Shearing systems

Linear shears

The kinematically decoupled shear blades can be moved by two direct drive linear motors and, if necessary, independently of each other.  A particular advantage is the high dynamics of the traversing axes (Y1, Y2).  This design principle leads to more precise cuts, a more compact design of the system and shorter set-up times with minimal maintenance.

Retro-fit shears

Products of impeccable quality require exact and reproducible movement of the shear blades in production process.  Accordingly, we modified an existing pneumatic shear system into Retro-Fit shears that make use of servo technology.  The system can be adapted without modification to the existing platform.


  • Technical data:
  • - Basic dimensions (L x W x H): 1,000 x 560 x 530 mm
  • - Weight: approx. 100 kg
  • - Max. production speed: 50 1/min
  • - Max. motor torque: 4.7 Nm

Advantages of the linear shear

Advantages of the retro-fit shears

  • Vertical position of the shear arms manually adjustable by up to 20 mm (Z)
  • Maximum opening 180 mm (Y)
  • Quick blade change with quick change system
  • Precise adjustment of blades using an external blade adjuster
  • Long service life due to water cooling of the entire system
  • Easy Integration into all production plants for hot forming
  • Higher dynamic and reproducible movements
  • No mechanical play
  • No wear
  • Set-up possible during operation
  • Accelerations and speeds of the closing and opening movements of the shears are freely programmable
  • Precise cutting of the glass mass without knocking or vibration
  • Variable blade crossover adjustable by software during operation
  • No mechanical play and quick blade change due to pneumatic clamping unit
  • Entire system swings out to allow risk-free changing of the unit
  • Additional settings for double-gob application (precise alignment of the cutting and feeder orifice positions; the gob terminator is not required)
