摘要： A glue coating apparatus is provided having a plurality of individual slit nozzles. Two faces are formed by an end face of a nozzle plate, in which feed channels open out, and by a clamping strip extending in front off the nozzle plate, these clamping a slit plate between them. The feed channels open into the regions of the slit plate which remain free between webs, so that the glue is channeled through the back of the slit plate. The webs and the individual glue streams are combined only immediately in front of an outflow point, to assure a uniform covering of the coating width, but prevent an overflow of glue from one slit nozzle into an adjacent one. The webs may also be tapered towards the outflow point, so that the individual glue streams can easily merge into one another. Separate glue pumps assigned to the individual slit nozzles can be provided in the form of a multiple pump, which can be designed as a gear pump, having a common central wheel and an appropriate number of planetary counter gear wheels arranged around the central wheel and generating cleanly separated feed streams.

摘要： An apparatus for applying hot thermoplastic stripe material to a solid surface. The apparatus comprises a pipe circuit including various means for storing and circulating stripe material, an applying device for said material, as well as an electronic control unit controlling the applying device. The applying device comprises a plurality of adjoining controllable gates. Each gate opening is of a width, i.e. the dimension perpendicular to the paper of FIG. 1, corresponding to a width module in the multi-stripe complex to be applied, whereas the height of the gate opening corresponds to the thickness of the applied material. The total width of the gates corresponds at least to the total width of the multi-stripe complex to be applied. Fluid-operated actuating means are present on the applying device, which serve to open and close the gates quickly. In this manner a possibility of a simultaneous applying of several marking stripes in a multi-stripe complex is obtained. Furthermore, the width of each stripe is easy to change. In addition, it is ensured that the beginning and the ending of each stripe is clear cut.

摘要： One end of a resiliently flexible valve stem is supported in a coaxially aligned, axially adjustable, socket means and mounts a ball at its other end for normally closing the seat of an outlet orifice of a nozzle. A portion of the valve stem intermediate its ends is operatively associated with a laterally reciprocable operator bar for selectively effecting flexure of the valve stem to displace the valve ball on its seat to open the orifice to release a fluid to be dispensed through the nozzle. A plurality of such valve assemblies are actuable by a common operator bar and the adjustment means of each valve can be selectively manipulated to render one or more of the valves inoperable to establish a desired pattern of flow of fluids from the valves which remain operable, or to vary the time sequence of operation of the valves proportionally to the degree of adjustment of the individual valves, or to vary flow rates.BACKGROUND OF THE INVENTIONThe present invention relates generally to fluid dispenser valves.The invention appears to be of special utility in the manufacture of cardboard or paperboard containers in applying hot melt adhesives to the various flaps or other surfaces thereof. Accordingly, the invention will be described with particular reference to such application but without implying limitation to any particular type of fluid or work surface.In the manufacture of paperboard cartons, it is frequently desirable to apply a plurality of glue beads or stripes to a flap, for example, of the container or carton blank. For this purpose a variety of devices have heretofore been devised. Some of these, for example, Walker et al U.S. Pat. No. 3,088,433 and Fox U.S. Pat. No. 3,126,574, merely provide a plurality of parallel spaced outlet nozzles with a common manifold under the control of a single valve element, no one of the individual outlet orifices being individually adjustable or capable of being rendered inoperable. Other devices, for example, Blair U.S. Pat. No. 3,508,849, Craig U.S. Pat. No. 3,190,259, Ziemba U.S. Pat. No. 3,286,689, Lockwood U.S. Pat. No. 3,348,520 and Guthrie U.S. Pat. No. 3,420,208, disclose a variety of multiple nozzle glue guns having outlet orifices individual ones of which can be rendered inoperable in order to achieve a desired pattern of a desired number of glue stripes or the like. However, the prior devices are relatively complex, expensive and cumbersome in use, particularly in effecting changes from one glue pattern to another.The present invention provides a simplified, relatively inexpensive, normally closed valve structure, comprising a simple assembly of readily replaceable parts, that is readily externally adjustable to alter the open time of the valve or the flow rate of the fluid to be discharged through the outlet orifice, or to render the valve inoperable.The invention also provides a durable, yet inexpensive, ball valve seat structure that is extremely well adapted to withstand high temperature, high pressure usage.The invention further provides a multiple nozzle glue gun with individual valve elements having flexible stems actuable by a common operator, each of the valve elements having individually adjustable means to render selected ones of the valve inoperable for achieving a desired pattern of plurality of glue stripes with the other operable valves. Further, the pattern is variable, not only with respect to the number of the array of nozzles remaining in actuable condition but, also, in a manner to vary the time sequence of operation of the valves so that, for example, one of the nozzles will delivery a shorter bead or stripe of glue then an adjacent nozzle. In yet another mode of adjustment of the multiple nozzle fluid dispenser of this invention, the flow rate of one or all of the nozzles can be adjusted readily.A full understanding of the invention, and of its further objects and advantages, will be had from the following description of a presently preferred embodiment thereof. It will be understood that this description, and the accompanying drawings which form part of it, are intended only as illustrative and not as a limitation upon the scope of the invention.

摘要： A retaining system for a solenoid assembly of a liquid adhesive dispensing system includes a quick-release mechanism configured to secure the solenoid assembly in place. The quick-release mechanism engages an air tube of the solenoid and thereby secures the entire solenoid assembly to a manifold. The quick-release mechanism can release the solenoid, facilitating easy removal of the entire solenoid assembly, by a simple turning, pushing, or pulling action on the quick-release mechanism. The released solenoid can then be removed and replaced, thereby minimizing downtime caused due to the replacement of a faulty solenoid.

摘要： A dispenser for dispensing liquid material while attenuating the liquid material or controlling the pattern of the liquid material with process air has a plurality of process air passages for providing process air to one or more liquid dispensing modules or nozzles. The flow rate of process air provided to one or more of the modules or nozzles may be separately controlled to be different from the flow rate provided to other modules or nozzles on the dispenser. Accordingly, the flow rate provided to each module or nozzle can be optimized to accommodate a particular dispensing nozzle or die.
