    摘要: A quick change pump assembly for an adhesive pumping system includes three main components: a manifold, a pump, and a motor. These components are secured to a subframe which is adapted to be detachably mounted on the mainframe of the system. The subframe with the three components mounted thereon is selectively movable between an operating position and a withdrawn position. In the withdrawn position, any of the components on the subframe may be replaced or repaired.

    摘要: A six-sided fibrous batting is coated with a nonwoven polymeric material by passing the batt sequentially through three coating stations. Four sides of the batt are coated in the first two stations and, after the batt is turned 90.degree., the final two sides are coated, completely encapsulating the batt in fibrous nonwoven coating.

    摘要: A meltblowing system with a modular die design and on-line monitoring of web properties is described. The modular die consists of individually fed side-by-side meltblowing units. Automated control of the polymer feed rates to the units have been shown to produce a web with excellent uniformity of basis weight. The die also features a valve assembly for minimizing polymer afterflow and die tip plugging.

    摘要: A polymer metl delivery system includes a preheated hopper, a high clearance auger, a gear pump, and provisions for delivering heat to the polymer. The resin is melted and fed to the auger and pumped to the gear pump and further pump to an extrusion die. Heat is added to the polymers from the hopper and throughout its course to the outlet connection for the extrusion die. The preheated in the hopper includes heat conductive fins. The system is particularly suited for use in combination with a meltblowing die.
