    摘要： The invention relates to a slitter-winder for fiber webs, which comprises an unwinding section (10), a slitting section (20) and a winding section (30). The slitter-winder is configured to unwind, slit and wind a thick fiber web to customer rolls (33). The thick fiber web has basic weight of at least 200 g/m2.The unwinding section (10) of the slitter-winder comprises a first unwinder (11) and a second unwinder (12) for unwinding the thick fiber web of from a parent roll comprising full-width thick fiber web (W11, W12), and a joining device (16, 17) for joining a beginning end of a thick fiber web (W11) coming from a parent roll in the first unwinder to an end of a thick fiber web (W12) coming from a parent roll in the second unwinder by forming a joint (J), and the winding section (30) of the slitter-winder comprises a cutting device (35) for cutting and removing part/-s of the thick fiber web comprising the joint (J) from the winding section (30).

    摘要： The invention relates to a hoisting accessory (10) for a blower (12) of a pulp dryer (100), which hoisting accessory (10) includes:
    - a hoisting element (14) for fastening the hoisting accessory (10) to the blower (12) to be hoisted, and
    - first fastening devices (16) for locking the hoisting element (14) to the blower (12) for the duration of hoisting,
    - a guideway (18) comprising a first end (20) and second end (22),
    - a carriage (24) adapted on the guideway (18) for transferring a blower (12) on the guideway (18) while said hoisting element (14) is suspended from said carriage (24),
    - a support device (28) connected to said guideway (18) for suspending the hoisting accessory (10) from a second blower (13) so that said guideway (18) is supported essentially in the horizontal direction by means of the support device (28).
    The invention also relates to a method for transferring a blower (12) of a pulp dryer (100) from the pulp dryer (100) by means of the hoisting accessory (10).

    摘要： The invention relates to a suction roll (30), which comprises a rotatable outer shell (31), which has a plurality of openings (32) arranged spaced apart along the circumference of the outer shell (31), and an inside the rotatable outer shell (31) arranged in axial direction of the suction roll (30) extending stationary suction box (33), which comprises two side walls and a lower wall extending between the side walls, and a setup of seals (34, 35) configured to seal the suction box (33) against inner surface of the rotatable outer shell (31) by the seals (34, 35) of the seal setup, which seals (34, 35) are by lubrication medium lubricated seals and extend in axial direction of the suction roll (30) and are located on the side walls of the suction box (33) at edges of the side walls pointing towards the inner surface of the rotatable outer shell (31) of the suction roll (30). The outer shell (31) of the suction roll (30) is rotatable in both rotation directions (S30) and that the seals (34, 35) are similar and located in the seal setup as mirror images to each other. The invention also relates to a seal setup of a suction roll.
