Higher production efficiency
According to calculations within different weaving mills, an average increase in efficiency of 3% has been achieved when using the Loepfe weft thread brake WeftMaster SFB-L.
3% increase of efficiency results in an additional profit of around USD 6250.-- to USD 9370.-- per year. Consequently the weft thread brake WeftMaster SFB-L is amortized within a very short time, i.e. in the present case within less than 4 months.
The following calculation is based on the details given from the weaving mills and for unknown parameters has been indicated an estimated value.
|Number of weaving machines||100 P7100 ES, 10 TW-11 ES|
|Speed/number of picks per minute||420|
|Production of 100'000 picks in||4 hours / machine|
|Production of 600'000 picks in||24 hours / machine|
|Number of weft breaks||4 - 6 per 100'000 picks|
|Number of weft breaks||30 per machine / 24 hours|
|Total number of weft breaks||3000 per 100 machines / 24|
|Total time consumption / repair of weft breaks||3000 x 4 min. = 12000 min. = 200 hours|
By using the electronic weft thread brake WeftMaster SFB-L, the number of weft breaks can be reduced with at least 50%, which means:
|Reduction of weft breaks||instead of 6, only 2 - 3 per 100'000 picks|
|Total reduction of weft breaks||Ø 6000 min. / 24 h / 100 machines|
|Reduction of weft break repair time||Ø 100 hours on average|
|Resulting in an increase in efficiency of||Ø 3% on average|
Using the weft thread brake WeftMaster SFB-L pays off quickly and clearly ameliorates the quality of the fabric. Each weft break is a potential fault source (among others starting defects, formation of stripes etc.).
