| 141 | Process for drying paper webs | US313136 | 1994-12-15 | US5556511A | 1996-09-17 | Reinhard Bluhm; Thomas Gotz |
| Process and device for drying paper webs, with the process being utilized for drying voluminous paper webs, destined in particular for use as toilet paper, with at least one heated press being used for drying the wet paper web, with the undesirable delamination of the paper web, when it leaves the compression gap, caused by the sudden expansion of the flash steam, being purposefully used in order to improve the volume and softness of the thus produced paper. Several devices are also set forth for implementing the process, these devices having both short and elongate compression gaps. | ||||||
| 142 | Heavy-weight high-temperature pressing apparatus | US195522 | 1994-02-14 | US5439559A | 1995-08-08 | Jere W. Crouse |
| An extended nip press has a heated backing roll, on the surface of which a paper web is preheated before it passes through the extended nip. The paper web is restrained on the surface of the backing roll to achieve post-pressing drying. During a portion of the post-pressing drying, the extended nip press may be arranged so that the paper web is not backed by the pressing/drying felt, thus allowing free venting from the web to occur. In some cases, this zone will be augmented by a vacuum assist unit to draw steam away. This high temperature press is capable of outgoing dryness in the range of sixty-five percent versus fifty percent for conventional technology. This combination of high temperature pressing and drying can be expected to improve the maximum strength of the web by approximately 20 percent or more over conventional pressing methods. Two high temperature press dryers of this invention may be combined to achieve outgoing dryness of approximately seventy percent. | ||||||
| 143 | Method and device for intensifying the operation of a Yankee press in a soft-tissue paper machine | US73101 | 1993-06-07 | US5385644A | 1995-01-31 | Lars H. M. Hannus; Jens P. Enkvist |
| A method and device for intensifying the operation of a Yankee press in a soft-tissue machine in which a web is pressed in one or several nips formed between a Yankee cylinder and one or more press rolls. The web is dried on the Yankee cylinder by blowing hot air introduced through the Yankee hood against the web. In the method, a blow device is used to blow hot and humid air against the web. The blow air for the blow device is taken from the outlet/heat recovery of the air system of the Yankee hood, and the exhaust air from the blow device is returned to the outlet/heat recovery of the air system of the Yankee hood. Air is blown against the web at the proximity of the nip formed between the Yankee cylinder and the first press roll, before and near the first press nip, in the running direction of the web. The blow device includes a blow chamber, an exhaust chamber, and blow nozzles for blowing hot and humid air against the web and exhaust-air ducts for the removal of the air. | ||||||

| 145 | Method for the mechanical-thermal dewatering of a fiber stock web | US469071 | 1990-01-23 | US5071513A | 1991-12-10 | Reinhard Bluhm; Herbert Holik; Peter Mirsberger |
| At least two substantially parallel rows of adjustable pressure elements cooperate with a heatable counter element like a counter roll and are arranged immediately consecutive but separate from each other to define at least two pressing sections of an extended pressing zone through which a water-containing fibrous web is passed conjointly with a water absorbing porous band or felt in a predeterminate travel direction. Pressures and temperatures in each one of the at least two pressing sections of the extended pressing zone are adjusted such that water is displaced from the fibrous web under the combined action of pressure and steam which is formed in the extended pressing zone in a controlled manner and without damage to the fibrous web due to explosion-like flash evaporation. | ||||||
| 146 | Apparatus for forming, pressing and drying paper webs having a felt and web run to a Yankee cylinder | US235749 | 1988-08-22 | US4911791A | 1990-03-27 | Kurt Mokvist |
| A machine for producing thin paper web at high speed comprises a forming section (often called a twin wire former), a web transfer section (in which the formed sheet is transferred to the press felt), and a press roll over which the press felt with the web is turned so that the web presses against the warm Yankee cylinder, the web being formed between a felt--or a press fabric (2)--and a forming fabric (3). The forming unit, consisting of the felt and fabric, is placed in such a position in relation to the press roll (8) that the web (10), when separated from the forming fabric (3), is transproted on the top side of the felt (2) into a press nip against a Yankee cylinder (7) surface along a straight path tangentially to the Yankee cylinder surface. | ||||||
| 147 | High heat flux roll and press utilizing same | US181100 | 1988-04-13 | US4889048A | 1989-12-26 | Ray R. Miller |
