The order from the Chinese Academy of Sciences (CAS) requires a high precision of sewing. The special material to be sewn is a 4 mm thick PVC sheet with a gauge of 1300 *900 mm. The stitch length is required to reach 1 cm. The sewing must be done at 5 mm of the edge of the material to ensure that the sewing joint is strong and reliable, and the material is very expensive, the material will be write-off if false stitch. This machine needs to meet the high precision and wide range requirements of the Chinese Academy of Sciences, so we spent six months to solve the difficult problems one by one according to the special technologi-cal requirements of the Chinese Academy of Sciences, the bottleneck technology of the project in the field of sewing subdivision is realized. The sewn products are used in solar cell mounting interfaces for near space solar vehicles at altitudes of 20,000 to 40,000 meters.

          2022,Leman Advanced customization rotating head template machine supplied to CAS again!

          Once again, according to the needs of the Scientific Research Mission of the Chinese Academy of Sciences, sewing the interface of solar cell modules for airships. It is very difficult to realize the machining of such interface. After research, on the basis of the 3-axis automatic template machine provided in 2016, we have developed the 7-axis Advanced customization rotating head template machine. The head can lift and rotate ,sewing without dead angle for heavier material, more larger sewing size (up to 1500X1100MM),more higher precision can stitch 3mm near the pole edge,and need easier operation & higher automation to meet the sewing requirements of solar cell module interface for airship.
