Resolving Edge Tension Drift and Temple Mark Variations on Wide Air-Jet Linen Weaving Warps
Wide air-jet linen weaving requires synchronized relay nozzle pressures and precise temple pin geometry to stop edge tension drift and edge damage.
Temple Rolls
Width Retention
Toothed cylindrical rollers mounted at the cloth fell edges maintain full woven fabric width against warp contraction forces during beat-up. In air-jet and rapier weaving of linen, temple rolls prevent excessive fabric drawdown and reduce edge thread breakage caused by high warp tension. Stiff flax yarns exert strong lateral contraction forces on the cloth fell, making mechanical width retention critical for preserving selvedge integrity.
Selecting appropriate ring configurations and pin lengths ensures proper fabric holding power without punching visible holes in delicate weaves.
Mechanical Grip
Spindles fitted with angled brass or synthetic rings grip the fabric edges as cloth advances onto the take-up roll. Spiral pin patterns on temple rolls push the selvedge outward to balance inner warp tension. Loom tuners adjust temple height, angle, and clearance to prevent pin marks from marring the finished cloth surface.
Regular inspection identifies worn pins that slip or snag warp threads.
Defect Prevention
Incorrect temple selection causes severe edge defects including broken selvedge threads, pin holes, and temple marks. Maintaining proper temple roll settings ensures clean fabric edges during continuous weaving runs. Inspection teams flag temple damage during grey cloth grading before rolls pass to the finishing department.
Proper temple maintenance extends reed life and ensures uniform fabric width.
