  • Patent number: 6779652
    Abstract: A chain link (10) of a curved conveyor chain has been proposed, which has a carrying device (12) for transport material. A head part (24) disposed under the carrying device (12) has a lateral bore (40) for a pin (48) of a first adjacent chain link (10). The head part (24) is adjoined by a fork-shaped section (26) with two legs (44), which encompass the head part (24) of a second adjacent chain link (10). The legs (44) and contain lateral bores (46). A pin (48) is also provided, which is contained in the lateral bores (46) of the legs (44) and in the head part (24) of the second adjacent chain link (10). Projections (52) protrude from the legs (44) and are designed to be guided in a guide profile and driven by means of a driving wheel. The object of the invention is to produce a chain link (10), which permits a favorable introduction of force.

  • Patent number: 6644211
    Abstract: A deviating device for deviating a transporting means in a deviating plane was a deviating unit, two track portions of a movement path of a transporting means adjoining the deviating device and clamping the deviating plane, and mountable on the deviating unit, the track portions being mountable on a separate component of the deviating device, the components being turnable relative to one another about a turning axis which is substantially orthogonal to the deviating plane and being fixable in a predetermined angular position.

  • Publication number: 20020148706
    Abstract: A continuous conveyor for conveying material, has a supporting profile, a pulling element, a plate-shaped supporting element connected with the pulling element, at least one guiding rail for guiding the pulling element, the supporting profile being formed so that the pulling element extends in an inner region of the supporting profile, the guiding rail being arranged in the inner region of the supporting profile and guiding a lower region of the pulling element.
