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.

Sliver channel with reduced friction

An apparatus for determining a point of regulation in a drafting unit includes a sensor for generating signals as a function of change in a quality-representing magnitude of the fiber material running through the drafting unit; a control device receiving the signals for varying a draft of the fiber material by the drafting unit; and an arrangement for continuously determining, during operation, optimal points of regulation based on the signals.

Method and apparatus for determining the point of regulation for a drafting unit in a fiber processing machine

A fiber processing machine includes a sliver drafting unit which has first and second adjoining roll assemblies each defining a nip through which a sliver runs in a sliver advancing direction. The second roll assembly is spaced downstream of the first roll assembly. The nips of the first and second roll assemblies together define a principal drafting field and the drafting direction thereof. At least two pressure bars are disposed in the principal drafting field for contacting and deflecting the sliver from the drafting direction as the sliver advances from the first roll assembly to the second roll assembly.
