Abstract

A method and a device for screw capping vessels, in particular bottles, by measuring the power consumption of a linear drive system for lifting and lowering the closing head in a pick phase for picking up the respective closing cap and/or in a screw phase for screwing on the closing cap being, and by comparing that measured power consumption with at least one characteristic value of the power consumption to detect an imminent or occurred incorrect closure. In this manner, vessels can be closed at a low error rate and possibly incorrectly closed vessels can be discharged from a continuous product stream at a low error rate.
