A glue applying mechanism of an edge banding machine for applying glue to an oblique surface and a vertical surface of a workpiece includes a base including a glue tub, and a glue applying unit rotatably disposed on the glue tub and including a glue shaft and an obliquely glue applying member connected to the top end of the glue shaft and having a glue applying surface which is a tapered surface with a wide top and a narrow bottom. At least the partial top of the glue shaft and the glue applying surface are exposed outside the glue tub. The glue applying unit is rotatable to extract the glue in the glue tub to the outer surface of the glue shaft and the glue applying surface, enabling the glue to be applied to the oblique and vertical surfaces of the workpiece simultaneously by only one glue applying mechanism.

A glue application device is provided for the application of glue to a short side of a plate-shaped workpiece. Such a glue application device can be included in a coating machine.

A device for removing hot-melt adhesive from a rotating, vertically-arranged roller (1), comprising: a hollow, preferably hollow cylindrical, scraper (2), characterized in that the scraper (2) comprises an opening (6) on the circumferential surface thereof along the longitudinal axis, at which opening a strike plate (3) that protrudes radially outward is arranged, and wherein the strike plate (3) is arranged such that it can be brought into a position for removing adhesive from the roller (1) and can convey the removed adhesive towards the circumferential inner side of the scraper (2).

An apparatus for dispensing a flowable material is disclosed. The apparatus comprises a rotary actuator, a reservoir, containing a hydraulic fluid, a piston, movable inside the reservoir, a linear actuator, coupled to the piston, a gear train, coupling the rotary actuator with the linear actuator, and a flowable-material dispenser, hydraulically coupled with the reservoir.

An optical device coating assembly is provided. The optical device coating assembly includes a substrate support operable to retain an optical device substrate. The coating assembly further includes a first actuator connected to the substrate support. The first actuator is configured to rotate the substrate support. The coating assembly includes a holder configured to hold a coating applicator against an edge of the optical device substrate when the optical device substrate is rotated on the substrate support and a second actuator operable to apply a force on the holder in a direction towards the substrate support. The second actuator is a constant force actuator.

A paint applicator assembly includes a frame having a base. The base has a forward side, a first lateral side, and a second lateral side opposite the first lateral side. A light assembly is supported by the frame. The light assembly includes a printed circuit board having a forward side portion positioned proximate the forward side of the base. The light assembly further includes a plurality of light sources supported on the printed circuit board. The plurality of light sources includes a first light source and a second light source positioned on the forward side portion. The first light source is configured to direct light along a first direction, and the second light source is configured to direct light along a second direction that is different than the first direction.

A high viscosity material is discharged in the form of a continuous thread from an application nozzle toward an end of a workpiece and a space S on the side of the workpiece so that the high viscosity material in the form of the thread adheres to a front surface of the workpiece and the high viscosity material discharged in the form of the thread into the space on the side of the workpiece pivots around an edge of the workpiece to a back surface of the workpiece and adheres to the back surface of the workpiece. The high viscosity material can thus be applied to both the front and back surfaces of the workpiece in one step of discharging the high viscosity material only from the front surface side of the workpiece.

Nozzles are provided, for applying setting resins onto the edge of a panel, in some embodiments the cut edge of a panel such as a honeycomb panel. The nozzle comprises a connector portion and an application head, wherein the application head comprises: a) a supporting wall, and b) a curved finish wall joining the supporting wall along an edge at an angle of greater than 92 degrees and less than 120 degrees. In some embodiments, the curved finish wall has a curve radius which remains between 1.0 and 7.0 cm throughout the length of the curved finish wall. In some embodiments, the curved finish wall has a trailing edge profile which is smoothly curved and a leading edge profile which is scalloped. In addition, methods of applying a setting resin onto the edge of a panel are presented.

A slot applicator nozzle has a body with a dispensing end sized to fit within a slot of an object. The body defines a channel therethrough with an outlet at the dispensing end. The dispensing end includes a leading contact surface and a trailing contact surface separated from each other by a gap. Both the leading and trailing contact surfaces are configured to contact a bottom surface of the slot as the body is moved along the slot in an application direction. The trailing contact surface is disposed between the leading contact surface and a rear end of the body. The outlet of the channel is configured to emit a flowable substance rearward of the trailing contact surface onto the bottom surface of the slot as the body is moved in the application direction.
