Abstract:
1. A method for continuously producing a multiplicity of articles comprising at least two different types of articles from a pasty mass, using a device for continuously producing a multiplicity of articles, the device comprising: a screw extruder comprising axial regions comprising: a metering unit connected by means of at least one switching unit to at least one source of a respective additive, wherein the or each respective switching unit is configured to be switched into a respective switching state; and a molding unit, provided after the processing unit, with molding elements downstream of the mixing unit, for molding the mass provided with at least one of said additives into individual articles; the method having the following steps: feeding the mass by the feeding unit into the processing unit; transporting and processing the mass through the processing unit; metering at least one of said additives by the metering unit into the mass transported through the processing unit; mixing said at least one metered-in additive into the mass by the mixing unit; molding the mass provided with said at least one additive into individual articles by the molding unit; wherein the metering in of said at least one additive takes place in a sequence of metering states comprising at least two different metering states, wherein the metering unit in a respective metering state meters at least one respective additive of said at least one additive into the mass at a respective metering rate; wherein a duration of the metering state or a duration of a metering cycle is less than approximately 40 seconds; wherein a switching over duration between different metering states is approximately 0.1 s to 1 s.
