Machines for impelling textiles while submerged in a liquid.
(1) Note. See definition of impulsing in main class definition of this class.
(2) Note. Impulsers using impellers are distinguished from machines using drags or dollies by function and structure. The function of an impeller is to impart a force to the textile so as to cause it to move a distance independently of the impeller; the function of a drag or dolly is to move the textile with the drag in its movement or movements.In structure, the impeller, used is an impulser, is generally a broad flat surface which may or may not be perforate, and which has an intermittent movement. The drag or dolly generally consists of a pin or plurality of pins or an open grille work to cause textiles to move with the drag or dolly, said drag or dolly having either a continuous rotary movement or a reciprocating movement. Impulsers and drags are distinguished from squeezing machines in that there is no surface cooperating with the impeller or drag between which surface and the impeller or drag the textiles may be compresses.
