Abstract: A press apparatus (10) is disclosed for a paper making machine for pressing a web (12). The apparatus (10) includes a frame (14) and an extended nip module (16) which is removably connected to the frame (14). A backing roll (18) is disposed beneath the module (16) and is removably connected to the frame (14). The backing roll (18) cooperates with the module (16) for defining therebetween an elongate press nip (20) for the passage therethrough of the web (12). A felt (22) extends through the press nip (20) for receiving water ejected from the web (12) during passage of the web (12) and felt (22) therethrough. A looped bearing blanket (24) extends around the module (16), the arrangement being such that the blanket (24) is disposed between the module (16) and the felt (22) during passage of the blanket (24) through the press nip (20). A positioning device (26) is disposed above the module (16), and selectively connected to the module (16) adjacent to a first location (28). The positioning device (26), when connected to the module (16), permits movement of the module (16) away from the backing roll (18). A link device (30) selectively extends between the frame (14) and a second location (32) adjacent to the module. The first and second locations (28, 32) are spaced relative to each other. The arrangement is such that when the positioning device (26) is connected to the module (16) and in a first disposition thereof, and the link device (30) extends between the frame (14) and the second location (32), the module (16) is urged towards the backing roll (18) for defining therebetween the press nip (20). When the positioning means (26) is in the second disposition thereof, and the link device (30) extends between the frame (14) and the second location (32), the module (16) is moved away from the backing roll (18) for facilitating removal and installation of the felt (22). When the link device (30) is selectively disconnected from the second location (32) and the positioning device (26) is in a third disposition thereof, the module (16) is suspended by the positioning device (26) for facilitating removal and installation of the bearing blanket (24). When the positioning device (26) is selectively disconnected from the first location (28), removal and installation of the module (16) is facilitated. When the positioning device (26) is in the second disposition thereof, and the link device (30) extends between the frame (14) and the second location (32) with the felt (22) removed, removal and installation of the backing roll (18) is facilitated.

Abstract translation: 公开了一种用于压制卷材（12）的造纸机的压制装置（10）。 装置（10）包括框架（14）和可移除地连接到框架（14）的延伸夹持模块（16）。 背衬辊（18）设置在模块（16）下方并且可移除地连接到框架（14）。 背衬辊（18）与模块（16）配合，用于在其间限定用于纤维网（12）穿过其中的细长的压榨压区（20）。 毛毯（22）延伸穿过压榨压区（20），用于在纸幅（12）和毛毡（22）穿过其时通过从纸幅（12）喷出的水。 环形轴承覆盖层（24）围绕模块（16）延伸，该布置使得在橡皮布（24）穿过压机期间，橡皮布（24）设置在模块（16）和毛毡（22）之间。 nip（20）。 定位装置（26）设置在模块（16）上方，并且与第一位置（28）相邻地选择性地连接到模块（16）。 定位装置（26）当连接到模块（16）时允许模块（16）从支承辊（18）移动。 连接装置（30）选择性地在框架（14）和与模块相邻的第二位置（32）之间延伸。 第一和第二位置（28,32）彼此间隔开。 该布置使得当定位装置（26）连接到模块（16）并且在其第一布置中，并且连杆装置（30）在框架（14）和第二位置（32）之间延伸时， 模块（16）被推向背衬辊（18）以在其间限定压榨压区（20）。 当定位装置（26）处于其第二位置时，并且连杆装置（30）在框架（14）和第二位置（32）之间延伸时，模块（16）移动远离支承辊（18） ），用于促进毛毯（22）的移除和安装。 当链接装置（30）从第二位置（32）选择性地断开并且定位装置（26）处于第三位置时，模块（16）由定位装置（26）悬挂以便于拆卸和安装 的轴承盖（24）。 当定位装置（26）从第一位置（28）选择性地断开时，便于拆卸和安装模块（16）。 当定位装置（26）处于其第二布置中时，并且连接装置（30）在毛毯（22）被移除的情况下在框架（14）和第二位置（32）之间延伸，拆卸和安装支承辊 （18）。
