Chalcographic printer is the name given to a specific type of press which is used to transfer the printing of a metal-based engraved plate onto paper. The printing system consists of two rollers for pressing and carrying a metal plate onto which an engraved inked plate is placed. When the driving mechanism is operated, the pressure exerted by the rollers, also called contact pressure, allows th...

in this study, the effect of furrow firming rollers were investigated to improve furrow irrigation parameters such as: advance time, runoff, deep percolation and irrigation efficiency (application efficiency) in the roller treatments, nonroller treatments (traditional) and treatment of including compacted with tractor wheel in the miandab agriculctural station in west azerbaijan during 2001-200...

Abstract. Centrifugal pendulum absorbers are passive dampers mainly employed nowadays to attenuate torsional vibrations in modern drivetrains reduce fuel consumption and CO2 emissions. The absorber is linked the drivetrain by means of a higher kinematic joint composed slots rollers, termed caged-roller joint. This work aims investigate contact between rollers through multibody dynamics simulati...

The expectations placed on packaging continue to rise. It must provide enhanced product protection, greater convenience and catch the eyes of consumers while offering optimum efficiency and sustainability. Companies producing flexible packaging are responding to these challenges by developing complex, multi-layer composite films and using special raw materials. Whenever this approach reaches it...
