A squeegee for a screen-printing machine, in particular a rotary screen-printing machine, comprises a supporting part, which can in principle be attached permanently to the frame of a screen-printing machine, as well as a removable part, which is detachably connected to the supporting part. The supporting part is designed as a rigid bar which extends in the longitudinal direction of the squeegee. The removable part is displaceable in the longitudinal direction with respect to the supporting part. The removable part forms the active squeegee part. The supporting part may be of rigid design, while the removable part may be of lightweight design. The removable part comprises in particular those components which regularly have to be removed from the screen-printing machine.

Squeegee with a fixed supporting part

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 as well as a paste suction line and a paste pressure line, while the cleaning device at least comprises a cleaning agent container, for liquid cleaning agent, by means of which the paste suction line and the paste pressure line 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.
