PRESSING DEVICE FOR PRODUCING A BLANK, ALSO A METHOD FOR THIS PURPOSE AND A BLANK

摘要

The present invention relates to a pressing device comprising a device for filling a mould of the pressing device with at least two different materials, a cavity (112) which is to be filled with the at least two materials (124, 126, 128), and a filling device (120) for discharging the at least two materials (124, 126, 128) in order to be able to introduce said materials (124, 126, 128) into different areas of the cavity (112). Said filling device (120) comprises at least two separate chambers (130, 132, 134) or at least two chamber areas of a common chamber for simultaneously feeding the at least two materials (124, 126, 128), directly adjacent to each other or spatially separate from each other, for introducing the same into the cavity (112) as layers which are at least partially different from each other and with a relative rotational movement between the filling device (120) and the cavity (112).
