US Patent:

50462091, Sep 10, 1991

Filed:

Apr 20, 1990

Appl. No.:

7/511466

Inventors:

Hans O. Keilhack - Charlotte NC

Assignee:

Keiltex Corporation - Charlotte NC

International Classification:

D06B 316
D06B 332

US Classification:

8152

Abstract:

A batch dyeing machine 10 has separate imperforate compartments A and B for facilitating washing of a length of fabric as it is transported from one compartment to the other. A squeeze roll 50 prevents used wash water from passing from one compartment into the other with the fabric. By separating the compartments, wash liquid is conserved in that only one of the compartments need be filled at a time and a counterflow wash system is provided. Thus, the washing capabilities of a batch dyeing machine have been enhanced.

US Classification:

Abstract:

An improved web winder and compensator apparatus with automatic web winding speed compensating controls for selectively winding or unwinding at a uniform tension a roll of traveling continuous web material being selectively fed from or taken up by an associated mechanism, as follows. A tension compensator device passes the traveling web therethrough and compensates for variations in speed of travel of the web for maintaining a uniform tension therein. The compensator device preferably includes stationary rolls for guiding the web through the compensator device and counterbalanced movable rolls for receiving the traveling web therearound and for moving toward and away from the stationary rolls for decreasing and increasing the length of the path of travel of the web through the compensator in relation to the tension on the traveling web. The movable rolls are preferably movable to a threading position for straightline linear threading up of the web through the compensator device. A variable speed, center drive, reversible winder mechanism is positioned adjacent the compensator device for selectively winding or unwinding a roll of the web material.
