PROCESS FOR CONTROLLED RELEASE OF LIQUIDS OR DOSED SUSPENSIONS OF LUBRICANT IN COATING WITH LUBRICANTS FROM MECHANICALLY REQUESTED PRESSING TOOLS AND DEVICE FOR CONCRETIZING THE PROCESS

摘要

1. Process for the controlled release of metered lubricating liquids or suspensions in applying a coating of lubricant to mechanically stressed zones of pressing tools in tablet-making machines, in which the lubricant solution or suspension is metered to one or more liquid valves (F) from an unpressurised storage container (V) by means of a pump (P) operating without pulsations, in such a way that the metering is in synchronism with the cadence of the table-making machine, characterised in that an under- or over- pressure prevailing at the pump outlet and measured against a rated pressure brings about a change in the times of opening of the liquid valves (F), or optionally changes in pressure may be equalised upstream of the pressure gas valves (L) by changes in the times of opening these pressure gas valves.
