Definitions

  • the present invention concerns a glue applicator, especially for endpaper-gluing machines, with a glue reservoir and a rotating glue wheel partially submerged in the reservoir, the wheel removing glue from the reser voir on its peripheral area as it turns.
  • the present invention proposes the construction of an easily adjusted glue applicator.
  • the glue applicator is characterized in that the glue reservoir is made in the form of a flow-through reservoir, through which glue flows constantly during the operation, and in that the glue wheel is located outside, with a segment of its edge inside the reservoir and in the glue system.
  • FIG. 1 is a cross sectional view of a portion of a glue applicator taken alone line I-I in FIG. 2.
  • FIG. 2 is a top plan view of a section through a glue I applicator according to FIG. 1, and
  • FIG. 3 is a cross sectional view taken along the line 11-11 of FIG. 1.
  • Bracket 1 also contains a tube 10, preferably of plastic, carrying at its upper end a connecting sleeve 12 to accept a hose.
  • This hose extends from a feed pump, especially a hose pump (not shown) to the tube 10.
  • the hose pump draws glue from a central glue reservoir and feeds it via the feed hose to connecting sleeve 12 and into tube 10, whose outlet 14 runs back into the central reservoir.
  • Shaft 7 carries a glue wheel 17, whose perimeter 18 serves to pick up the glue and apply it to the product to be glued.
  • An adjustable sleeve 19 with a slit 20 is rotatably mounted on tube 10, the width and length of said slit 20 being greater than a slit 22 in tube 10.
  • Slit 22 is made so that the glue wheel 17 touches the tube with its face, the tube preferably being made of plastic, so that the glue wheel 17 can turn unimpeded through slit 22, without glue wheel 17 actually picking up glue from tube 10 on both its faces.
  • lever 24 can be turned to adjust the length of slit 22 in the tube, i.e., slit width 21, so that .the rim 18 of glue wheel 17 picks up the desired amount of glue.
  • Glue wheel 17 is connected to drive gear 6 by shaft 7, and is held on the shaft by a washer 27 and knurled head screw 28.
  • the glue applicator works as follows: the pump draws the appropriate amount of glue from the central reservoir and feeds it into tube 10 via the connecting hose and connecting sleeve 12. Here the glue 26 runs down through inclined tube 10 and leaves the latter through outlet 14, to flow back into the central reservoir.
  • the rotating glue wheel 17 rests inside tube 10 so that a portion of the wheel (as can be seen in FIG. 3) dips into the downward flowing mass of glue 26, and so that a portion of the glue remains suspended on glue wheel 17. Since the thickness of the glue wheel 17 and the slit width of tube 10 are adjusted to one another, the volume of glue carried away on the face of the glue wheel 17 as the wheel emerges from tube 10 is wiped off by the slit edges, except for the amount that adheres to the rim 18 of the glue wheel. By rotating the adjusting sleeve 19, the slit width 21 (and hence the amount because the above-described glue applicator is not under pressure. Hence a normal, smoothflowing glue can be used.
  • Aglue applicator for applying glue to a workpiece comprising:
  • a reservoir comprising a generally inclined hollow elongated member having upper and lower ends through which glue may constantly flow having an inlet at the upper end of said member for the glue whereby the glue flows downwardly by gravity through the member along one side thereof; a first slot located in said one side of said member such that a portion of said slot extends below the surface of the glue when glue is flowing in said reservoir; and an outlet at the lower end of said member for that portion of the glue which is not removed out of said first slot; 4 means connected to said inlet of said reservoir for constantly flowing the glue therethrough in a shallow stream such that said stream of glue substantially covers said first slot while occupying only a small portion of the total inner volume of said reservoir, whereby approximately no static head is produced and substantially all the pressure exerted by the glue on said first slot is the dynamic pressure of the glue flowing past said first slot; and applicator means comprising a glue wheel, having an outer periphery, rotatably mounted externally of said reservoir with a portion of said outer periphery partially extending into said slot to
