摘要： An electrostatic dispensing system for dispensing flowable liquid material onto a moving substrate. The electrostatic dispensing system includes multiple liquid dispensers that are aligned along a common axis and supported in spaced, non-contacting relationship on one side of the moving substrate. Each of the liquid dispensers includes a valve to control the flow of fluid through the dispenser. An electrostatic field generator is supported in spaced, non-contacting relationship on the opposite side of the moving substrate to generate an electrostatic field through the moving substrate. The electrostatic field operates to attract flowable liquid material from dispensing outlets associated with the multiple liquid dispensers as a series of spaced, continuous streams or beads which intersect a surface of the moving substrate facing the liquid dispensers. The beads of flowable material are deposited on the surface of the moving substrate in a series of uniform, continuous beads which are formed generally parallel to a direction of travel of the moving substrate. Methods of electrostatically dispensing flowable material onto a moving substrate are also disclosed.

摘要： A method and apparatus for controlling the gas content of dispensed hot melt thermoplastic adhesive foam. Air or another relatively inert gas is mixed with molten thermoplastic adhesive, and the mixture is pressurized to form a gas and molten adhesive "solution". When the molten adhesive and gas "solution" is dispensed at atmospheric pressure, the gas is released from "solution" and becomes entrapped in the adhesive in order to form a homogeneous closed cellular adhesive foam. In order to control the gas content of the dispensed adhesive and gas "solution", in accordance with one preferred embodiment, the pressure drop across a restriction in the flow path of the solution is sensed, and a control circuit controls the addition of gas to the adhesive to maintain the sensed pressure drop at a desired level. Other sensing techniques can be used to measure a parameter of the dissolved gas/molten adhesive single phase liquid solution which is correlated to the dissolved gas content of the solution and substantially independent of the molten adhesive content thereof, such as measuring the transmittance of infrared radiation through the gas/adhesive single phase solution at a wavelength relatively heavily absorbed by the gas and unabsorbed by the adhesive.
摘要翻译：一种用于控制分配的热熔性热塑性粘合剂泡沫体的气体含量的方法和装置。将空气或另一相对惰性的气体与熔融的热塑性粘合剂混合，并将混合物加压以形成气体和熔融粘合剂“溶液”。当熔融粘合剂和气体“溶液”在大气压下分配时，气体从“溶液”中释放并被夹带在粘合剂中以便形成均匀的闭孔多孔粘合剂泡沫。为了控制分配的粘合剂和气体“溶液”的气体含量，根据一个优选实施例，感测溶液流动路径中的限制的压降，并且控制电路控制将气体添加到粘合剂以将感测到的压降保持在期望的水平。其他检测技术可用于测量溶解气体/熔融粘合剂单相液体溶液的参数，其与溶液的溶解气体含量相关，并且基本上与其熔融粘合剂含量无关，例如测量红外辐射的透射率通过气体/粘合剂单相溶液以较高的吸收气体的波长并被粘合剂吸收。

摘要： A system for dispensing liquid material with different configurations of air assisted fiberization or filament movement (e.g., meltblowing, controlled fiberization). In particular, front access for mounting a selected nozzle only requires adjustment of one lever and one fastener. Features of the lever and nozzle allow assisted ejection of the nozzle, even when the nozzle has become adhered to a die body through use. In addition, a nozzle mounting surface of the die body provides a universal interface to the various types of nozzles. An air cavity in the die body and air troughs in selected types of nozzles balance and adjust air flow.

摘要： A heated air manifold of reduced physical dimensions for heating process air for use in dispensing heated liquids, such as hot melt adhesives. The heated air manifold includes at least one heating element and an air plenum having an air inlet and an air outlet. The dimensions of the air plenum are optimized for providing a compact heated air manifold for use in various adhesive dispensing systems, such as systems assembled from modular adhesive manifold segments, while retaining the ability to heat the process air in the air plenum to a desired application temperature. The heated air manifold may include a thick film flat heater disposed in the air plenum. The air plenum may have multiple individual segments winding throughout the volume of the heated air manifold.

摘要： A liquid dispensing module and nozzle or die tip for discharging at least one liquid filament. The nozzle includes a wedge-shaped member having a pair of side surfaces converging to an apex. A liquid discharge passage extends along an axis through the wedge-shaped member and through the apex. The wedge-shaped member extends in a radially asymmetrical manner around the liquid discharge passage. Four air discharge passages are positioned at the base of the wedge-shaped member. At least one air discharge passage is positioned adjacent each of said side surfaces and each of the air discharge passages is angled in a compound manner generally toward the liquid discharge passage and offset from the axis of the liquid discharge passage.
