ABSTRACT:
Extra coagulant is added to the cuff portion of the former by a spray nozzle located between the coagulant and latex dipping tanks. A former is placed into a coagulant. After removal from the coagulant, additional coagulant to the cuff portion of the former by any conventional means, such as a spray nozzle. The higher concentration of coagulant at the cuff portion results in a thicker latex thickness at the cuff portion and counteracts the reduced dwell time of the cuff in the latex dipping tank as compared to the fingertip portion of the former. The thickness of the cuff portion can be controlled by altering the concentration of the coagulant applied by the spray nozzle.
