A spray gun cover is made of flashspun high-density polyethylene fibers (e.g., Tyvek), another cloth-like material, plastic, or fabric. The cover is self-sustaining, and an elastic material is disposed at openings of the cover to secure the cover at the nozzle around the nozzle opening of the spray gun cover and at the back of the spray gun around a large opening of the spray gun cover. Through the cover, the paint cup or reservoir and the spray gun are covered and protected from airborne fluid or dry particles that bounce back from the surface of the item being sprayed with paint, stain, or other fluid (overspray). Additionally, an air hose cover is also made of flashspun high-density polyethylene fibers or the like and covers and protects an air hose for a spray gun.

A service tracking system for a printing press (1), spray applicator (1′) or the like includes at least one replaceable component (10) having at least one memory unit (20). The service tracking system further includes a controller (30) which is connected to the memory unit (20). The controller (30) is configured to control the operation of the replaceable component (10) and to periodically update data stored on the memory unit (20) related to run-time data regarding the operation of the specific replaceable component (10).

A fluid dispenser apparatus includes a fluid dispenser having plurality of nozzles aligned in a first longitudinal direction. A dispenser shield is positioned relative to the plurality of nozzles, the dispenser shield configured to form an aperture aligned in the first longitudinal direction with the plurality of nozzles. The plurality of nozzles are configured to dispense fluid towards a substrate. The dispenser shield is further positioned such that fluid dispensed from a first subset of the plurality of nozzles passes through the aperture while fluid dispensed from a second subset of the plurality nozzles is captured by the dispenser shield.

The present invention discloses a two-dimensional code protective paint spraying equipment for a wheel hub, including a centering device, a paint spraying device, and a review device, which covers a paint film with a certain hardness and transparency on a QR code of a hub, effectively avoiding damage to the QR code by the hub during the loading process, ensuring full flow traceability of the hub.

The present disclosure relates to the manufacture and use of an additive manufacturing (AM) system that employs a spacer flow guide disposed or formed within a housing that defines a chamber of the AM system. The spacer flow guide may direct various portions of a gas flow within the chamber to respective exhaust channels. For example, in combination with portions of the housing, the spacer flow guide may define a main exhaust channel that extends between the chamber and a gas outlet formed in a downstream end of the housing. Additionally, a bypass exhaust channel may be defined between the chamber and a back surface of the spacer flow guide to fluidly couple an upper portion of the chamber to the main exhaust channel.

An aerosol creation system includes a pair of counter-rotating rollers, a nip between the two rollers, the nip having an upstream side and a downstream side, and a pool of fluid on the upstream side of the nip, the fluid being drawn into the nip through the motion of the rollers, such that on the downstream side the fluid stretches between diverging surfaces of the two rollers and forms filaments that breaks up into droplets. A multi-roller aerosol creation system includes more than two rollers arranged to touch each other in a configuration, wherein areas where the rollers touch form nips, each nip having an upstream side and a downstream side, wherein the downstream side of the nips are positioned within a central space within the configuration of the rollers, and fluid surrounding the circular configuration, wherein an outer region of the circular configuration forms the upstream side of the nips.

A venting device with a splash guard for deflection of splashing water entering the interior of the venting device has slats with a front section arranged at the exterior. Venting slots are formed between the front sections. At least one of the slats has a deflection section arranged at the interior and a central section connecting deflection section and front section. The front section and the deflection section are angled relative to the central section. The front section of the at least one slat in the operating position of the venting device extends from the central section toward the top side. The deflection section extends in the operating position from the central section toward the bottom side. The deflection section has a region oriented at an angle of less than 90° relative to the central section. A power tool with such a venting device is provided.

A flexible sheet collects overspray and keeps spray booth environments clean, thereby reducing or eliminating dust and foreign matter from landing on wet painted surfaces which might otherwise result in a paint surface defect. The flexible sheet comprises a woven or non-woven mesh or net material having apertures or perforations that penetrate through the sheet. The sheet is impregnated with a tacky substance, such that paint overspray and dirt particles cling to the impregnated sheet. In the preferred embodiment, the tacky substance is a wax-based substance, more preferably a natural or synthetic beeswax-based substance. The material may be made from polymeric filaments of nylon or other natural or synthetic fibers, threads or strands. The flexible sheet of material may be provided in roll form for use. Method of making a tacky netting are also disclosed. The product is particularly useful in vehicle spray-booth applications.
