Abstract

A coiler plate is provided for sliver coil depositing. The coiler plate has a rotational axis, a spatially curved sliver channel having a wall, an inside wall surface, a sliver inlet, and a sliver outlet. The sliver inlet is arranged substantially coaxial with the rotational axis, and the sliver outlet is arranged at a radial distance and an axial distance from the sliver inlet. The device has a field producer that produces at least one of a magnetic field and an electric field. The field is for acting on the sliver such that the sliver is positioned away from at least a portion of the sliver channel inside wall surface.
