roller forms one of the reversing members of said conveyor belt.
Claim 5
Dependent Claim
29 words
The apparatus of claim 1, wherein means are provided for driving the supporting means at a variable speed in order to compensate for weft distortions in said textile material.
Claim 6
Dependent Claim
28 words
The apparatus of claim 1, wherein the supporting means comprises a plurality of spaced-apart bands associated with the tentering means on the side thereof carrying the textile material.
Claim 7
Dependent Claim
18 words
The apparatus of claim 5, wherein the bands diverge from each other, in the direction of material travel.
Claim 8
Independent Claim
182 words
An apparatus for the treatment of textile material which comprises a heat-insulated treatment chamber; a plurality of sieve drum means subjected to a suction draft rotatably disposed within said treatment chamber; fan means associated with the sieve drum means for producing a suction draft and for circulating a treatment medium in said treatment chamber; heating means provided in a circulation zone of the treatment chamber; inlet means for introducing a textile material into said treatment chamber, said inlet means including tentering means provided with tensioning chains and at least partially disposed outside of the treatment chamber, said tentering means cooperating with the sieve drum means for the effective conveyance of the textile material to said sieve drum means; a moving conveyor belt disposed below the tensioning chains and operatively associated with said tensioning chains for supporting the textile material disposed on said chains, said textile material being conveyed on the bottom side of the tensioning chains whereby textile material transfer is facilitated from said chains to the sieve drum means; and outlet means for removing the textile material from said treatment chamber.
