US 7,810,448 B2 · Apparatus and method for the treating of workpieces

Abstract

The invention relates to an apparatus and a method for the coating of hollow bodies, in particular for the internal coating of plastic drinks bottles by means of a PICVD. It is an object of the invention to ensure a flexible process sequence, a high throughput, an improved supply of fluid and a high-quality coating. The invention in particular proposes a rotary apparatus which comprises a treatment device with double reactors for receiving in each case at least one workpiece, a fluid supply apparatus and at least one fluid control device, which can be used to control the supply of fluid to the treatment device. It is preferable for the vacuum pumps to be arranged on the rotor such that they rotate therewith.
