Abstract
A mesh-belt conveyor for conveying materials into industrial furnaces comprises a conventional continuous mesh-belt wound at one end around an idle reversing roller and engaged at its other end in a labyrinth device subjected to a reciprocating motion in the general direction of the conveyor, the belt being also intermittently clamped, close to the reversing roller, by a gripping device which produces intermittent movements of the belt toward the reversing roller in alternation with the movements of the labyrinth device, in order to cause an intermittent advance of the belt.
Claims8
An endless belt conveyor disposed in an elongated path having at one end an idle reversing roller about which the conveyor is trained and at the other end a labyrinth device through which the endless conveyor is trained, means mounting the labyrinth device for movement toward and away from the reversing roller, the labyrinth device when moving away from the reversing roller exerting greater friction on the endless belt conveyor than when moving toward the reversing roller, the endless belt conveyor having substantial slack when said labyrinth device is nearest said reversing roller, and means for gripping and advancing said slack toward said reversing roller, said labyrinth device and said means for gripping and advancing cooperatively serving to intermittently advance said endless belt conveyor.
