Abstract

An apparatus for cutting an advancing yarn which comprises a cutting blade which is oriented with respect to the advancing yarn, such that when the advancing yarn and blade are moved into engagement, the yarn is deflected from its path of travel to increase its tension, and the yarn moves along the cutting edge of the blade with no substantial component of movement transverse to the cutting edge. The yarn is thus cleanly cut at a single point along its length, in the same manner as a stationary yarn is cut by hand with a knife.
