摘要

The machine (1) has a pickup device (4) with freely projecting prickers (42), and a back pressure device (2) cooperating with the pickup device, where the back pressure device has support regions (22) and gaps lying between the support regions. The prickers of the pickup device penetrate through the gaps by skewering cardboard portions of a paper mixture, where the pickup device is arranged below the back pressure device. The pickup device and/or the back pressure device are formed as rotatable rollers. An independent claim is also included for a plant comprising a feeding device for supplying paper mixture to a machine for selecting cardboard portions from the paper mixture.
