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, a sliver outlet, and a plurality of air inlets in the sliver channel wall for introducing air into the sliver channel. 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 sliver is subject to a tensioning draft, and the air introduced into the sliver channel is for acting on the sliver to reduce a frictional force between the sliver and the inside wall surface of the sliver channel.
