A CLEANING DEVICE FOR USE IN CLEANING A PASTE SUPPLY SYSTEM OF A ROTARY SCREEN-PRINTING MACHINE

摘要

The invention relates to a cleaning device for use in cleaning a paste supply system of a rotary screen- printing machine, which paste supply system at least comprises a pump (7) as well as a paste suction line (5, 5a, 5b) and a paste pressure line (6), while the cleaning device at least comprises a cleaning agent container (8), for liquid cleaning agent, by means of which the paste suction line (5, 5a, 5b) and the paste pressure line (6) can be placed in liquid communication for the purpose of interaction between the paste supply system and the cleaning device, the cleaning device being characterized in that flow-altering means are present. Preferably, the flow- altering means which impart to the cleaning agent, as it flows through the cleaning device and the paste supply system interacting therewith, a direction of flow at least over part of the paste suction line and/or the paste pressure line which has both an axial and a radially outwardly directed velocity component. The advantage of a cleaning system of this kind is that a pump device having a lower pump capacity than was usual hitherto can be used, and in addition lines having a larger cross-section can be effectively cleaned.
