Abstract: A labeling system where a cylindrical vacuum drum carries plastic labels at spaced intervals on its surface and a solvent applying gravure roll is held at a specific spacing from the drum and labels so that the labels will receive the solvent when they pass the rotating roll. The gap between the drum and the roll must be carefully controlled in order to be assured that the solvent is properly transferred. The gap is controlled by a fine adjustment of the platform on which the roll is mounted relative to the drum by a threaded rod moving a tapered surface of a reciprocable member in contact with a stop block mounted on the platform. The threaded rod threads through a stationary bracket and turns a shaft that threads into the member. The member is prevented from rotation so that rotation of the rod moves the member in one direction while rotation of the shaft moves the member in the opposite direction.

Abstract: The end portions of a flexible strip (46,48,50,52) are deflected from the path (54) of an automatic end cementer (10) along which the strip (46,48,50,52) is moved into engagement with cement appliers (62,94) spaced from the path (54). The weight of the unsupported leading end portion (92) causes the end (56) of the strip (46,48) to be deflected downwardly into contact with a cement applier (62) adjustably positioned below the path (54). The trailing end portion (58) is deflected upwardly by changing the direction of the path (54) for the strip (50,52) to lift the trailing end portion (58) from the path (54) into contact with a cement applier (94) adjustably positioned above the path (54).

The intermediate portion of the peripheral surface receives a mixture of paste and air from a spray nozzle which, in turn, receives the mixture from a conduit containing a mixer and a pump and having an intake end immersed in the supply of paste in the tank. The pump draws air or another gas into the conduit by way of a pipe upstream of the mixer, and the latter converts the supplied paste and gaseous fluid into a foam which is delivered to the orifice of the nozzle.

Abstract: An applicator for metering a desired amount of a liquid sizing onto moving glass filaments. In a first embodiment, a foam-covered roller is partially immersed in a reservoir of liquid sizing and is in contact with the smooth surfaced applicator roll. The foam-covered roller is driven in the same direction as the applicator roll and a puddle is formed above the roller/roll nip. The pressure exerted by the foam covered roller on the applicator roll and rate of rotation of the applicator roll determine the size of the puddle, which controls the amount of sizing applied to the glass filaments. A second embodiment employs an elastomeric reservoir which sits generally atop the applicator roll. A plurality of slots in the rotationally downstream side of the reservoir dispense the sizing onto the roll with the pressure between the elements and rate of rotation of the applicator roll, again, determining the application rate. The sizing is pumped through a closed loop to keep its temperature and viscosity more uniform.

Abstract: Most ribbon re-inking machines are not clean and convenient to use. The present machine is relatively clean to use because the ink reservoir is normally kept oriented so that leakage does not occur. Thus, the reservoir has an inlet which is sealed once ink has been added while an inking roller fits in an outlet on the same side as the inlet. Thus ink can only flow onto the roller when the reservoir and whole machine is inverted for use. An air inlet is provided on the other side of the reservoir from the outlet and roller and that inlet is opened when the reservoir is inverted. Only then will ink flow during rotation of the roller when a ribbon is moved over it.

A cleaning fluid introduced at the ends of the manifold flushes through those passages outboard of the dams and exits at the ends of the cavity to prevent build-up of glue in the shoe.

Abstract: A method for producing corrugated board utilizes a glue applying means constructed with an elongated shoe floatingly mounted alongside of and urged toward a glue applicator roll by a fluid controlled biasing means. A longitudinally extending depression in the shoe is substantially closed by the glue roll to define a glue cavity to which glue is fed by a positive displacement pump. The shoe is mounted so that the downstream end of the shoe is movable away from the glue roll automatically as required to permit glue to exit from the cavity at the same rate it is supplied thereto. This provides what is effectively a self-adjusting nozzle or fluid distribution slot extending the full length of the shoe and through which glue is forced from the cavity to form a thin layer of uniform thickness on the outside of the glue roll. The latter applies such thin layer of glue directly to the flute tip of a corrugated web for joining a liner web to the corrugated web.
