Calculating Electronic Card Setup Fees and Loom Hour Output Surcharges
Electronic card fees cover digital hook mapping while loom hour output surcharges adjust metre costs for reduced insertion speed and lower shed efficiency.
Bonas File Format
Binary Encoding
Machine control protocols translate textile designs into low level binary commands that govern automated jacquard shedding heads. The bonas file format defines the hook position arrays required by electronic shedding mechanisms on industrial rapier looms. Production software generates these numeric arrays from digital artwork, assigning an on or off state to every harness hook for each machine pick.
Chinese flax processing facilities load these compiled files directly into loom controllers to form complex damask patterns in wet spun linen cloth. Operational boundaries restrict this data stream to the physical hook capacity of the attached jacquard head, rejecting instructions that exceed the addressed harness volume.
Pattern Translation
Industrial computer aided design systems convert finished pattern drafts into proprietary machine instructions through dedicated compilation routines. The bonas file format arranges warp lift sequences into dense columnar records, matching pixel data to physical hook coordinates across the gantry. Loom microprocessors parse these binary blocks sequentially during beat up cycles, actuating electromagnetic selectors that lift designated linen warp ends.
Missing header parameters or corrupted byte allocations cause immediate loom halt states, which prevents mispicks in high density linen table fabrics. The mill inspection team cross references the compiled file header with the loom setup sheet before launching continuous production runs.
Loom Operation
Electronic shedding controllers verify memory allocation and file checksums before initiating rapier cycles on the production floor. The bonas file format remains tied to specific controller hardware generations, requiring post processing conversions when transferring production batches between older Bonas heads and modern electronic interfaces. Export quality linen fabrics depend on precise lift execution to avoid irregular floats or broken linen filaments across long run batches.
Cloth inspectors record any pattern discrepancy against the digital design approval document. Production technicians archive the final validated file on the mill central server alongside the corresponding fabric technical specification sheet.
