    1. Option 1: Manual type         Option 2:Hydraulic type
      2.Shear and butt-welding machine:
      It is used to shearing the head and the end of the steel strip of two steel coil, cutting off the irregular part then welding two steel strip, so machine can working continuously.
      The shearing mechanism adopts the three blade shear when two upper blades are fixed to the upper cutterblock which is connected to the framework by means of the shoulder and bolts. The lower blade is mounted to the movable lower cutterblock with this blade face slanting.  The lower cutterblock is driven by the air cylinder to effect up and down movement.
      (1) Strip width: ≤240mm; 
      (2) Strip thickness: 0.8~3.0 mm
      (3) Welding speed: 75~350mm/min;
      (4) Welding current: 16~250A;


      Shear and welding machine
      3. Accumulator(Optional) 
      This unit is to store enough strips so the machine can producing continuously without stop, have squirrel-cage type and spiral type can be select.
      Option 1: Squirrel-cage type(Double layer type)
             The structure is squirrel-cage with weld assembly type,
      equipped with fast feeding device, so strips can enter inside. Width of squirrel-cage accumulator can be adjusted according to different strip width  Pneumatic component: Airtac
      Drive motor:11KW   Brand:Siemns
       Squirrel-cage type   
      Option 2: Spiral type Pneumatic component: Airtac
      The structure adopt the storing method which is strips entering from outside and output from inside, spiral enclosure
        is consist of many rolls and form a similar spiral surface, cambered surface center spatial position formed from every roll is differ from one another, ensure each roll outside generatrix touch with steel strip completely, steel strip have no plastic deformation.
