A method of coating threads using a printhead having rows of nozzles extending along a length of the printhead. The method includes the steps of: feeding the thread along a length of the printhead; and ejecting ink from the rows of nozzles towards the thread. Thread-coating modules and thread-coating systems make use of the method described.

An adhesive dispensing system and method are configured to melt adhesive on demand and maintain the adhesive in a liquid state between dispensing cycles. The dispensing system includes a dispensing applicator with a manifold passage, a receiving device including a receiving chamber for holding a small amount of solid adhesive at the dispensing applicator and a first heating device for melting the adhesive on demand, and a second heating device at the manifold to maintain the temperature of the melted adhesive before dispensing. The second heating device applies heat energy to maintain the adhesive in the manifold passage as a liquid.

Disclosed are a substrate treating apparatus and a substrate treating method. According to an embodiment of the inventive concept, the purge operation of the purge nozzle is performed while the nozzle arm is moved from the first substrate support member to the second substrate support member, it hardly influences the operation of treating the substrate while the nozzle arm is moved from the first substrate support member to the second substrate support member. According to an embodiment of the inventive concept, the substrate treating apparatus may perform an operation of purging the photosensitive liquid nozzle while the treatment liquid supply unit performs a process of supplying the photosensitive liquid to the substrate. Accordingly, because the operation of purging the photosensitive liquid nozzle is performed at the same time when the substrate treating apparatus performs a process, productivity may be improved.

A mud pumping apparatus that can be removably coupled to a container the mud was originally provided in when first obtained by the user. The mud may be mastic, mortar, grout, joint compound, spackle, or the like. The apparatus may be sized to be used with various standard sized containers, and adjustably powered and controllable to be used with different types, consistencies, and viscosities of spreadable material.

A pump arrangement, in particular in a coating installation for the coating of components, such as a painting installation for the painting of motor vehicle body components, is provided. The pump arrangement includes a plurality of adjustable pumps for delivering a coating agent, e.g. for delivering a sealing agent for the sealing of weld seams on a motor vehicle body component. The pumps are connected in parallel such that the pumps extract the coating agent for delivery from a common inlet line and deliver said coating agent into a common outlet line. The arrangement further includes a control device for the open-loop or closed-loop control of one fluid variable at the outlet of the individual pumps, respectively, wherein the control device actuates the individual pumps individually, and/or a monitoring unit, which switches the pumps on and off non-simultaneously.

A method and apparatus for applying a sealant to a structure. The method comprises scanning a surface of the structure with a vision system to form scanned data. The method further determines a sealant application path for the structure using the scanned data. The method also controls movement of an application tip along the sealant application path using a controller.

The disclosure relates to a supply system for supplying multiple consumers with a substance to be applied, preferably paint, for application to motor vehicle bodies and/or add-on parts thereof. The supply system comprises a feed line, a return line, a first consumer device which comprises a first consumer, the first consumer being connected to the feed line and the return line and preferably forming a first consumer of the feed line in the flow direction of the substance to be applied, and a further consumer device which comprises a further consumer, the further consumer being connected to the feed line and the return line and preferably forming a last consumer of the feed line in the flow direction of the substance to be applied and/or being arranged after the first consumer in the flow direction of the substance to be applied. The supply system is distinguished in particular in that the feed line is connected to the return line via a connecting line. The disclosure relates further to an associated coating installation and to an associated supply method.

Devices and methods for preparing a slurry for coating onto a substrate. The devices and methods of the present disclosure relate to providing a slurry in a closed volume with at least one passage. The slurry includes a solvent, a powder, and a binder. The slurry can also include a dispersion agent. The slurry is forced repeatedly under high pressure through the at least one passage in a first flow direction and then back through the at least one passage in a second flow direction, opposite the first flow direction. The forcing homogenously disperses the powder and the binder within the solvent. Both sides of the substrate are then coated simultaneously with the slurry extruded from the closed volume after the forcing. Curing of the coated slurry includes freeze drying to preserve the porosity of the slurry on the substrate.
