Abstract
Abstract The present disclosure is directed to apparatus for the treatment of materials which comprises a heat-insulated housing divided into a circulation chamber and a 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, perforated conveying means cooperating with the sieve drum means for the effective conveyance of the material being treated by free fall to said sieve drum means, and additional perforated conveying means disposed below the sieve drum means for guiding the material to outlet means for discharging the material being treated from the treatment chamber.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
286 words
An apparatus for the continuous treatment of textile materials with a gaseous treatment medium, which comprises a heat-insulated housing; baffle means in said housing for dividing the housing into a treatment chamber and a circulation chamber for the gaseous treatment medium; 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 the suction draft and for circulating the treatment medium through said treatment chamber and through said circulation chamber; heating means provided in the circulation chamber for heating the treatment medium circulated therethrough; a first perforated conveyor belt extending into the treatment chamber over the plurality of sieve drum means for introducing the textile material to be treated into the treatment chamber; a second perforated conveyor belt disposed in the treatment chamber extending under the plurality of sieve drum means and a third perforated conveyor belt disposed in the treatment chamber extending below the plurality of sieve drum means and above the second perforated conveyor belt; said textile material passing from said first perforated conveyor belt by free fall onto the initial material receiving sieve drum means, passing over portions of each of the successive sieve drum means, and then passing from the last material receiving drum means by free fall to the second perforated conveyor belt whereby said textile material is continuously subjected to said circulating treatment medium; said third perforated conveyor belt acting together with said second perforated conveyor belt to guide the material beneath the sieve drum means and to prevent the material from lifting from said second perforated conveyor belt; and outlet means through which the material being treated is discharged from the treatment chamber.
Claim 2
Independent Claim
286 words
An apparatus for the continuous treatment of textile materials with a gaseous treatment medium, which comprises a heat-insulated housing; baffle means in said housing for dividing the housing into a treatment chamber and a circulation chamber for the gaseous treatment medium; 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 the suction draft and for circulating the treatment medium through said treatment chamber and through said circulation chamber; heating means provided in the circulation chamber for heating the treatment medium circulated therethrough; a first perforated conveyor belt extending into the treatment chamber over the plurality of sieve drum means for introducing the textile material to be treated into the treatment chamber; a second perforated conveyor belt disposed in the treatment chamber extending under the plurality of sieve drum means and a third perforated conveyor belt disposed in the treatment chamber extending below the plurality of sieve drum means and above the second perforated conveyor belt; said textile material passing from said first perforated conveyor belt by free fall onto the initial material receiving sieve drum means, passing over portions of each of the successive sieve drum means, and then passing from the last material receiving drum means by free fall to the second perforated conveyor belt whereby said textile material is continuously subjected to said circulating treatment medium; said third perforated conveyor belt acting together with said second perforated conveyor belt to guide the material beneath the sieve drum means and to prevent the material from lifting from said second perforated conveyor belt; and outlet means through which the material being treated is discharged from the treatment chamber.
Claim 3
Dependent Claim
29 words
The apparatus of claim 1, in which the first perforated conveyor belt is operatively associated with a tentering means provided with tensioning chains and pins for engaging said material.
Claim 4
Dependent Claim
45 words
The apparatus of claim 2, in which an unpinning transfer means is associated with the tensioning chains for removing the material being treated from the pins of said chains and For allowing the material to pass by free fall onto the initial sieve drum means.
Claim 5
Dependent Claim
23 words
The apparatus of claim 1, in which the plurality of sieve drum means are arranged in a single row within said treatment chamber.
