Abstract
Abstract An apparatus for continuous untwisting and crimping of a cloth, including, in a treating chamber, a pair of endless net conveyers spaced vertically apart and forming a gap therebetween to serve as a cloth passage. A plurality of jet pipes, each having a series of nozzles, are arranged to jet a high pressure fluid into the cloth passage. The jet pipes are provided in a zigzag up and down arrangement on the outside of the gap with the net conveyers between them. As a long knitted or woven cloth is passed continuously through the cloth passage while it receives the force of a fluid jetted zigzag from both sides, the cloth adopts a snaky or undulating state, and is stretched, beat and crumpled strongly so that the cloth is untwisted and crimped effectively.

Claim 1
Independent Claim

An apparatus for continuously untwisting and crimping of a cloth, comprising a treating chamber, a pair of endless net conveyers located in said treating chamber one positioned above the other forming a gap therebetween to serve as a cloth passage, a plurality of jet pipes each having a series of nozzles for jetting a high pressure fluid into the cloth passage, with said jet pipes arranged in a zigzag manner up and down on both outer sides of the gap within said net conveyers so that said nozzles direct the jets of high pressure fluid through said net conveyers into the gap, a support plate for each of said endless net conveyers, said jet pipes supported on said support plates supporting said endless net conveyers within which said jet pipes are arranged, means for moving at least one of said support plates toward and away from the other with the opposite ends of the support plate being movable independently of one another for varying the gap between said endless net conveyers and between said jet pipes so that the gap between said endless net conveyers can be uniform for the length thereof and so the gap can be of a variable dimension along the length, a pair of guide rollers located at the opposite ends of each said endless conveyers and said guide rollers supported on said support plate which supports said endless conveyer at the opposite ends of which said guide rollers are located, and second means mounted on said support plates for supporting each said pair of guide rollers for controlling the tension applied to said endless conveyers.

Claim 3
Dependent Claim
101 words
An apparatus for continuously untwisting and crimping of a cloth as set forth in claim 1, wherein the plurality of said jet pipes are divided into two groups with said jet pipes in each said group located above and below the gap formed by said conveyers, said jet pipes in each said groups are disposed in parallel, one said group having said jet pipes extending approximately perpendicularly to said net conveyers and the other said group having said jet pipes extending obliquely to said net conveyers, and said two groups alternating with one another along the length of said net conveyers.
