1919 illustrated and descriptive catalog of Whitin cotton waste machinery . he lattice used with the Scotch feedmakes it feasible to use very short staple without the sliver breakingdown. From the finisher card the web is carried to a four-bankTape Condenser which separates and condenses it into from80 to 96 good ends of roving, according to the class of work to bedone. This type of condenser can make a much finer roving thanthe older types, with little variation in the size of the ends, andthe spools of roving can be spun to comparatively fine numbersof waste yarn with very slight draft. Both Breaker and Finisher Cards have a fancy roll, andall rolls have shell ends. The workers are chain-driven and thetops of the cards have substantial steel covers. The doffer combmotion which is run in oil, contained in an oil-tight comb-box, canbe driven at high speed without heat, noise or undue vibration. The Production of this set is from 175 to 300 pounds per dayof 10 hours. For detailed specifications, see descriptions of in-dividual cards on pages 30 and 33. Page 37. FOUR-BANK TAPE CONDENSER The Four-Bank Tape Condenser is a modern and mostsuccessful machine for condensing cotton waste roving, especiallyif the roving is to be spun into comparatively fine yarn. Withthis condenser the web from the card doffer passes between twogrooved rolls, which separate the web into strips of exactly equalwidth, very much in the same manner that a piece of sheet steelis sheared by cutting rolls. The grip is not positive enough, how-ever, to cut any individual fibres. Running in the grooves of bothtop and bottom dividing rolls are leather tapes to which the narrowstrips of cotton web adhere as soon as they are separated. Thesetapes carry the web to the condenser rolls, which detach the webfrom the tape and rub it into roving, making from 80 to 96 goodends. The method of separating the web on this condenser gives avery even roving, with little tendency to variation. It is alsopossible to ma
