摘要： An apparatus for melting and dispensing thermoplastic material comprising a hopper, a grid melter, a reservoir and a pump. At least a portion of the hopper is enclosed within a shroud so as to define an air flow chamber around the lower end of the hopper. Air is forced through this chamber when the apparatus is in use so as to cool the hopper and prevent molten material from backing up into the hopper.

摘要： A slot coating die (10) is provided, comprising an upper die half (12) and a lower die half (14) attached together with a shim (16) disposed therebetween, each die half extending along an axis (18) and having a front and a back. The front of the upper die half includes a movable lip insert (22) extending substantially the entire width thereof and movable with respect to the upper die half toward and away from the front of the upper die half in a direction generally perpendicular to the axis. At least one adjustable die opening (20), which is adjustable independently of the movable lip insert, is defined by the upper and lower die halves and the shim plate disposed therebetween. A plurality of push-pull bolts (30) provide a coarse adjustment mechanism for adjusting the relative positions of the lower and upper die halves with respect to each other in a direction generally parallel to that in which the movable lip insert may be moved. A plurality of springs (128) loaded screws (124) spaced along the width of the upper die half provide a fine adjust mechanism by which the lip insert is made movable in that direction.

摘要： Apparatus for intermittently dispensing substantially constant cross sectional thickness beads of molten hot melt material comprising a service block connected to a pressurized source of molten hot melt material, a dispensing gun module, and a return module. Both the dispensing gun module and the return module are mounted upon the service block, the connection being such that the inputs to both modules are received from the service block. Both the dispensing gun module and the return module have valve elements therein operable to open flow through the dispensing gun module and the return module alternatively so that the pressure of adhesive supplied to the dispensing gun module remains constant as hot melt material is dispensed from the dispensing gun module intermittently.

摘要： A method and apparatus are disclosed for controlling the density of dispensed hot melt thermoplastic adhesive foam in order to assure uniform foam characteristics. In order to create the hot melt adhesive foam, air or any relatively inert gas is mixed with the thermoplastic adhesive while the adhesive is in the molten state, and the mixture is then pressurized so as to force the gas into solution with the molten adhesive. As the molten adhesive/gas solution is dispensed at atmospheric pressure, the gas is released from solution and becomes entrapped in the adhesive so as to form a homogenous closed cellular adhesive foam. According to the practice of this invention, the supply of gas is periodically discontinued so as to prevent an excess volume of gas from being admixed with the molten adhesive whenever foamed adhesive is not being dispensed, thereby stabilizing the density of the adhesive foam.
摘要翻译： 公开了一种用于控制分配的热熔热塑性粘合剂泡沫的密度以确保均匀的泡沫特性的方法和设备。 为了产生热熔粘合剂泡沫，当粘合剂处于熔融状态时，将空气或任何相对惰性气体与热塑性粘合剂混合，然后将混合物加压，以迫使气体与熔融粘合剂溶液。 当熔融粘合剂/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。 根据本发明的实践，周期性地停止供应气体，以防止在不分配发泡粘合剂时，过量的气体与熔融粘合剂混合，从而稳定粘合剂泡沫的密度。

摘要： A gas/liquid mixer in which intermeshing gears are caused to rotate and establish mixing, by pressure of the fluids being mixed. The gears are mounted for rotation in a gear chamber and interengage in a meshing zone of the chamber. A gas is introduced into the chamber through a gas inlet which is adjacent to one end of the meshing zone. A liquid inlet enters the chamber between the gas inlet and an outlet which is positioned adjacent a second or opposite end of the mixing zone. The gears are rotated in the chamber by the introduction and expansion of the gas and liquid in the spaces between the gear teeth. Flow regulating means controls the gas/liquid ratio. The apparatus is useful, among other purposes, for mixing a soluble gas with molten hot melt adhesive, directly adjacent the nozzle of a dispenser for preparing a hot melt foam.

The screen assembly (200) supports the cylindrical screen in an operating axial position about a first axis (127), and includes (i) at least one guide wheel (206) engageable with the screen and (ii) a retractable support arm (238) pivotable about an axis (72) from a first position wherein the at least one guide wheel is engaged with the screen in the operating axial position, to a second position wherein the at least one guide wheel is disengaged from the screen. The heater hood assembly (300) assures an evenly heated outer surface of the screen.

摘要： A multi-orifice T-bar nozzle includes a nozzle body having a mounting plate adapted to connect to the body of a hot melt thermoplastic adhesive dispenser, and an internal adhesive flow path formed by an inlet at the top wall of the nozzle body adapted to receive adhesive from the adhesive dispenser, a number of outlets at the bottom wall thereof which extrude adhesive beads and a distribution passageway interconnecting the inlet and outlets. The nozzle body progressively tapers from the top, center portion thereof to its extremities, i.e., to the end portions and bottom of the nozzle body, so that the temperature differential between the adhesive entering the inlet of the nozzle body, and the adhesive discharged from the outlets, is minimized.

摘要： Apparatus for melting and dispensing thermoplastic material including a hopper for receiving solid thermoplastic material, a flow-through grid melter secured to the bottom of the hopper and a heated reservoir mounted beneath the grid melter. The reservoir has a bottom discharge opening through which molten thermoplastic material is supplied to a pump. To control the temperature of molten material supplied to the pump, there is a deflector shield over the bottom discharge opening of the reservoir. This shield has downwardly and outwardly sloping top surfaces operable to force molten material falling onto the shield to flow outwardly over the top surface of the shield and then downwardly and inwardly over the top surface of the bottom wall of the reservoir before flowing into the outlet opening of the reservoir. To input desired temperatures for the grid and reservoir into the apparatus and to read out temperature data, there is a control console mounted atop the housing of the apparatus. This console is pivotally and vertically adjustable and facilitates operator interface with the apparatus.
