Liesee V. water could flow out of the hats or opening eggs at a point remote from the V. salt gap or be removed therefrom. In other designs, eyepieces were used "in which the lower press roller has a perforated jacket" which revolves over a stationary suction box which is attached in the area of the gap.

The effect of the pressure under the pressure in the order of magnitude "that it occurs in real prea &en" can better be grounded in relation to the present invention by comparing the hollow volume of typical tissue «without pressure and under such stress». If a ground thread 10 * atm similar to the one described in the first example is woven from multi-ply Uylon warp yarns which have a (iewieb't of 313 t> rasaaC ^ 330 e ^ air per 91 _V 4 m (100 yards) and multi-ply weft yarns which have a weight of 187 B (2800 grains) per 91 »4 m (100 yards), the count of the warp being 22.4 ends per 2.54 cm and the count of the weft 28.6 increments per 2.54 cm, with a total volume without pressure of 340 1 (12 cubic feet)

(10 cubic feet) per 279 a ² (3000 square feet). In this fabric, relatively coarse yarns were wasted, on the order of 0.762 mm (0.03 inches) lurchceseer and the fabric was relatively open, that is, the spacing between the yarns in the woven state was a size of 0.25 mm (0.01 inches).

As was admonished above, the tissue still had a void volume which was only a little less than 169.8 liters (6 cubic feet) per 279 a ² (3000 square feet).
