ABSTRACT:
In a pressure head for a screen printing press, the pressure doctor consists of a doctor bracket and an elongate support rail made of a hard resilient material inserted removably therein, and a profile bar made of a soft resilient material. This profile bar is fastened to the edge of the support rail underneath in service. A bracing profile made of a hard resilient material attached to the doctor bracket is provided to brace the support rail. Where the pressure head carries, for the purpose of better ink distribution, a preliminary doctor which is lowered alternately with the pressure doctor, this preliminary doctor is of curved and pivotable construction.
