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.

Abstract: A widening device for increasing the width of a moving web of material comprises a rotatable profiled roller, the outer surface of which defines a plurality of radial projections and recesses distributed along the length of the roller and first and second co-operating rollers rotatable at the same speed as the profiled roller. The first and second co-operating rollers define projections and recesses complementary to those of profiled roller and define first and second treatment nips which serve to increase the width of a web of material passed therethrough. The projections on the co-operating roller defining the second treatment nip extend more deeply into the recesses of the profiled roller than do the projections on the co-operating roller which defines the first treatment nip so that the web of material is stretched gradually over two stages with the stretching effect being uniform across the entire width of the web.

Abstract: A method for manufacturing a laminate material for use as a surface covering or the like, by reusing plastic trimmings, includes the step of forming a layer from the plastic trimmings, and preferably subjecting both sides to a surface compression while simultaneously providing heat transfer, thus allowing the zones near the surface to be melted on.

Abstract: 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.

Abstract: 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.

Abstract: A device for continuously treating a textile fabric web comprises at least one application devices for applying one or more treatment liquors to the fabric web. After applying the liquors, the fabric web exhibits a total moisture content in the range of 100 to 220% of the weight of the dry fabric. The fabric web with the moisture is fed into a tower-like heating zone of an ager, in which the fabric web is guided over a path consisting of a plurality of horizontal loops.

Abstract: 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.

Abstract: 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.

Abstract: 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 ).

Abstract: 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.

Abstract: Described is a drain board (100) for a device for applying a liquid film to a web (8) of textile material. The drain board (100) comprises a support (1), on which a strip (10), which constitutes the draining surface (A) and is made of planar material is held flat, for example by magnets (3), by means of a vacuum or by a contact adhesive. The liquid is poured out at point (4) on to the draining surface (A); it flows down and falls off the lower edge (6) of the strip (10) in a falling film (7) or veil on to the fabric web (8). As a result of the magnetic retention, the strip cannot be replaced (FIG. 1).

Abstract: In a double belt press, in which the steel belts are supported on the back by rollers, inherent compressive stress occurs on the side of the steel belts of a double belt press that are supported on the back by rollers, resulting in an undesirable bowl-shaped deformation of the steel belts. In order to avoid this deformation, at least the side of the steel belts which faces away from the rollers is subjected to treatment by shot blasting before being installed in the double belt press.

Abstract: An undyed carpet web is pretreated by applying a liquid preparatory agent in a gap of an applicator. Subsequent to the application of the preparatory agent, the carpet web is detained in a dwell apparatus. The web is then suctioned off in a hydroextraction device and steamed in a steaming machine before the dyeing operation begins.

Abstract: A roller for compressing of webs of material comprises a rotating hollow roller traversed lengthwise by a stationary crosshead. Hydraulic loading devices in the form of sealing members act on the inside circumference of the hollow roller and delimit hydrostatic bearing pockets to which hydraulic pressure fluid can be supplied. The extension of the sealing members is limited by head bolts, which make it possible to position the hollow roller relative to the crosshead during operation.

Abstract: 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.

Abstract: A roll with a revolving hollow cylinder which forms the working roll circumference, and a stationary crosshead penetrating said hollow cylinder lengthwise and leaving clearance all around to the inner circumference of the hollow cylinder in which the hollow cylinder can shift radially as a whole, e.g., can drop under its own weight on to the top side of the crosshead. A damping element is provided to damp this sinking movement before contact is made. It features a piston which plunges into a cylinder filled with hydraulic fluid and initially open to the top. During the plunging action, the hydraulic fluid is displaced out of the cylinder and flows away, in a throttled state, between the piston and the cylinder and/or through especially provided choke bores, so that the damping effect is attained.

Abstract: 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.

Abstract: In a hydraulically supported roll including a rotatable hollow cylinder and a stationary crosshead, transverse end seals are provided to seal the annular clearance space formed between the crosshead and the inner circumference of the hollow cylinder. Each transverse end seal includes a slide ring having a chamber located on the first surface of the slide ring abutting a counter-ring. The chamber provides hydraulic relief. Radially outside of the chamber a narrow groove is provided which communicates with the low-pressure side of the slide ring via a channel. The channel discharges hydraulic fluid flowing to the first surface of the slide ring as a result of the high pressure in the clearance space.

Abstract: 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.
