In a full-width washing machine for a steam-permeable textile width of fabric, an injection device for steam is provided on one side the width of fabric, and on the other side, opposite this device, a suction device is provided, which can generate a partial vacuum of at least 0.2 bar. The exit opening of the injection device and the entry opening of the suction device extend over the entire width of the width of fabric. The width of fabric is guided through and between the injection device and the suction device. Steam is injected into the width of fabric and driven through the width of fabric and extracted on the other side, together with the residues which have been dissolved out of the fabric.

In a steamer for the steaming of a web of textile material laden with liquid supplied by an applicator device, steam is continuously fed to the steamer. The quantity of steam fed to the steamer is calculated in dependence upon the amount of liquid previously applied to the web and accurately corresponds to the amount of steam necessary in order to heat the web of material to the steaming temperature.

A device for applying a treatment liquid to a moving web of material such as a textile web includes a drum that is rotatable around a horizontal axis. At least one guide roller is provided for guiding the fabric web such that the web wraps at least partially around the drum beginning at a side of the drum at which the web is disposed tangentially thereto and continuing around a bottom portion of the drum. A trailing, continuous band is also provided which is closed in a liquid-tight manner and circulates in a plane that is perpendicular to the axis of the drum. The band has an outer circumferential surface that fits closely on the fabric web at a location in which the web contacts the drum. The circumferential surface of the band and drum define a nip therebetween. The band seals off the nip at its bottom. The band has web segments forming lateral sealing elements which extend from the edges of the band to project outwardly. The segments have a side abutting a contact surface formed at the rim of the drum. The segments, which also extend in a direction perpendicular to the axis of the drum, axially seal off the nip. A feed device is provided for supplying treatment liquid to maintain a predetermined filling level of treatment liquid in the nip.

A washing unit includes several individual washing machines that adjoin the ager of a continuous bleaching installation. The washing machines immediately following the ager are operated in a co-current flow manner and receive between 10%-50% of the washing liquor conveyed through the remaining washing machines, which are operated in a counter-flow manner.
摘要:
The inner wall of the ceiling of a steam-filled treatment chamber is made of plastic and has a relief structure with peaks that face the treatment chamber. The spacing between the peaks is smaller than the normal drop diameter, i.e., is smaller than 1 mm. On the side of the inner wall of the ceiling facing away from the treatment chamber, an air gap is provided and maintained by distance pieces. A heat-insulation layer is arranged outside of the air gap.

In a double-belt press used to produce wood chip boards and the like, narrow edge strips of the filling are vacuumed off at the edge (32) of the filling (33) producing the boards (33), leaving tabs (37) in place. (FIG. 5 ).

An inductive coil for heating a rotating roller is embedded in a plastic carrier. To cool the plastic carrier in the region of the coil, a cooling element in the form of a flat cooling chamber through which a fluid cooling medium can flow is provided on the front surface of the plastic carrier facing the roller periphery.

A driven, deflection-controlled cylinder includes a stationary crosshead that is surrounded by a hollow cylinder. The hollow cylinder has a projection that includes a bushing-like part which encloses the narrow end of the crosshead with a slight radial distance therebetween. A bearing is arranged on the bushing-like part, which is supported in the axially outer part of a bearing bell that is arranged on the outer end of the crosshead. A gear wheel is arranged between the bearing bell and the end of the hollow cylinder, and it engages with a drive pinion in a drive housing. The drive housing is mounted on the side of the projection adjacent to the hollow cylinder, as well as on the outside of the axially outer part of the bearing bell that is opposite the drive pinion.

A sealing arrangement for a roll having a rotationally stationary crosshead extending through a rotatable hollow cylinder which forms an outer working circumference, includes longitudinal and transverse end seals disposed against the inner circumference of the hollow cylinder. The seals form at least one longitudinal chamber in the annular clearance space between the crosshead and hollow cylinder. The longitudinal chamber may be filled with pressure liquid for supporting the hollow cylinder. Each longitudinal seal in the form of a seal strip having a substantially L-shaped transverse cross-section with the shorter leg thereof directed against the inner circumferential surface of the hollow cylinder. The shorter leg includes a contact pressure relief surface facing the inner circumferential surface and spaced therefrom. The relief surface is in fluid communication with the pressure fluid in the longitudinal chamber and oriented so that pressure in the longitudinal chamber exerted on the pressure relief surface reduces the contact pressure between the longitudinal seal and the hollow cylinder.
摘要:
In a double-band or similar press the pressure on the mat that is being fed in is increased so rapidly as soon as this mat comes into contact with the heat-transfer surfaces that the outer areas of the mat harden under the great pressure, whereas the heat has still not penetrated into the interior of the mat. This results in an enhancement of the surface quality of the panel. As an example, to this end, a roller gap can be provided before the feed gap.
