Rainproof ventilated plastic sheet material for rainwear and method of making same
Abstract
Abstract A RAINPROOF, VENTILATING MATERIAL IS PROVIDED UTILIZING TABS BENT AT THE LOCATION OF SLITS IN THE MATERIAL TO PROVIDE SHIELDED VENTILATION. THE MATERIAL ADJACENT EACH SLIT IS BENT TO FORM A PAIR OF FINGERNAIL-SHAPED TABS, THE DIRECTION OF THE PROJECTION OF ONE MEMBER OF THE PAIR FROM THE SURFACE OF THE MATERIAL BEING OPPOSITE THAT OF THE OTHER. THE PAIRS OF TABS ARE ALIGNED IN ONE DIRECTION, SO THAT THE TABS IN THAT ONE DIRECTION ALTERNATE IN THEIR DIRECTION OF PROJECTION, THUS, WHEN PROPERLY ORIENTED SHIELDING THE LOWER TABS BY THE UPPER TABS. THE MATERIAL IS FORMED FROM A SUBSTANCE WHICH MAY BE SUBJECTED TO MOLDING OR DEFORMING CONDITIONS, AND, WHICH, WHEN MOLDED TO THE DESIRED SHAPE MAY BE SUBJECTED TO SETTING CONDITIONS TO RETAIN THAT SHAPE PERMANENTLY. THE TABS ARE PERMANENTLY FORMED BY CUTTING THE SLITS AND BENDING THE TABS WHILE SUBJECTING THE MATERIAL TO MOLDING CONDITIONS, AS FOR EXAMPLE BY HEATING AND THE SETTING THE MATERIAL, AS FOR EXAMPLE BY COOLING.
