Beat-Up Force Measurement and Control
topic
Beat-up force measurement uses strain gauge load cells mounted on the reed support to measure the force transmitted to the cloth fell during each beat-up, with typical forces of 500 to 5000 Newtons per metre of fabric width depending on pick density and yarn count, and with beat-up force being indirectly controlled through warp tension level and fabric take-up rate that together determine the fell resistance that the reed force must overcome to advance the pick to the target spacing.
Role
Quantifies the compaction force applied to each weft pick that determines whether the pick reaches its target position in the fabric or is insufficiently compacted, with beat-up force measurement being a valuable diagnostic tool for understanding why specific fabric constructions do not achieve their target pick density and for comparing the beat-up force requirements of different fabric specifications to assess whether loom structural capability is adequate.
