Abstract

La presente brinda un aparato y métodos para estirar una o más zonas de una tela anisotropica y telas anisotropicas que incluyen una o más zonas estiradas. Cada una de las zonas estiradas en la tela se estira en la direccion transversal de la tela, es decir, la direccion transversal a la direccion descendente de la tela. El estiramiento se puede realizar de un modo continuo a medida que la tela avanza a través del aparato en la direccion descendente de la tela. El método para estirar una tela extensible en la direccion transversal se efectua generalmente, en una tela anisotropica extensible, sustancialmente continua. El estiramiento transversal de la tela se produce en una zona de orientacion establecida por una unidad de orientacion. La unidad de orientacion desplaza la tela fuera del plano de la tela, donde la tela se encuentra bajo tension, pero sin ninguna limitacion lateral. La tela se mueve sobre la unidad de orientacion donde el grado de orientacion es proporcional al desplazamiento en direccion transversal de una parte de la tela por medio de la unidad de orientacion. La tela anisotropica tiene una resistencia a la traccion en la direccion descendente de la tela mayor que en la direccion transversal; de modo tal que la tela es desplazada preferentemente en la direccion transversal de la tela por la unidad de orientacion. Ésta puede ser una resistencia a la traccion en la direccion descendente de la tela al menos 50% mayor que en la direccion transversal de la tela.This provides an apparatus and methods for stretching one or more areas of an anisotropic fabric and anisotropic fabrics that include one or more stretched areas. Each of the stretched areas in the fabric is stretched in the transverse direction of the fabric, that is, the transverse direction to the downward direction of the fabric. Stretching can be performed continuously as the fabric advances through the apparatus in the downward direction of the fabric. The method of stretching an extensible fabric in the transverse direction is generally performed, in an substantially continuous, anisotropic, extensible fabric. The transverse stretch of the fabric occurs in an orientation zone established by an orientation unit. The orientation unit moves the fabric out of the plane of the fabric, where the fabric is under tension, but without any lateral limitation. The fabric moves over the orientation unit where the degree of orientation is proportional to the transverse direction of a part of the fabric by means of the orientation unit. The anisotropic fabric has a tensile strength in the descending direction of the fabric greater than in the transverse direction; such that the fabric is preferably displaced in the transverse direction of the fabric by the orientation unit. This may be a tensile strength in the downward direction of the fabric at least 50% greater than in the transverse direction of the fabric.
