由西安重型机械研究所研制的纵剪用多条送头与张紧装置于一九八七年十二月二十五日至二十六日在西安重型机械研究所通过技术鉴定。鉴定会认为:纵剪用多条送头与张紧装置的研制系国内首创,原理可行,结构简单,工作平稳,张紧可调,它具有自动夹紧、分离、送料以及无接触恒张力卷取等功能,填补了国内空白,达到当前国外同类设备水平。纵剪用多条送头与张紧装置的研究成功,解决了有色金属,特别是铝板带纵剪机组长期未能解决的技术问题,其中多条送 The multiple slitting heads and tensioning devices developed by Xi’an Heavy Machinery Research Institute passed the technical appraisal at Xi’an Heavy Machinery Research Institute from December 25 to August 26, 1987. Identification will think: Slitting with a number of head and tension device developed by the domestic initiative, the principle feasible, simple structure, stable work, adjustable tension, it has automatic clamping, separation, feeding and non-contact constant tension roll Take the other functions, to fill the gaps in the country to reach the current level of similar foreign equipment. Slitting with a number of head and the success of the tensioning device research to solve the non-ferrous metals, especially aluminum strip slitting unit has long been unable to solve the technical problems, including multiple send
