摘要： The twin-wire former serves for the production of a web of paper or board. Two wire belts (endless wire loops 11 and 12) form a twin-wire zone with each other. Within the twin-wire zone, the one wire belt (12) travels over rigid ledges (28', 28) which are arranged spaced apart from each other on a water-removal box (18). Within the twin-wire zone, furthermore, the other wire belt (11) travels over several ledges (27) which lie opposite the rigid ledges (28), are supported by means of resilient elements (springs 24, pneumatic pressure cushions, or the like), and can be pressed with a selectable force against the other wire belt. Within one of the wire loops (for instance 11), bridging at least two of the ledges (27) present there, a closed wire support surface (9) is provided. A secondary headbox (10') can be arranged in front of the closed wire support surface (9).

摘要： Various embodiments of a press section for a paper making machine are disclosed having a first press section with two press nips defined by press rolls pressing against a first central roll followed by a second press section with two press nips defined by press rolls pressing against a second central roll. The first central roll is wrapped by a first felt which carries the web through the first and second press nips. The second central roll is unfelted. At least a single respective felt passes through each of the four press nips, and in some embodiments two felts pass through some of those press nips. At least one of the third and fourth press nips is defined by a long nip shoe press in the respective press roll. An additional press nip may be defined around either of the last press roll of the first press section or the first press section, and that additional press nip is double felted. The transfer between the first and second press sections may be an open transfer from the second press roll of the first section or it may be a supported transfer by the felt passing through the second press nip carrying the web into the third press nip.
摘要翻译：公开了一种用于造纸机的压榨部分的各种实施例，其具有第一压榨部分，其中两个压榨辊隙由压榨辊限定，压榨辊压靠第一中心辊，随后是第二压榨部分，两个压榨辊隙由压榨辊压制而成，中央卷。第一个中央卷筒被第一个毡包裹，第一个毛毯通过第一个和第二个压榨辊子将纤维网带到纸上。第二个中央卷是没有弹性的。至少单个相应的毛毡穿过四个压榨夹中的每一个，并且在一些实施例中，两根毛毡通过那些压榨压片中的一些。第三和第四压榨辊隙中的至少一个由相应的压辊中的长辊隙压榨机限定。可以围绕第一压榨部或第一压榨部的最后一个压榨辊中的任一个限定另外的压榨压区，并且另外的压榨压区是双重毡。第一和第二挤压部分之间的转移可以是从第一部分的第二压榨辊的开放转移，或者可以是通过毛毡穿过带有纸幅的第二压榨压区进入第三压榨压区的支撑转印。
