Abstract
The process and apparatuses for the continuous application of liquors to a moving textile fiber web by the methods of metering roller application or pad mangle application, to be selected and changed-over at will. Elements of one application mode are also used, with other functions, for the other mode. The textile web need not be withdrawn from the apparatus and reintroduced along another path during or after change-over from one mode to the other.
Claims7
An apparatus for carrying out a process for the continuous application of liquors on textile fiber webs, comprising:
- (A) a textile web spreading and equalizing device,
- (B) a padding roller,
- (C) a combined metering roller and squeezing device downstream from the padding roller, said squeezing device comprising a tangential roller cooperating with said metering roller in a metering roller application mode, said metering roller being rotatably journaled in a pivotable liquor trough in the metering roller application mode, said tangential roller being retracted and said pivotable trough being pivoted in a pad mangle application mode, and
- (D) a counter-roller being mounted above said metering roller and pressed against the metering roller in the pad mangle application mode, and wherein said metering roller is a lower squeezing roller and, together with said counter-roller, forms a squeezing device.
An apparatus for carrying out a process for the continuous application of liquors on textile fiber webs, comprising:
- (A) a textile web spreading and equalizing device;
- (B) a padding roller for use in a pad mangle application mode;
- (C) a metering roller application device downstream from said padding roller, said metering roller application device comprising a metering roller;
- and
- (D) a pad mangle squeezing device, said pad mangle squeezing device being constructed as a double-acting squeezing device, said double-acting squeezing device comprising:
- (1) said metering roller;
- (2) a counter roller;
- and
- (3) a press roller, said press roller having a diameter which is greater than the distance between said metering roller and said counter-roller, said press roller being adapted to be pressed against both said metering roller and said counter-roller, and said press roller being adapted to be retracted to a position free from contact with said metering roller and said counter-roller.
