Abstract:
A system for applying a two-part adhesive to a substrate includes a prime mover for providing an output torque, a first pump connected to the prime mover for receiving the output torque, the first pump having an inlet and an outlet, a second pump connected to the prime mover for receiving the output torque, the second pump having an inlet and an outlet, a first compound in communication with the inlet of the first pump, a second compound in communication with the inlet of the second pump, a first accumulator in communication with the outlet of the first pump, a second accumulator in communication with the outlet of the second pump, a first manifold in communication with the outlet of the first pump, and a second manifold in communication with the outlet of the second pump. A plurality of applicators is included.
Abstract:
A method of making an article having a substrate and two materials applied thereto includes providing a metered fluid dispensing system (100) having first and second supply sources for supplying first and second fluids, respectively, an output device (110) having at least one dispensing nozzle and at least two pumps (104, 106). The dispensing system is configured to selectively control the passage of the first and second fluids. The substrate (154) is conveyed past the fluid dispensing system in a machine direction and the first, or second, or first and second fluids are applied to the substrate in a plurality of segments, each segment having a volume per unit length and applied in a length in the machine direction to define a pattern, and in which wherein the pattern includes at least some areas in which the first or second fluid is present without the other fluid.
Abstract:
The invention relates to a dispensing process particularly for a sealing/adhesive product (14) which comprises at least one step of pumping the sealing/adhesive product to allow a step of distribution thereof onto at least one part to be sealed, such as for example a motor-vehicle mechanical component (5), an intermediate step of deaeration of the sealing/adhesive product, so as to optimize its distribution on the part to be sealed, is provided between the pumping step and the distribution step. The apparatus for dispensing the sealing/adhesive product (14) comprises elements (2) for feeding the sealing/adhesive product to elements (4) for distributing it onto at least one part (5) to be sealed and sealing/adhesive product deaeration means (3) which cooperate with the pumping and distribution elements for the uniform deposition of the sealant/adhesive on the part.
Abstract:
Apparatus for the production of an electric conductor provided with at least a layer of coating plastic material. The apparatus comprises: a head for the extrusion of an electric conductor; at least a main extruder having a first supply duct; at least an auxiliary extruder having a second supply duct; and a device for the selection and the diversion of the flows of coating plastic material. The selection and diversion device is provided, in turn, with at least a device for the exclusion of the auxiliary extruder; with a bypass duct between the first duct and the second duct; and with a flow-regulating diverter valve arranged in the intersection point between the first supply duct and a bypass duct connecting the first duct to the second duct.

Abstract:
The invention relates to a facility for depositing a film of ordered particles (4) onto a moving substrate (8), the facility being designed to allow the deposition, onto the substrate, of a film of ordered particles discharged through the particle outlet of a transfer area having a first width (L1). According to the invention, the facility further includes an accessory device (100) in the form of a deposition head for blocking said particle outlet and designed to allow the deposition, onto said substrate (38), of a film of ordered particles discharged via an end (62) of a particle transfer channel (56) of said deposition head, said end having a second width (L2) that is strictly smaller than the first width (L1).
Abstract:
Die Mischvorrichtung zum Vermischen von einer Binder-Komponente (A) und einer Härter-Komponente (B) zu einem pastösen oder flüssigen Mischgut für ein Gerät (100) zur Herstellung einer gebrauchsfertigen Spachtelmasse für die Verspachtelung von Oberflächen von Fahrzeugkarosserien, umfasst einen hohlzylinderartigen Statorteil (16) und einen in diesem konzentrisch um seine Längsachse (20) drehbar aufgenommenen Rotorteil (19), wobei die Mischkammer (14) zwischen dem Statorteil (16) und dem Rotorteil (19) ringspaltartig ausgebildet ist, und sich mehrere am Statorteil (16) angeformte erste Mischzähne (23) radial nach innen und mehrere am Rotorteil (19) angeformte zweite Mischzähne (24) radial nach außen in eine Mischkammer hinein erstrecken, um vermittels einer Rotationsbewegung des Rotorteils (19) im Statorteil (16) die Mischzähne (23, 24) gegeneinander zu bewegen und eine Vermischung der Komponenten (A, B) zu schaffen, und wobei die Zuführung der Komponente (A) und der Komponente (B) vermittels Steuereinrichtungen zur Mischkammer derart erfolgt, dass die Komponente (B) mit einem geringen Vorlauf oder einer Vor-Einspritzung gegenüber der Zuführung der Komponente (A) der Mischkammer zugeführt wird und wobei vor oder bei Beginn des kontinuierlichen Mischprozesses mit der Drehbewegung der gegeneinander laufenden Mischzähne (23, 24) eine Menge von 0,1 Gramm bis 5 Gramm, bevorzugterweise 0,2 Gramm, pastöse oder flüssige Komponente (B) in die Mischkammer eingespritzt bzw. injiziert wird.
