摘要： Nozzle apparatus of the over-pressure type for handling web material includes a nozzle box having a nozzle carrying surface which is curved towards the interior of the box to define a recess in the direction of web run and a pair of opposed nozzle slots located so that gas jets issuing therefrom follow the nozzle carrying surface in opposite directions with respect to each other so as to meet in the region of the curved recess to form a tranquilization zone. In this manner an air cushion is formed for the web which extends over a considerable distance in the direction of the web run to carry the web.
摘要翻译：用于处理幅材材料的过压型喷嘴装置包括具有喷嘴承载表面的喷嘴箱，喷嘴承载表面朝向盒的内部弯曲，以限定纸幅运动方向上的凹部和一对相对的喷嘴槽，从其发出的气体喷射沿着喷嘴承载表面相对于彼此相反的方向，以便在弯曲的凹部的区域中相遇以形成宁静区。以这种方式，形成用于幅材的气垫，其在幅材运行方向上在相当长的距离上延伸以承载幅材。

摘要： Nozzle apparatus for airborne paper web dryers of the non-impingement or underpressure type including a blow box member defined by top web supporting and bottom wall portions and back and front wall portions. The front and top supporting wall portions are interconnected by a curved guide surface and an upwardly directed nozzle is provided on the front wall portion spaced below the entry edge plane of the guide surface. The relative values of the width of the nozzle gap and the radius of curvature of the curved guide surface are such that the gas flow exiting from the nozzle follows a portion of the guide surface and departs therefrom prior to the exit edge plane of the guide surface. The upper surface of the top supporting wall of the blow box defines a small angle with the running plane of the web.

摘要： An air-directing device for directing air to the multiple cylinder dryer of a paper machine includes members for blowing dry air into the vicinity of the web at those points where the evaporation of water from the web is strongest. This reduces the humidity in such regions and promotes the evaporation of water from the web. The points are the initial parts of the cylinder intervals after contact with the web. The air-directing device is so placed, and its air-blowing members are so disposed and directed, that the air blown out from such members is directed into the clefts defined by the surface of the drying cylinder and the paper web. This achieves a pressure effect in the clefts. The air-blowing members are primarily used in connection with single fabric conduction in pockets on the side of the web to urge the web fast to the fabric and are preferably disposed on a doctor beam or in conjunction therewith.
摘要翻译：用于将空气引导到造纸机的多缸干燥器的空气引导装置包括在来自幅材的水的蒸发最强的点处将干燥空气吹入到纸幅附近的构件。这降低了这些区域的湿度，并促进了水从网上的蒸发。这些点是与网络接触后的气缸间隔的初始部分。导风装置如此放置，并且其空气吹送构件被布置和定向，使得从这些构件吹出的空气被引导到由干燥筒和纸幅的表面限定的缝隙中。这实现了裂缝中的压力效应。吹风构件主要用于在腹板侧面的口袋中的单一织物传导，以将织物快速地推向织物，并且优选地布置在刮刀梁上或与其结合。
