Abstract: In a process for continuous grinding of web-shaped, textile flat articles by a grinding tool with a coating angle determined by a coating roller, an adjusting member acts on the coating roller to adjust a coating angle in dependence on a friction force which acts on the flat article.

Abstract: The process for continuous intensive wetting of a textile strip with a wetting fluid, e.g.

Abstract: A method of continuous permanent decating and fixing of web-shaped textile products includes the steps of moistening a textile product, treating the moistened textile product in a first moist treatment stage by guiding the moistened textile product over a rotatable and heatable cylinder and pressing against a part of a cylinder surface, subsequently moistening the textile product, then treating the textile product in a second dry stage by guiding the textile product over a rotatable and heatable cylinder and pressing it against a part of a cylinder surface so that in the first moist stage one side of the textile product is in contact with the cylinder surface of the first mentioned cylinder while in the second dry stage the other side of the textile product is in contact with the cylinder surface of the second mentioned cylinder, regulating a moisture of the textile product so that shortly before an end of the second dry treatment stage it has a normal moisture, and maintaining pressing actions in the treatme

Abstract: A process for the continuous permanent decatizing and fixing of textile materials in web form, such as woven, knitted fabrics or the like is described. In the process the textile material is damped to a range of 20 to 100%, and pressed against part of two heatable cylinders. The surface temperature of each heatable cylinder is in excess of 140.degree. C. In a first process step the left side of the textile material is applied to the first heatable cylinder, and in a second process step the right side of the textile material is applied to the second heatable cylinder.

Abstract: A fabric such as a knitted wool or wool mixture is treated by the application of a crabbing agent together with a hygroscopic substance. The fabric is then dried, sheared and moistened before passing through a decatizing apparatus in which the crabbing agent, reactivated during the moistening stage, reacts within the fabric fibers to render the changes produced during decatizing permanent.

Abstract: In a fabric treatment process, the fabric is subjected to a decatizing finishing step using a steaming and suction cylinder immediately after it has been subjected to a treatment step in which the fabric is pressed and fixed on a steaming cylinder.

Abstract: The initial moisture content of textile material to be decatized and fixed is controlled by a feedback-type regulator circuit which is responsive to measured values of the water content of vapor clouds produced as the material emerges from its passage around a steaming cylinder. The moisture content is preferably controlled by regulating the amount of water applied by a moistening device upstream of the steaming cylinder.

Abstract: In the decatizing apparatus of the present invention the fabric to be treated is fed around a rotatable, heated cylinder between a backing cloth and a tension thrust belt. The presence of the backing cloth between the surface of the cylinder and the fabric prevents the production of an excessive greasy gloss effect on the surface of the fabric closest to the cylinder. A moistening device may be provided to moisten the backing cloth before it passes around the cylinder. A wide variety of decatizing effects can be achieved by adjusting the temperature of the belt and cylinder, the tension of the belt, and the moisture content of the backing cloth and fabric.

Abstract: The cutting apparatus for cutting a moving strip of material comprises a rotating cutting cylinder having a spatially fixed nap height determining plate provided with a plurality of holes which contacts a part of the active outer circumference of the cutting cylinder. The exterior side of the plate is the bearing surface for the strip of material and the holes provide opposing cutting edges for a plurality of cutting edges of the cutting cylinder.

Abstract: A device for detecting transverse seams at the junctions of interconnected sections of fabric, paper or other sheet material, advancing continuously past a treatment station, comprises a plurality of sensors in the form of potentiometers whose sliders are provided with rollers contacting the sheet surface at transversely spaced locations which may also be relatively offset in the direction of travel. The output signals of the several potentiometers are compared in an evaluator which distinguishes actual seams from surface irregularities or from thickness variations forming part of a certain pattern. The evaluator includes signal-storing means facilitating the detection of seams deviating within given limits from a transverse line.

Abstract: A prismatic waveguide of square or rectangular cross-section has at least one pair of opposite inner wall surfaces formed with inwardly projecting parallel cheeks extending along a treatment zone for elongate polymeric workpieces, the width of the cheeks being less than the spacing of the other pair of inner wall surfaces from each other. The waveguide is split along a median parting plane, bisecting this pair of cheeks, to facilitate separation of its two halves by relative tilting about a pivotal axis, the two halves adjoining each other along quarter-wavelength flanges parallel to that plane preventing the outward leakage of microwave energy.
