Abstract: Apparatus for providing an air cushion to support web material during turning thereof and including means defining two plenums providing a flow path for pressurized gas prior to the gas exiting from a slit adjacent a generally curved fluid flow attachment surface. The dual plenum arrangement results in an even air distribution at the location of the slit thus contributing to web stability and control as the web floats on a cushion of air comprised of the pressurized air and ambient air along the generally curved fluid flow attachment surface due to the Coanda effect.

Abstract: A method and system are provided for dispersing a plurality of closely associated filaments so that the dispersed filaments are capable of being deposited, in a random, convoluted pattern, on a moving web-forming surface to form a high machine-direction strength nonwoven product. The filaments are preferably dispersed by impinging same against a fluid-dynamically-assisted, contoured deflection means, preferably comprising a curved, downwardly inclined deflection element which is continuously traversed, generally codirectional with the filament flow, by a stream of air.

Abstract: An improved system for directing a web of flexible material to a predetermined location, and more particularly, a system for directing the end or tail of a moving web into threading engagement with rolls forming a nip or the like. In this system a gas such as air is directed through a restricted opening under pressure whereupon it attaches itself to a flow attachment surface due to the "Coanda effect", so that it entrains ambient air and the moving web tail. In a preferred form of the system, after the web tail has been entrained and conveyed a predetermined distance, a substantial portion of the combined flow of the entraining gas and the entrained ambient air are diverted off toward a different direction. At the location of diversion, restraining means is provided for preventing the web tail from moving with such substantial portion of combined flow. Another aspect of the invention resides in orientation of the restricted opening and flow attachment surface so that the web entrained thereby defines a concave path. Still another aspect resides in utilizing two Coanda nozzles in the system, the first of which is positioned to throw the web to the second across an open space of sufficient magnitude to dissipate a substantial portion of the gaseous flow from said first nozzle so that it does not interfere with operation of the second nozzle.
Abstract translation: 一种用于将柔性材料的纤维网引导到预定位置的改进的系统，更具体地，涉及用于将移动的纤维网的端部或尾部引导成与形成辊隙等的螺纹接合的系统。 在该系统中，诸如空气的气体在压力下被引导通过限制开口，由此由于“柯恩达效应”而将其附接到流动附着表面，使得其夹带环境空气和移动的网尾。 在系统的优选形式中，在卷筒纸尾部被夹带并输送预定距离之后，夹带气体和夹带的环境空气的组合流的大部分被转向不同的方向。 在转向的位置处，设有限制装置，用于防止卷筒纸尾部以相当大的组合流量部分移动。 本发明的另一方面在于受限制的开口和流动附接表面的取向，从而夹带的纸幅限定了凹形路径。 另一方面在于利用系统中的两个柯安达喷嘴，其中第一个喷嘴定位成将幅材扔到第二个穿过足够大小的开放空间，从而从所述第一喷嘴中散出大部分的气流， 不干扰第二喷嘴的操作。
