Abstract

An actuating mechanism for varying the Venturi gap of a jet dyeing machine allows adjustment of the gap between a zero spacing (for easy centering) and a self-cleaning, fully open position, adjustment being provided without interrupting production. As is conventional, a textile material passing pipe is reciprocal within an outlet pipe, with an end of the textile material passing pipe forming a Venturi with a circumferential lip formed on the interior of the outlet pipe. A cam and follower mechanism is mounted exteriorly of the textile material-passing pipe between it and the outlet pipe, with a cam shaft extending through the outlet pipe wall to an exterior position. Power means, which may be responsive to sensors for sensing fabric flow and liquid flow, effect rotation of the cam shaft to effect reciprocation of the textile material-passing pipe, and thus adjustment of the Venturi gap.

Dependent claims

In an apparatus for the liquid treatment of textile material in rope form:

a first, textile material passing, pipe, having proximate and distal ends;
an outlet pipe generally concentric and in line with said first pipe, and at least said proximate end of said first pipe disposed within said outlet pipe;
a second, treatment liquid, inlet pipe, generally transverse to said outlet pipe, and opening into said outlet pipe at a portion thereof between said proximate and distal ends of said first pipe;
a circumferential projection formed on the interior of said outlet pipe downstream of the proximate end of said first pipe, said proximate end of said first pipe and said circumferential projection forming a Venturi;
means for reciprocating said first pipe with respect to said outlet pipe to vary the spacing between said circumferential projection and said first pipe proximate end, and thereby vary said Venturi;
said first pipe reciprocating means comprising means for engaging said first pipe at a portion thereof on the opposite side of said second pipe from said first pipe proximate end;
said engaging means:
actuatable from the exterior of said outlet pipe;
and isolated from the flow of treatment liquid in said second pipe and through said Venturi;
and isolated from the flow of textile material through said first pipe;
and non-concentric with said first pipe;
said means for reciprocating said first pipe comprising a cam and a cam follower mechanism disposed exteriorly of said first pipe between said first pipe and the interior wall of said outlet pipe, and disposed between the distal end of said first pipe and the opening of said second pipe into said outlet pipe.

In an apparatus for the liquid treatment of textile material in rope form:

a first, textile material passing, pipe, having proximate and distal ends;
an outlet pipe generally concentric and in line with said first pipe, and at least said proximate end of said first pipe disposed within said outlet pipe;
a second, treatment liquid, inlet pipe, generally transverse to said outlet pipe, and opening into said outlet pipe at a portion thereof between said proximate and distal ends of said first pipe;
a circumferential projection formed on the interior of said outlet pipe downstream of the proximate end of said first pipe, said proximate end of said first pipe and said circumferential projection forming a Venturi;
and means for reciprocating said first pipe with respect to said outlet pipe to vary the spacing between said circumferential projection and said first pipe proximate end, and thereby vary said Venturi;
said first pipe reciprocating means comprising a cam and a cam follower mechanism mounted exteriorly of said first pipe between said first pipe and the interior wall of said outlet pipe, and between said first pipe distal end and said second pipe connection to said outlet pipe.
