Reed Beat-Up Mechanism Design
topic
Reed beat-up mechanisms use conjugate cams or crank drives to move the sley carrying the profiled reed in a dwell-advance-dwell motion cycle that positions the reed at rest during weft insertion, advances rapidly to beat the inserted pick to the cloth fell, and returns to the insertion position, with sley mass, beat-up acceleration, and dwell period angle determining the beat-up impulse that consolidates the weft into the fabric structure.
Role
Controls the pick consolidation force that determines fabric pick density and cover factor, with beat-up force magnitude and timing governing how completely each weft pick is driven to the fell line to achieve the target picks per centimetre in the woven fabric, and sley kinematics optimization determining the balance between dwell time available for weft insertion and beat-up impulse time available for pick consolidation.
