  • Patent number: 4907697
    Abstract: A container (1) for transporting, for example, the rolls of papermaking machines comprises an outer supporting rigid metal frame (3) and a nonsupporting casing (4) protecting the roll, said metal frame comprising an end frame member (5) at each short end of the container, and a side frame member (6) arranged along each of the container long sides and connected to said end frame members (5). The frame is preferably provided with lifting lugs (10) and recesses (8) for the fork arms of a fork-lift truck or the like. The casing comprises a semicylindrical bottom part (14) and one or more top parts (15) which also are semicylindrical and detachably connected to said bottom part (14).

  • Patent number: 4872495
    Abstract: A tool for rotation ring type barking machines comprises a swinging arm which is connected at one end via a screw connection with a holder on a shaft rotatably mounted in the rotor of the machine. The holder has two elongated grooves spaced apart by an intermediate ridge and adapted to accommodate two spaced-apart beads formed on the swinging arm. The two outer lateral faces defining the grooves are sloping in cross-section and converge toward one another at an angle slightly less than a corresponding angle of convergence between the outer lateral faces defining said beads. Also the inner lateral faces of said beads and said ridge are sloping, and upon tightening of the screw connection at issue the beads are urged into the two grooves, the difference between said angles of convergence being gradually reduced toward zero until the inner bead faces come into contact with the lateral faces of the ridge, at which point the screw has been tightened with sufficient tensioning force.

  • Patent number: 4865095
    Abstract: A tool for rotation ring type barking machines comprises a curved swinging arm which is adapted to carry at a first, free end a cutting edge and which is detachably connected at its opposite end by means of a screw connection with a shaft rotatably mounted in the rotor of the machine, more particularly via a holder which is preferably made in one piece with the shaft and extends at an angle relative to said shaft. The swinging arm is displaceably movable relative to the holder and fixable by means of said screw connection in different selectable positions relative thereto, in order to permit variation of the distance between the center of the pivot shaft and the center of gravity of the swinging arm.
