Abstract:
In a web layering device composed of a series of conveyors disposed in sequence for conveying a web of textile fibers from a card and depositing the web in layered form on a transporting unit, at least some of the conveyors being mounted on carriages to undergo back and forth movement, the attainable web conveying speed is increased by disposing an air guidance member in the form of a plate at at least one region of transfer between two conveyors to create an air stream which travels substantially tangentially to the web travel path.
Abstract:
Apparatus for producing a web whose width exceeds the working width of a machine having a number of take-off units and a table for conveying the web, for the production of webs from fibrous material, more particularly cards, carding machines, or pneumatic non-woven formers, the device having deflectors (12) which are associated one each with the take-off units (10) and which, as considered in the operative direction of the machine, are spaced apart from one another by a distance corresponding to the width of the taken-off web, the deflectors (12) extending at an angle to the operative direction of the machine, such angle corresponding to half the angle between the operative direction of the take-off table (10) and that of the table (14) for conveying the textile, and a corresponding method.
Abstract:
An apparatus for producing fiber material or the like with a prescribable feed weight comprises a conveyor for delivering the fiber flock to a filling stack, which includes a vibrating wall extending in a vertical direction and a displaceable wall, a stationary delivery roller being arranged in a discharge region of the filling stack and a displaceable delivery roller being arranged opposite the stationary roller in the discharge region for controlling the thickness of the layer being deposited on a conveyor. The apparatus also includes a pressure sensor which is provided between the two delivery rollers, which pressure sensor provides signals for controlling the displacement of the displaceable delivery roller, the vibratory frequency for the vibrating wall of the stack and the displacement of the movable wall.