| The disclosure describes a drum or roll which may be heated to high operating temperatures and is particularly useful in situations where a high heat flux is required under conditions of high nip and distributed loads on the drum. It consists of a relatively thin rotating shell supported on an axially located stationary inner core. The core has a plurality of shell support bearings. These have close radial clearances with the inner surface of the shell at each location where an extrnal nip roll would be engaged. The spaces between the shell support bearings form pressurizable chambers. These chambers can be filled with a hot pressurized fluid for supporting the shell between the supports located at the nip positions. In one application the roll would be used as the drum in a belt and drum press having high nip loads at several locations and high distributed loads applied by a tensioned belt. The fluid support system for the rotatable shell enables a very thin shell to be used. This permits the desired heat flux while still maintaining the mechanical integrity to support the applied loads. Operating temperatures of the roll could range up to 800.degree. F. with multiple nip loads typically being up to 1000 to 2000 pounds per linear inch and 100-800 psi unit pressure, and with distributed loads between the nips of up to 50 psi. High thermal conductivity materials such as copper or aluminum may be used as shell material to reduce temperature differential and thermal stress. | ||||||
| 148 | Belt and drum-type press | US849931 | 1986-04-08 | US4710271A | 1987-12-01 | Ray R. Miller |
| A press belt arrangement in which none of the compressive forces on the central drum are transmitted to the supporting frame. It provides a method in which a greater compressive force in relationship to belt tension is applied to the drum. The invention makes it possible to construct the central drum so that large quantities of heat can be fluxed through it for purposes of achieving the fast drying rates long sought in the industry. | ||||||
| 149 | Methods and apparatus for the rapid consolidation of moist porous webs | US158080 | 1980-06-10 | US4324613A | 1982-04-13 | Douglas Wahren |
| A moist, porous web is consolidated and dried by running it through the nip between two rotatable rolls, the surface of one of which is heated as it approaches the nip. One side of the web is in direct contact with the surface of the heated roll and the other side faces a permeable surface. The rolls are pressed together under high pressure to transfer heat from the heated roll to the web compressed therebetween to dry the same. The roll surface may be heated by hot gases from a fuel combustion burner or by a liquid medium. The dried and consolidated web may be removed from the heated roll by doctoring or it may be conveyed from the nip between the rolls to apparatus for processing it further. | ||||||
| 150 | Method of and apparatus for making imprinted paper | US116429 | 1980-01-29 | US4302282A | 1981-11-24 | Terrill A. Young |
| An improved method of making imprinted paper on a Yankee dryer type papermaking machine wherein a substantial length portion of a loop of imprinting fabric post-wraps an arcuate sector of the Yankee dryer immediately after a pressure roll-Yankee dryer nip, and by being tensioned imposes radially inwardly acting compressive loading on a corresponding length portion of the web disposed between the fabric and the dryer surface. This enables, for instance, improved Yankee dryer speed, improved web tension and edge control of the paper when creped off the Yankee dryer, reduced use of adhesive on the Yankee dryer surface, improved fiber transfer efficiency, and reduced energy consumption per ton of paper made. | ||||||

The web is adhered to the Yankee cylinder and the Yankee felt is detached from the web, passed around separate rolls and returned to the web on the Yankee cylinder in a third nip which in which adherance of the web to the Yankee cylinder is assured. | ||||||
| 152 | Paper machine with single-wire and curved twin-wire formers | US723225 | 1976-09-15 | US4055461A | 1977-10-25 | Risto Turunen |
| A paper machine, particularly adapted for manufacturing tissue paper, has inner and outer endless fabrics, each in the form of a wire or felt, guided around a smooth forming roll where the inner fabric is situated next to the forming roll between the latter and the outer fabric to define at the forming roll a curved twin-wire former. The outer fabric has an elongated portion situated in advance of the twin-wire former and spaced from the inner fabric to form a single-wire former which receives stock from a headbox and with which a suitable dewatering structure cooperates so that a considerable amount of water has been removed from the web forming on the single-wire former by the time the web reaches the twin-wire former. At the end of the twin-wire former distant from the single-wire former, the inner and outer fabrics are separated from each other and the web is transferred to the inner fabric by way of the normal table roll effect between the inner fabric and the smooth forming roll. At a part of the inner fabric which is distant from the smooth forming roll there is a pick-up structure for picking up the web from the inner fabric and directing the web to the press and dryer sections of the machine. | ||||||
