Sliver drawing roller gap adjustment - uses a housing with insert plates to displace it from roller axis

摘要

The mounting system to give a variable gap between grooved rollers, for use in drawing sliver for carding or stretching to impose a crimp in the sliver partic. for cotton fibres, has a bearing housing where at least two surfaces work with a counter-surface giving various distances for the rotary axis of the upper roller. The design gives a rapid and accurate adjustment of the gap between the rollers, without requiring feelers and time-consuming adjustment procedures.
