  • Apparatus and method for cross-directional stretching of polymeric film and other nonwoven sheet material and materials produced therefrom
    Patent number: 6368444
    Abstract: A method for stretching nonwoven sheet material in the cross-machine direction includes coursing a nonwoven sheet material through a deformable nip, the nip being formed between two rotating stretch surfaces having intermeshing peaks and troughs, the surfaces of the peaks and troughs being covered with a deformable material, and contemporaneously pressing the stretch surfaces together while rotating them, such that as the nonwoven material travels through the nip, the nip deforms from an initial flat formation into a convoluted formation.
