Jacquard Repeat Length Priced as Card Time and Loom Hours
Pricing Jacquard repeat length requires balancing flat card preparation fees against loom hour rate increases caused by harness mass speed penalties.
Point Tie Mirroring
Design Arrangement
Symmetrical harness threading system used in Jacquard weaving to duplicate a design pattern across the width of the fabric is a standard technique for producing linen table linens and decorative borders. This point tie mirroring reduces the number of design cards or digital memory required by reflecting the pattern from a central pivot point. It is detailed in the loom harness draft plan and recorded on the fabric design specification.
Weaving Geometry
Harness cords are threaded so that the left side of the fabric is woven in reverse image to the right side, sharing a common center thread. This arrangement allows a mill to weave wide, intricate patterns using a relatively small Jacquard machine. The point tie mirroring configuration must be carefully balanced during warping, as any misalignment in thread count will cause the pattern to appear skewed or asymmetric.
Symmetrical designs in heavy linen require precise tension control on the border threads to prevent puckering after wet finishing.
Production Utility
Writers of fabric designs use this threading method to create ornate, bordered tablecloths and runners from a single pattern file. Correct execution is verified during the first loom trial by comparing the woven pattern to the paper layout. This check ensures that the final product meets the buyer’s aesthetic expectations.
