Device for the wet treatment of material lengths in several treatment bowls

A device for the wet treatment of material lenghts which comprises means for wetting the material length with a treatment liquid;

• means for plaiting said wetted material length into a folded state;
• a plain steeping bowl through which the material passes slowly and in said folded state through a treatment liquid, said plain steeping bowl including a J-box positioned within a container, said J-box having a knee portion, a long intake leg portion, and a delivery leg portion, the knee portion being located in said container which is filled with said treatment liquid up to a certain level and said J-box having upper and lower walls which are surrounded by the container with the clearance between the walls initially being constant and the walls being liquid-permeable;
• said plaiting means being arranged above said long intake leg portion to plait the material length into said intake leg portion in folds which completely fill the clearance between the upper and lower J-box walls whereby a certain height of material and consequently a certain weight of material is placed in the folded state within said J-box so that the weight of material is sufficient that the material is automatically pushed through the knee portion of the J-box and out above the liquid level in the delivery leg portion to a dripping height;
• the upper wall of said J-box and at least the knee portion consisting of a plurality of guide rods which are oriented in the direction of the material passage through the J-box and mounted at a certain distance from each other, and at least one portion of the upper wall of the J-box at the knee portion being swivelable about a hinge which extends parallel to the width of the material length being treated, said hinge being located on the upper wall of said J-box;
• and a drawoff roller positioned immediately above the delivery leg portion of said J-box for receiving the material length therefrom.

A device for the wet treatment of material lengths which comprises means for wetting the material length with a treatment liquid;

• first means for plaiting said wetting material length into a folded state;
• a first plain steeping bowl through which the material passes slowly and in said folded state through a treatment liquid;
• means for squeezing the material length delivered from said first plain steeping bowl to remove excess treatment liquid therefrom, means for draining the treatment liquid squeezed from said material length;
• at least one high efficiency wash bowl arranged behind said first plain steeping bowl wherein said material length is rinsed with a treatment liquid;
• second means for again wetting the material length with a treatment liquid;
• second means for plaiting said wetted material length into a folded state;
• a second plain steeping bowl through which the material passes slowly and in said folded state through a treatment liquid;
• second means for squeezing the material length delivered from said second plain steeping bowl;
• and at least one additional high efficiency wash bowl arranged behind said second plain steeping bowl;
• each plain steeping bowl including a J-box positioned within a container, said J-box having a knee portion, a long intake leg portion and a delivery leg portion, the knee portion being located in said container which is filled with a treatment liquid to a certain level and said J-box having upper and lower walls surrounded by the container which are liquid permeable;
• each plaiting means being arranged above the long intake leg portion of a J-box to plait the material length into said intake leg portion in folds between said upper and lower J-box walls and each high efficiency wash bowl comprising a perforated drum wash bowl.

A device for the wet treatment of material lengths, which comprises several treatment bowls containing treatment liquids one of which is designed as a high efficiency wash bowl with a bowl preceding said high efficiency wash bowl serving as a plain steeping bowl through which the material passes slowly and in a folded state through a treatment liquid;

• a perforated drum wash bowl being used as the high efficiency wash bowl and a J-box positioned within another bowl being employed as s steeping bowl;
• said J-box having a knee portion, a long intake leg portion, and a delivery leg portion, the knee portion being located in said another bowl whcih is filled with a treatment liquid up to a certain level;
• said J-box also having upper and lower curved walls which are surrounded by the another bowl and the clearance between the walls being constant with said curved walls also being liquid-permeable;
• means being provided for wetting the material length with liquid located in front of a means for plaiting said material;
• said plaiting means acting to plait the material length into the long intake leg of the J-box in folds which completely fill the clearance between the upper and lower J-box walls, until a certain height of material is reached and consequently a certain weight of material pile has been achieved, the weight being sufficient so that the resulting material pile is automatically pushed through the knee portion of the J-box and out above the liquid level in the delivery leg to a dripping height;
• and a drawoff roller installed immediately above at an opening for material delivery from the J-box;
• said means for wetting the material length including a spraying assembly arranged in front of the plaiting means with fresh water pipes arranged to spray liquid onto both sides of the material length and a drain socket which is directly connected with a waste water channel.

A device for the wet treatment of material lengths which comprises means for wetting the material length with a treatment liquid;

• means for plaiting said wetted material length into a folded state;
• a plain steeping bowl through which the material passes slowly and in said folded state through a treatment liquid, said plain steeping bowl including a J-box positioned within a container, said J-box having a knee portion, the knee portion being located in said container which is filled with said treatment liquid up to a certain level and said J-box having upper and lower walls which are surrounded by the container with the clearance between the walls initially being constant and the walls being liquid-permeable;
• said plaiting means being arranged above said long intake leg portion to plait the material length into said intake leg portion in folds which completely fill the clearance between the upper and lower J-box walls whereby a certain height of material and consequently a certain weight of material is placed in the folded state within said J-box so that the weight of material is sufficient that the material is automatically pushed through the knee portion of the J-box and out above the liquid level in the delivery leg portion to a dripping height;
• the upper wall of said J-box and at least the knee portion consisting of a plurality of guide rods which are oriented in the direction of the material passage through the J-box and mounted at a certain distance from each other, whereby the material passing through said J-box can be observed and guidance of said material in a folded state can be influenced by an operator.
