The roller comprises a covering layer made of a fibre composite material and a cylindrical roller main body having an outer first lateral surface, a first end section and a second end section. The covering layer completely surrounds the first lateral surface in the circumferential direction. A first edge region of the covering layer extends beyond the first end section, is folded over inwards and is fixed in relation to the roller main body. In a crosslapper, the roller can be provided as a deflection roller of a conveyor belt. In a carding machine, the roller can be provided as an engagement roller for engagement with fibre material.

The disclosure relates to a device and method for extracting synthetic fiber material from mixed textile waste fiber material containing synthetic fiber material and natural fiber material. An extraction module includes an electrostatic charging unit that is configured to be mountable at a textile recycling machine for electric charging a fiber fleece of mixed textile fiber material and/or for moving charged synthetic fiber material closer to a surface of the fleece, and a separation stage comprising separation means for removing a layer, in particular surface layer, of the fleece containing an increased or decreased concentration of the synthetic fiber material. Also a method for retrofitting a textile recycling machine with such an extraction module is disclosed.
