Method for continuous metering stapel fibres to screw machines

摘要

Continuous dosing of finite-length textile fiber materials to screw machines comprises producing a clutch (1) with a defined surface mass and spreading width from the fibers, placing on a conveyor belt and feeding continuously to an extruder. The clutch is compacted by an assembly comprising at least two conveyor belts between which the clutch passes to a defined thickness that is smaller than the thickness of the feeder slot on the extruder. An independent claim is also included for a device for continuous dosing of finite-length textile fiber materials to screw machines comprising at least a first horizontally arranged conveyor belt, on top of which the clutch produced from fibers is placed with the defined surface mass and spreading width, and the extruder with the feeder slot, where the fabric is fed continuously. The device further comprises at least a second conveyor belt (3) that is arranged above the first conveyor belt (2) with a gap distance and at an acute angle, which the gap distance between two conveyor belts narrows down in the conveying direction to the feeder slot of the extruder and the clutch is compacted continuously between two conveyor belts before reaching the feeder slot of the extruder by the conveyor belts.
