A fluid delivery device is provided. The fluid delivery device includes a melter having a loading chamber and a hopper disposed in communication with the loading chamber, the loading chamber having one or more heating elements. The hopper includes a second heating element. The melter also includes a container handling system for lifting a container a predetermined height and moving the container from a position remote of the melter to a position within the loading chamber. The container includes contents stored within. The heating elements heat the contents so that the contents may be received in the hopper. The hopper may continue to heat the contents to provide a fluid. The fluid may be discharged from the hopper by way of a pump assembly. A pressure of fluid may be regulated at the pump assembly.

The invention relates to a dosing system (1) for a dosing material having a dosing device (5) with a housing (11), the housing (11) comprising a feed channel (80) for dosing material, a nozzle (40), a discharge element (31) and an actuator unit (10) coupled to the discharge element (31) and/or the nozzle (40). The dosing device (5) further comprises a dosing material reservoir (70) which is coupled to the housing (11) or integrated into the housing (11). The dosing system (1) has a plurality of temperature control devices (2, 2′, 2″) which are each assigned to different temperature zones (6, 6′, 6″) of the dosing system (1) in order to control the temperature zones (6, 6′, 6″) differently. At least one first temperature zone (6) is assigned to the dosing material reservoir (70) and at least one second temperature zone (6″) is assigned to the nozzle (40). Preferably, at least one of the temperature control devices (2, 2′, 2″), preferably at least the temperature control device (2) assigned to the dosing material reservoir (6), comprises a cooling device (3, 3′, 3″) having a cold source (93, 93′, 95, 99).

A melter for preparing a molten medium, in particular for preparing a molten adhesive, has a melting tank that has a melting chamber for receiving and melting a medium to be melted. The melter has a heating device for heating the melting chamber. The melting chamber has an upper chamber section and a lower chamber section. The melting tank has a dispensing opening that can be fluidly connected to a delivery device for delivering the molten medium. The melting tank further has a drain opening. The dispensing opening and the drain opening open into the lower chamber section. The melter further has a closure body for closing the drain opening. In a closed position, the closure body closes the drain opening and an end section of the closure body projects into the lower chamber section.

A modular fluid application device (10) includes a module base (12) and first and second fluid passageways extending within the module base and intersecting to form a nozzle fluid supply passageway. The modular fluid application device also includes a fluid outlet (22) formed on a nozzle mounting surface (24) of the module base fluidically connected to the nozzle fluid supply passageway, a base air passageway extending in the module base and an air outlet formed on the nozzle mounting surface fluidically connected to the base air passageway. A first module bank (14) is removably mounted on the module base and includes at least one first module having a first valve configured to control a flow of fluid in the first fluid passageway. A second module bank (18) is removably mounted on the module base and includes at least one second module having a second valve configured to control a flow of fluid in the second fluid passageway. The first module and the second module are mounted at an angle relative to one another.

The invention relates to a method for operating a machine, in particular a coating machine, preferably a narrow-edge coating machine, such as those used e.g. in the furniture or component industry. The method comprises the following steps: transferring a plurality of input values from a storage device to a control device of the machine, the input values relating to at least one material and/or tool used in a processing of a workpiece, preparing the machine for processing based on the input values, processing a workpiece with the prepared machine, changing the input values based on the processing and/or the product, and transferring the changed input values to the storage device.

A system of treating installed railroad ties, comprising a conveyance vehicle configured to move along a railroad track, one or more drill carriages slidably attached to the conveyance vehicle to drill one or more holes at predetermined locations in the railroad ties, an air dispenser configured to deliver a blast of air proximate the one or more holes sufficient to remove debris from and around the one or more holes, a preservative dispenser configured to deliver a predetermined amount of preservative material into the one or more holes, and a plug dispenser configured to deliver a plugging material to the one or more holes to seal the preservative material in the one or more holes.

A distribution system for storing and conveying a supply of material is described. The distribution system includes a bin for storing and conveying a supply of material. The bin includes a housing defining an internal chamber configured to receive the material, at least one outlet configured to direct the material from the bin, a plate defining a lower end of the internal chamber and supporting and directing the material to the at least one outlet, an agitation device attached to the plate, and a gasket disposed between the plate and the housing.

A method for controlling a recirculation pump assembly is disclosed. The method includes receiving a process-dependent characteristic and determining a recirculation flow rate of adhesive that flows to the recirculation pump assembly based on the process-dependent characteristic. The method further includes determining a recirculation pump speed of the recirculation pump assembly for pumping the adhesive to a supply channel using the recirculation flow rate, and adjusting an operating speed of the recirculation pump assembly to match the recirculation pump speed. A system and storage device for performing the above method are also disclosed.

In one example, a method of fabricating a product, such as a diaper, includes a step of folding a substrate of the product to form a plurality of pleats in the substrate. The method includes a step of applying a liquified elastic to the substrate such that the liquified elastic adheres to the substrate and extends across the plurality of pleats. The method includes a step of allowing the liquified elastic to solidify on the substrate.
