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.
Claims
exact text as granted — not AI-modified1 . A method for making articles, comprising
dipping a former into coagulant, the forming having a first end and a second end, said first end placed into said coagulant before said second end, removing said former from said coagulant, applying coagulant to said former second and dipping said former into rubber material, said first end placed into a said rubber material before said second end.
2 . The method of claim 1 , further comprising
applying said coagulant by spraying.
3 . The method of claim 1 , wherein said rubber material is nitrile rubber or latex rubber.

8 . A method of forming articles, comprising
applying a first coat of coagulant over a full length of a former between a first end and a second end, applying a second coat of coagulant proximate said second end by spraying said second coat extending less than said full length of said forming, and applying rubber material to said former.
9 . The method of claim 8 , further comprising
applying said coagulant by spraying.
10 . The method of claim 8 , wherein said rubber material is nitrile rubber.
11 . The method of claim 8 , wherein said rubber material is latex rubber.
12 . The method of claim 8 , wherein said former forms gloves.
13 . A method for making articles, comprising
dipping a former into coagulant, the forming having a first end and a second end, said first end placed into said coagulant before said second end, removing said former from said coagulant, applying a second material to said former and dipping said former into rubber material.
14 . The method of claim 13 , wherein said second material produces a colored band on said glove.
15 . The method of claim 13 , wherein said second material is a changeable indicator.
16 . The method of claim 13 , further comprising combining said second material with coagulant before application.
