DEVICE FOR DRAFTING A ROVING IN SPINNING MACHINES

摘要

The present invention concerns a method for processing a fiber sliver in a drafting arrangement, and a drafting arrangement for implementing the method. The objective for a drafting arrangement, which can be adapted to a wide range of staple lengths, to draft a fiber sliver at high speeds, has led to the following features of the invention: (a) The fiber sliver is deflected simultaneously in the drafting process systematically in such a manner that, the fiber sliver can be inserted into the subsequently arranged funnel and the subsequently arranged pair of calender rolls without further deflection.
