A roving machine and method for producing a roving from a fiber sliver has at least one spinning station with a vortex chamber, an infeed opening for the fiber sliver, and a roving forming element in the form of a spindle that has an inlet port and extends at least partially into the vortex chamber. In a particular form, a processing module can include a local processor configurable to initiate access to resources of a host processing system. The memory can be arranged in numerous erasable blocks andor sub-blocks. The inner andor outer disk carrier have a toothed component, which is fixed to and at least partially axially and radially encompasses a basic component. Each optical filter is configured to pass a sub-group of the WDM signals while blocking other WDM signals such that each of the second group of CPs receives its own allocation of WDM signals but does not receive WDM signals allocated to other CPs of the second group of CPs.
