Abstract: A method for producing visco-elastic fluidic material flows by drawing a visco-elastic fluidic material with corresponding separate second fluid flows associated therewith to form a visco-elastic fiber vacillating in a repeating, generally omega-shaped pattern having a bowed portion with first and second side portions that first converge toward each other and then diverge outwardly in generally opposing directions. In one operation, the visco-elastic fiber vacillating in the repeating, generally omega-shaped pattern is an adhesive material deposited onto woven and non-woven fabric substrates and stretched elongated elastic strands in the manufacture of a variety of bodily fluid absorbing hygienic articles.

Abstract: A parallel plate nozzle for extruding visco-elastic fluidic materials, useable in the manufacture of non-woven materials, and method therefor dispenses a plurality of first and second fluids from a corresponding plurality of first and second orifices to form first and second adjacent fluid flows. The first fluid flows are drawn and attenuated by not more than one corresponding second fluid flow at a second velocity greater than a first velocity of the first fluid flow to form corresponding first fluid filaments, which are preferably relatively continuous and vacillated chaotically. The first and corresponding second fluid flows are spaced as closely as possible to maximize filament drawing efficiency, and adjacent first fluid orifices are spaced sufficiently apart to prevent merging of the first fluid flows prior filament formation.
Abstract translation: 用于挤出可用于制造无纺材料的粘弹性流体材料的平行板喷嘴及其方法从相应的多个第一和第二孔口分配多个第一和第二流体以形成第一和第二相邻流体流 。 第一流体流以不大于一个对应的第二流体流以大于第一流体流的第一速度的第二速度被拉伸和衰减，以形成对应的第一流体长丝，其优选地相对连续并且混沌地摆动。 第一和相应的第二流体流动尽可能地尽可能地间隔开，以最大限度地提高丝丝拉丝效率，并且相邻的第一流体孔口间隔足够大，以防止在丝线形成之前第一流体流的汇合。

Abstract: A method and apparatus for evaluating a paint filter. The apparatus includes a duct, air supply, spray gun, target, filter holder and particle sensing device. The spray gun and target are disposed within the duct to simulate actual paint spraying conditions, including production of overspray. The filter holder maintains a test filter downstream of the target such that overspray interacts with the test filter. The particle sampling device is associated with the filter holder and is configured to sense and provide information indicative of paint filter efficiency and preferably includes a time-of-flight particle measurement instrument. During use, the spray gun sprays paint particles at the target. Overspray from the target interacts with the test filter. The particle sampling device senses data upstream and downstream of the filter, from which a filter evaluation is made.
Abstract translation: 一种用于评估涂料过滤器的方法和装置。 该设备包括管道，空气供应，喷枪，目标，过滤器支架和颗粒感测装置。 喷枪和靶设置在管道内，以模拟实际的喷漆条件，包括过喷的生成。 过滤器保持器在测试过滤器的下游保持测试过滤器，使得过喷器与测试过滤器相互作用。 颗粒采样装置与过滤器保持器相关联，并且构造成感测并提供指示涂料过滤器效率的信息，并且优选地包括飞行时间颗粒测量仪器。 在使用过程中，喷枪在目标上喷涂油漆颗粒。 来自目标的超喷射与测试过滤器相互作用。 颗粒采样装置感测过滤器的上游和下游的数据，从中进行过滤器评估。

CPC classification number: F24H3/0405 , B05C5/001
Abstract: An air pre-heating apparatus useable for pre-heating air supplied to one or more hot melt adhesive dispensing nozzles mounted on an adhesive supply manifold. Air is supplied from an air supply inlet on an outer portion of an outer heating member to an air supply outlet on an inner heating member having a heater therein. The outer heating member formed of a plurality of laminated plates having one or more air flow paths, which include preferably a serpentine air flow path portion that increases the residence time of the air therein. The air is supplied through the apparatus against a decreasing temperature gradient whereby heat is increasingly added thereto before the air is supplied to the nozzles. The apparatus is preferably thermally isolated from the manifold to permit maintaining the pre-heating apparatus at a temperature different than a temperature of the manifold.
Abstract translation: 一种空气预热装置，其可用于预先供应给安装在粘合剂供应歧管上的一个或多个热熔胶分配喷嘴的空气。 空气从外部加热构件的外部的供气入口供给到其中具有加热器的内部加热构件上的空气供应出口。 由具有一个或多个气流通道的多个层叠板形成的外部加热构件，其优选地包括增加空气在其中的停留时间的蛇形空气流路部分。 空气以降低的温度梯度供应，从而在将空气供应到喷嘴之前越来越多地加入其中。 该装置优选地与歧管热隔离以允许将预热装置保持在不同于歧管温度的温度。

CPC classification number: B05B15/00
Abstract: In a fluid spray gun, the fluid nozzle is threadedly attached to the gun body and is covered by an air cap and threaded retaining ring. A latching mechanism is placed in the gun body and removably latches the toothed nozzle in place to prevent rotation due to friction from the air cap and retaining ring. The latch is held in place by the air cap and/or retaining ring but is easily disengaged when the air cap and retaining ring are removed.
Abstract translation: 在流体喷枪中，流体喷嘴螺纹连接到枪体上并被空气帽和螺纹保持环覆盖。 锁定机构被放置在枪体中并且可移除地将齿形喷嘴锁定就位，以防止由于空气帽和保持环的摩擦而旋转。 闩锁通过空气帽和/或保持环保持在适当位置，但是当空气盖和保持环被移除时容易脱开。
