Reed Marks and Starting Marks Read Back to the Loom
Greige reed marks and starting marks map directly to reed wire spacing and loom stoppage dynamics, requiring electronic let-off adjustment to eliminate defects.
Beat Up
Mechanical Impact
The beat up defines a deliberate physical stress applied to warp yarns during the loom shedding sequence to ensure proper spacing and tension before the shuttle passage. This adjustment requires synchronized timing between the reed and the heddles to prevent yarn breakage. High speed looms depend on this motion to maintain consistent cloth density throughout the roll.
Technicians track the specific stroke distance to verify that friction remains within acceptable parameters for delicate flax fibres. Correct settings guarantee that each pick occupies the designated position without damaging the natural structure of the cellulose.
Production Velocity
Precise calibration of this phase governs the output rate of the finished textile. Faster stroke cycles increase total output but also raise the risk of snapping individual fibres if the reed impacts with too much force. Mills manage the trade off by adjusting the power output of the drive motor.
Consistent force prevents uneven gaps in the final product. Every loom maintains a unique rhythm determined by the density of the pattern and the quality of the raw material supplied from the spinning floor. Excessive speed often leads to inconsistent tension across the width of the fabric.
Engineers monitor these variables to maintain high standards of quality control during the entire spinning and weaving run.
Tolerance Standard
Acceptance criteria for exported linen rely on the absence of abrasions or thinning caused by incorrect movement of the reed against the warp. Buyers specify the maximum force allowed to avoid weakening the integrity of the finished cloth. Mill supervisors compare the actual stroke pattern against the established baseline recorded in the initial process specification document.
Any deviation during the weaving stage results in an immediate halt to correct the mechanical timing of the loom. Independent auditors test the fabric for structural defects that originate from this exact point in the assembly. A stable and measured stroke produces the only acceptable result for high grade linen inventory destined for commercial garment manufacturers.
