Abstract
The invention concerns a storage box A 0 (10) for doctor blades employed in servicing of the face of a roll in a paper/board machine. The box is a polygon construction, in whose interior the reel (R) formed by doctor blades (t1, t2) has been fitted. Through an opening (11) in a side face of the storage box, the doctor blades (t1, t2, . . . ) can be discharged from the reel (R) placed inside the storage box (10). In its interior, the storage box (10) comprises bearing means, preferably at least one separate disk (10a3′), which has been fitted to revolve freely on the side face of the reel (R) formed by the doctor blades.

A storage box (10) for doctor blades employed in servicing of the face of a roll in a paper or board machine, which box is a polygon construction and in whose interior the reel (R) formed by doctor blades (t1, t2) has been fitted, and from which box, through an opening (11) in a side face of the box, the doctor blades (t1, t2 . . . ) can be discharged from the reel (R) placed inside the storage box (10), wherein in the interior of the storage box (10) comprises bearing means (10a3), including a separate disk (10a3′, 10a30′), which has been fitted to revolve freely on the side face of the reel (R) formed by the doctor blades;
- wherein the bearing part (10a3′) has been fitted to be placed against a face (N) of a backup bearing part (10a3″) of the bearing means (10a3), which backup bearing part (10a3″) comprises edge parts (M1, M2 . . . ) in which connection the real (R) formed by doctor blades has been fitted in the area between edge parts (M1, M2 . . . ) and a middle area (e) of a plate part (10a3″), are the bearing part (10a3′) has been fitted between the reel (R) formed by doctor blades and the middle area (e2) of the plate part (10a3″), in which case the inner faces of the edge parts (M1, M2) form a bearing face for the circumferential face of the reel (R) of doctor blades.
A storage box (10) for doctor blades employed in servicing of the face of a roll in a paper or board machine, which box is a polygon construction and in whose interior the reel (R) formed by doctor blades (t1, t2) has been fitted, and from which box, through an opening (11) in a side face of the box, the doctor blades (t1, t2 . . . ) can be discharged from the reel (R) placed inside the storage box (10), wherein in the interior of the storage box (10) comprises bearing means (10a3), including a separate disk (10a3′, 10a30′), which has been fitted to revolve freely on the side face of the reel (R) formed by the doctor blades;
- wherein edge parts (M1, M2, M3 . . . ) of a backup bearing part (10a3″) have been folded perpendicularly to a middle area (e2) of a plate part (10a3″), and they are placed so that their end edges (I, I′) overlap each other.
A storage box for doctor blades employed in the servicing of the surface of a roll in a paper or board machine, said storage box comprising:
- a box body having polygonal construction including a bottom;
- a cover adapted to fit over the bottom;
- said box body being structured and arranged to receive a reel for discharging doctor blades;
- said box body having a slot in a perimeter thereof, said slot being structured and arranged to permit the passage of said doctor blades to thereby permit the discharge of said doctor blades from said box;
- and
- bearing means adapted to fit within said box and permitting said reel of doctor blades to revolve freely within said box,
- wherein said bearing means comprises:
- a back-up bearing part having a polygonal construction to thereby conform to the shape of said storage box, a contact surface and a plurality of edge parts extending from a perimeter of said contact surface, said edge parts being arranged perpendicularly to said contact surface thereby defining a middle area, said back-up bearing part being structured and arranged to fit within said storage box;
- and
- a first and second contact plate each having a terminal edge, first and second surfaces and each being adapted to fit within said middle area of said back-up part
- said first contact plate being structured and arranged within said back-up part, said first surface of said first contact plate contacting said reel and said second surface of said first contact plate contacting said back-up part,
- said second contact plate being structured and arranged with said back-up part, said first surface of said second contact plate contacting said reel and said second surface of said second contact plate contacting said bottom of said storage box, and
- said terminal edges of each of said first and second contact plates resting against said edge parts to thereby retain said reel of doctor blades therebetween.
