Abstract
An apparatus for smoothing a workpiece has a housing that is displaced relative to the workpiece in a direction and that carries a pair of augers provided with respective screwthreads having outer edges in contact with the workpiece. These augers are rotated on the housing about respective generally parallel axes transverse to the direction so as to scrape the workpiece with the screwthreads. Furthermore the augers are of such a hand and the are rotated in such a direction that the augers exert on the workpiece opposite axially directed forces.
Claims20
An apparatus for smoothing of continuous gypsum-fiber panels and similar panels, the apparatus comprising:
- a frame;
- a conveyor on the frame;
- and
- at least one rotatable and driven auger extending transversely above the conveyor for removing fine particles of the surface to be smoothed.
A portable hand tool for smoothing strips, the hand tool comprising:
- a housing;
- a row of support rollers spaced from a sole plate of the housing, and
- at least one rotatably driven auger mounted in the housing parallel to the support rollers and provided with a drive for removing fine particles of a surface of the strip to be smoothed.
An installation for continuously making gypsum-fiber panels, the installation comprising
- devices for forming rough panels that have a mixture of bindable gypsum, fibers, and stoichiometrically excess amount of water,
- a binding station for the rough panels,
- a dryer after the binding station, and
- an apparatus for smoothing the passing panels between the binding station and the dryer, the apparatus comprising:
- a frame;
- a conveyor;
- and
- at least one rotatable and driven auger extending transversely above the conveyor for removing fine particles of the surface to be smoothed.
An apparatus for smoothing a workpiece, the apparatus comprising:
- a housing;
- means for relatively displacing the housing and the workpiece in a direction;
- a pair of augers provided with respective screwthreads having outer edges in contact with the workpiece, the augers being rotatable on the housing about respective generally parallel axes transverse to the direction;
- and
- means for rotating the augers about the respective axes and thereby scraping the workpiece with the screwthreads, the augers being of such a hand and the means rotating the augers in such a direction that the augers exert on the workpiece opposite axially directed forces.
