Abstract
The invention resides in a compression membrane for wringing liquid out of an object to be compressed, characterized in that its marginal portion whose width is of the order of 15%-35% of the width in the radial direction of the membrane body is made smaller in stretchability than the other portion, whereby no tear of the object to be compressed does not tear during the dehydration thereof.
Claims5
A compression membrane constructed for wringing liquid out of a textile product, said membrane having a membrane body with a center, a radius, a marginal peripheral portion in a radial direction from said center, and a remaining portion, wherein said marginal peripheral portion has a width in said radial direction of 15-35% of said radius, and said marginal peripheral portion has a higher degree of rubber hardness, and therefore a smaller degree of stretchability, than that of said remaining portion, and a portion of said marginal peripheral portion adjacent to said remaining portion has substantially the same thickness as said remaining portion, said membrane being constructed such that during the wringing said marginal peripheral portion will contact the textile product to a substantial extent without exerting tensile force on the textile product.
