  • Method for forming a glove using a folded glove form
    Patent number: 5833911
    Abstract: A method for forming a glove in an elastomer deposition process employs a folded glove form. The form has a hand forming portion having palm and finger forming portions. The finger forming portions terminate in distal tips and the cuff forming portion terminates in a terminal end for forming the cuff opening. The form is folded so that finger forming portion distal tips and the cuff forming portion terminal end lie in separate planes and in facing relationship to one another. To form the glove, the form is vertically oriented and dipped into a bath of elastomer with both the cuff forming portion terminal end and the finger portion distal tips facing upwards.
