The method of separating the web on this condenser gives avery even roving, with little tendency to variation. It is alsopossible to make an unusually light roving, since other methodsof condensing require that the strip of web from the doffer be strongenough to sustain its own weight. For the same reason it is possibleto run very Short Staple because light roving can be spun withvery little draft into fairly fine numbers of yarn. In quantity ofProduction, too, this type of condenser has the advantage overthe old types, and marks a distinct advance in the methods ofhandling low grade cotton waste. Page 39.
