Publication number: 20040200592Abstract: A method and device for installing a belt onto a long nip press or calender of the shoe type. The belt to be installed has a number of opposing flaps on each edge for securing the belt to the press. The flaps are inserted and passed through corresponding slots spaced around the rotating head ends of the press. Positioning wedge devices are slid into position on each flap and locking pins are inserted into holes in the flaps. The wedge devices effectively lock the flaps in place by securing the locking pins. The devices precisely align and tension the flaps on the press, thereby ensuring a proper installation of the belt. Once the flaps are secured to the press, the positioning devices and locking pins are removed.Type: ApplicationFiled: April 14, 2003Publication date: October 14, 2004Inventor: Bo-Christer Aberg

Patent number: 5836242Abstract: A calendering system in a papermaking or board manufacturing process, the system comprising at least one press nip, an endless calender belt (30) having a core (32) and a compressible, elastic material bonded to the core (32), as well as a paper or paperboard web (16) which passes together with the belt (30) through the press nip and the dewatering of which is completely or at least substantially completely terminated earlier in the manufacturing process. The calender belt (30) has in its thickness direction a first hardness on the side (34) of the core (32) closest to the web (16) and a hardness on the opposite side (36) of the core (32) that is higher than the first hardness. The first hardness is so selected in relation to the web (16) that the surface (38) of the calender belt (30) engaging the web (16) can adapt its shape in the press nip (14) to unevennesses in the surface (20) of the web (16).Type: GrantFiled: December 9, 1996Date of Patent: November 17, 1998Assignee: Albany Nordiskafilt ABInventor: Bo-Christer Aberg

Patent number: 5427653Abstract: A press is devised for a papermaking machine. The press is of the type having a rotary press roll, a substantially stationary pressure shoe, and a press belt running in an endless path around the pressure shoe between this and the press roll and having a substantially impermeable inner surface facing the pressure shoe. A separate, endless reinforcing belt enclosing the press belt is in frictional engagement over the entire length of the press belt so as to run together in the press belt in the endless path. The reinforcing belt may be prestressed, e.g. by shrinkage, in its running direction and, optionally, also transversally thereof. According to a second aspect, the invention relates to a method of modifying a press of the type indicated above, in which method the press belt is enclosed by a separate, endless reinforcing belt of the above-indicated type.Type: GrantFiled: November 18, 1993Date of Patent: June 27, 1995Assignee: Albany Nord skafilt ABInventors: Nils Andersson, Bo-Christer Aberg
