Abstract (en)
[origin: EP2281683A1] The method involves pneumatically pre-pressing of different cosmetic loose powders to semi circle powder blanks (14, 15) by negative pressure created by a pressure line or mechanically pre-pressing of the loose powders to the powder blanks by a die moveable in a compression chamber. The pre-pressed powder blanks are pressed together in a pan (16) to form a pressed powder element. Pressure is exerted upon the powder blanks during pressing the powder blanks together, where the pressure is selected as high pressure that activates a binder phase in the powder blanks. An independent claim is also included for a device for producing a pressed powder element.
