Abstract (en)
[origin: WO2019175142A1] The invention relates to a device for feeding liquid paint and/or liquid additive to a melt flow of molten polymer. A feed lance is used for this purpose, having a paint channel for supplying the liquid paint and/or the liquid additive, wherein an outlet of the paint channel is designed as a paint nozzle. In such devices, changing over between different paints or a paint-free production for example is problematic. Waste is produced in said changeover processes. According to the invention, a paint change is carried out in a particularly fast and frictionless manner in that the paint nozzle can be closed from the outside such that the inflow of the liquid paint and/or the liquid additive into the melt flow is interrupted.
