Abstract
Abstract In a suction device for removing liquids from textile fabrics, there is provided a tubular body that is adapted to be connected to a suction unit. The tubular body has at least two longitudinal angularly spaced apart passages through the wall thereof. At least three sectors are attached to the outer surface of the body in order to define, with their respective, opposed edges, at least two longitudinal slots that are in registration with the passages in a tubular body. A roller is positioned intermediate the slots and tangentially to the body for advancing the fabric past the slots. A shower head may be provided for ejecting a fabric treating liquid.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
102 words
Suction device for removal of liquids from textile fabrics subjected to washing, sizing and the like treatments, said device comprising: a tubular body defining an axial suction conduit for connection to a central suction unit; at least two passages in the said body, said passages being radial, longitudinal and angularly spaced from one another; at least three cylindrical sectors attached on the outer surface of said body to define with their respective contiguous borders at least two longitudinal slots in juxtaposition with said passages; a roller positioned externally of said body and between said slots for advancing said fabric past said slots.
Claim 2
Dependent Claim
102 words
Suction device for removal of liquids from textile fabrics subjected to washing, sizing and the like treatments, said device comprising: a tubular body defining an axial suction conduit for connection to a central suction unit; at least two passages in the said body, said passages being radial, longitudinal and angularly spaced from one another; at least three cylindrical sectors attached on the outer surface of said body to define with their respective contiguous borders at least two longitudinal slots in juxtaposition with said passages; a roller positioned externally of said body and between said slots for advancing said fabric past said slots.
Claim 3
Dependent Claim
30 words
The device according to claim 1, wherein said passages are longitudinally shorter than the length of said body, and wherein said sectors are at least as long as the passages.
Claim 4
Dependent Claim
28 words
The device according to claim 1, wherein said sectors are attached to said tubular body so as to be reciprocally positionable for varying the width of said slots.
Claim 5
Dependent Claim
20 words
