Abstract: The invention relates to an extended-nip roll press for dewatering a fibrous web in a press nip which, on one side, is formed by a rotating mating roll and, on the other side, is formed by an extended-nip press roll, whose roll centers lie in a stack plane, and the extended-nip press roll has a stationary support and a flexible roll cover that can rotate about the support, the cover in the region of the press nip being supported on the support on a sliding surface which is formed on an upper part, defining an entry and exit, of a press shoe that can be displaced with respect to the support in a loading direction, it being possible for the press shoe to be displaced radially along a loading plane which intersects the stack plane at the center of the mating roll and at an acute angle to the exit direction.

Abstract: A device for processing a continuously running strip of material includes an ultrasonic generator unit with a sonotrode that is fixed opposite a counter roller. The material strip is processed in the gap. To adjust the gap height, the force in the gap is measured using a force measuring member, and used for regulation.

Abstract: A calender arrangement includes end rolls that are in the form of deflection controlled rolls having an internal stroke. One of the end rolls comprises at least one stop element that is in the form of a hydraulic positioned hydrostatic element which, together with the internal wall of the roll sleeve, defines a gap. When a constant throughput of hydraulic medium is fed in, an equilibrium of forces is produced, at which equilibrium the roll sleeve is positioned. The pressure built up in the process is a measure of the positioning forces. Small departures from the target position are permitted without control intervention.

Abstract: In a spiral steamer, the deflecting rollers are arranged in the lower areas of the individual windings of the spiral in such a way that the fabric web approximately follows a chain line.

Abstract: A calender for treatment of a web of a nonwoven textile V made of thermoplastic fibers. The calendar includes a heated embossing roller made of steel and a counter-roller that runs at the same circumference velocity. The local plastification in the nonwoven textile V that is produced at the locations of the raised embossing areas results in a board-like feel of the nonwoven textile V. To reduce this hardness, the web of the nonwoven textile V is broken, after having cooled at least partially.

Abstract: A device for treating a continuously advancing material web with ultrasound includes an ultrasound generator and a sonotrode, rigidly connected with the former in a manner so as to transmit ultrasound. The sonotrode has a face which lies opposite a counter-tool. The material web is passed through the gap. The module composed of the ultrasound generator and the sonotrode is connected with the machine frame via a piezoelectric actuator, by means of which small displacements of the face of the sonotrode relative to the circumference surface of the counter-roller can be balanced out.

Abstract: The device (100) is used to apply a treatment medium to a moving strip of material (W) e.g. a dyebath to a strip of carpet. The device (100) is composed of a rigid support (3) that is securely arranged in a machine frame (1) and extends in a perpendicular position with respect to the strip of material, an inflatable pressure cushion (12) extending along the support (3), a less rigid supporting beam (13) arranged on the pressure cushion (12) with ends that are mounted in an articulating manner on the machine frame (1) around axes (22, 22) that are parallel to the strip of material, in addition to an application beam (25) placed on the supporting beam (13) in perpendicular position with respect to the strip of material (W) and running parallel to the surfaces thereof, whereby the application beam rests upon the strip of material (W) with the aid of a sliding surface. An application slit (30) that opens out onto the sliding surface (35) in placed in the vicinity thereof.

Abstract: A device for applying a patterning liquid to a web, particularly to a carpet web, has an exit slit with a plurality of valves distributed over the width of the web and arranged ahead of it, which can all be activated independent of one another, and which each supply the patterning liquid to a specific width section of the application slit. The valves are located as close as possible to the exit location so that the segment from the closing location of the valves to the exit location is as short as possible.

Abstract: A tubular element (100) which is inserted into a liquid-conducting conduit (10) includes an annular chamber (25) that is delimited radially towards the inside by a tubing section (30) made of a material with an elastically flexible surface. The tubular element (100) serves as a flexible damping conduit section, or, if the annular chamber (25) is connected with a partial vacuum chamber at a connector (21), and the tubing section (30) is inflated into the annular chamber (25), as a means for temporarily holding an amount of liquid, for example in order to withdraw a dye bath from the exit slit of an application device for dyeing textile webs.

Abstract: The treatment device includes a container for a treatment fluid, in which a drum around which the web loops rotates eccentrically. The drum is made up of axis-parallel, hollow, sealed rods and possesses a drum shaft structured as a hollow shaft, which together produce a buoyancy which makes up a significant part of the weight of the drum and the drum shaft. The drum is suspended at one end via stretchably elastic drive belts, and at the other end on tension springs, which catch the remaining weight. The drum shaft is eccentrically mounted on an eccentric shaft. The eccentric shaft is provided with equalization weights. All of the measures act together to allow low-vibration operation, towards the outside, of the treatment device.

Abstract: A valve arrangement for fluid media, with a plurality of valves (50), which are arranged in a common housing (20). Each valve has at least two feeds (57, 58) and an outlet channel (54), with all the outlet channels (54) emptying into a common outlet zone (11). An example of use is a patterning device for webs (10) of carpeting, where the common valve housing (20) is an application bar, and the outlet zone (11) is a narrow application slit, from which the patterning agent (dye bath) which forms the fluid medium is transferred directly to the web (10) from the application slit.

Abstract: A process for dyeing a textile web, in which the textile web is continuously guided through a trough that contains the dye bath, and subsequently passes through a pair of squeezing rollers. The line force of the pair of squeezing rollers is adjusted as a function of the length of textile web (L) that has passed through, with the aim of achieving a uniform amount of dye applied over the length of the textile web, per surface unit of the textile web.

A guide roller which extends parallel to the axis of the winding roller over the width of the textile web, and rests against the fabric roll which forms on the winding roller, from the bottom, is provided, and has openings on its otherwise cylindrical circumference, which are arranged so as to avoid zones without openings which run in the circumference direction, and are uniformly distributed over the circumference.

Abstract: A calender which includes a deflection-controlled roller with a rotating hollow cylinder and a non-rotating cross-head. Hydrostatic supporting elements on the cross-head can be radially displaced towards the inside circumference of the hollow cylinder, and have hydrostatic bearing pockets in their contact surfaces. The position of supporting elements are controlled using a cylinder space with a small cross-section. When there is a problem with the web, the cylinder spaces can all be hydraulically relieved, eliminating the contact pressure and therefore the exertion of force by the supporting elements.

Abstract: A process and a system for dyeing a textile web according to the cold-pad batch process includes a device for defined application of a dye liquor to the textile web and a winding device for rolling the textile web provided with the dye liquor onto a fabric roll. On the winding device, a supply roll with a plastic film web is mounted, which can be wound around the finished fabric roll in a wrap, using the same winding device. The end of the wrap is sealed together with the plastic film web and the plastic film web is cut off. In this way, it is easier to wrap the fabric roll, as is necessary for several hours of dwell time on the fabric roll.
