Rotary screen printing machine for web material - has moistening unit to prevent printing ink from drying in pores of screen (NL140377)
Реферат: The rotary screen printing machine for web material has a porous cylindrical screen containing a wiper and a supply unit for printing ink or paste. The dry mass content of the printing paste in the pores as well as within the screen is held to a value which deviates by no more than approx. 20% from the dry mass content of the supplied printing paste. In this way pore blockage by drying paste is avoided. The printing paste is kept moist by damping liquid fed via a supply line through a pump (10) to an atomiser head (12) positioned near to the screen surface (2). The head incorporates several nozzles arranged in a row parallel to the axis of the cylindrical screen.
