Abstract
Abstract An apparatus for wet-treating, particularly for dyeing, a fabric in the form of a continuous circulating rope of cloth, wherein the rope of cloth is fed into a kier by introducing it by means of a treating liquid and is moved farther within the kier. The treating liquid is circulated through outlets out of the kier and through inlets into the kier when feeding-in the rope of cloth by means of said liquid. The rope of cloth is fed-in into a drum pivoted in the kier, is moved together with this drum along a part of the circumference of said kier and is removed from the drum in order to be repeatedly fed-in. The treating liquid is removed from the drum after the feeding-in of the rope of cloth, and that part of the rope of cloth which is actually within the drum is deposited therein in a non-floating state.

Claim 1
Independent Claim
150 words
An apparatus for wet-treating, particularly for dyeing, a fabric in the form of a continuous circulating rope of cloth, comprising a kier for taking up a considerable length of rope of cloth, a feeding-in device for the introduction of the rope of cloth into the kier by means of a treatment liquid, a circulating pump for the treatment liquid having its suction side fitted onto the kier and its pressure side fitted onto the feeding-in device, a drum rotatably mounted in the interior of the kier, said drum having a wall including throughpassage means for introducing the rope of cloth interiorly of said drum, the rope of cloth, by means of said feeding-in device, being introduced exclusively into said drum and means for enabling the treatment liquid to pass from the inside of the drum into that part of the interior of the kier which is situated outside the drum.
Claim 2
Independent Claim
150 words
An apparatus for wet-treating, particularly for dyeing, a fabric in the form of a continuous circulating rope of cloth, comprising a kier for taking up a considerable length of rope of cloth, a feeding-in device for the introduction of the rope of cloth into the kier by means of a treatment liquid, a circulating pump for the treatment liquid having its suction side fitted onto the kier and its pressure side fitted onto the feeding-in device, a drum rotatably mounted in the interior of the kier, said drum having a wall including throughpassage means for introducing the rope of cloth interiorly of said drum, the rope of cloth, by means of said feeding-in device, being introduced exclusively into said drum and means for enabling the treatment liquid to pass from the inside of the drum into that part of the interior of the kier which is situated outside the drum.
Claim 3
Dependent Claim
33 words
