Abstract:
An apparatus for melting and dispensing thermoplastic material is provided that includes an un-heated hopper having an inlet for receiving particles of a thermoplastic material and an outlet for discharging the particles and a heated manifold including at least one cavity formed therein and having an inlet and an outlet the inlet communicating with the outlet of the hopper for receipt of the particles from the hopper. The hopper is disposed external of the heated manifold. The heated manifold is effective for melting the particles into molten thermoplastic material therein. The apparatus further includes a pump having an inlet in fluid communication with the cavity. An outlet of the pump is in fluid communication with an inlet of a dispenser and an outlet of the dispenser is effective for dispensing the molten thermoplastic material therethrough.
Abstract:
An application head for applying a liquid medium, such as a hot melt adhesive or cold glue, to a substrate. The application head includes a housing (2) which forms a chamber (3) which is rotation-symmetric relative to an axis of rotation (A) and comprises a supply channel (4) and an outlet aperture (5) at one end, as well as a rotatingly attached control slide (6) which is supported so as to be rotatable around the axis of rotation (A). The control slide (6) which is positioned at an end face in the chamber (3) and closes same comprises at least one passage (15) to allow the through-flow of the adhesive medium from the chamber (3) into the outlet aperture (5).
Abstract:
A device for producing a foam material, comprising a gas supply line which is connectable at a first end to a gas source, a material supply line which is connectable at a first end to a material supply source, a material transporting device which is connected to a second end of the material supply line, and a mixing device into which material and gas may be introduced and in which they may be mixed together, and from which a homogeneous mixed foam is deliverable from an output orifice.
