The impact of border ruler on processing parameters of straight seam sewing operation

The investigations are presented of the impact of a sewing machine mechanical attachment, border ruler, on processing parameters in sewing operations. Processing parameters are measured and values stored employing the MMPP system of measuring them. Operation structure is altered using the border ruler and movements of auxiliary-hand sub-operations are made more rational, which considerably improves processing parameter values. Using the border ruler, basic time for the operation is reduced by 28.9%, sewing machine utilisation degree is reduced for short seams up to 15.6%, and increased for long seams (700 and 1000 mm) up to 30.1%. Specific sewing time for 1 m of seam is reduced by 34.0%, while average stitching speed for the machine-hand sub-operations is increased by as much as 75.8 %.
