Surface treatment of a tubular surface defining an axis extending from a first surface end to a second surface end includes partially surrounding the tubular surface, at a first position, with a first set of treating units, with the treating units arranged in a first arcuate array. Furthermore, each treating unit is configured to include a plurality of first applicator heads. In some examples, a position of each of the plurality of first applicator heads is determined relative to the tubular surface. The first set of treating units is moved from the first position towards a second position. In one non-limiting example, each of the plurality of first applicator heads is independently controlled to selectively apply a first treatment as the first set of treating units moves from the first position towards the second position.

Provided is an apparatus for coating a girth weld and a cutback region surrounding said girth weld, said apparatus having lateral travel at least equal to the length of the cutback region and circumferential rotational travel around the pipe. The apparatus can provide a multiple component coating accurately and safely, without the need for solvent flushing of the apparatus.

A fixture, system, and method for coating a glove with a coating material are described. A fixture includes a support member and a clamping member movable relative to the support member to a closed position. The clamping member is configured to be at least partially received in a cuff of the glove. In the closed position, the cuff is captured between the clamping member and the support member. In this configuration, a majority of an external surface of the glove is exposed for being coated. A glove-coating system can include one or more fixtures on a conveyor that move the fixture around various processing stages of the glove-coating system. In certain methods of coating a glove, coating material is applied to the glove while the glove is suspended from the fixture. The coated glove can be removed from the fixture without being everted.

In a flow down type surface treating apparatus, a scattering amount of a processing solution Q is reduced. A honeycomb member 60 is provided vertically below a transport hanger 16. The honeycomb member 60 consists of a plurality of tubular members with hexagonal holes connected together. When the processing solution Q falls in a vertical direction (in the direction of an arrow α), the processing solution Q passes through through-holes of the honeycomb member 60. When the processing solution Q hits liquid level H, a part of it is reflected. Since a part of the reflected processing solution Q is reflected obliquely, it collides with an inner wall of the through-hole of the honeycomb member 60. As a result, the amount of the treatment liquid Q that emerges again on an upper surface of the through-holes is reduced. Thereby, the honeycomb member 60 exhibits a scattering prevention function.

Coating apparatus (20) includes a pair of juxtaposed bodies (22, 24, 112, 114, 112a, 114a, 138, 140) defining a nip region (30, 126, 126a, 150) therebetween, with each presenting a periphery (26, 28, 116, 118, 116a, 118a, 144, 146) and being rotatable in opposite directions, respectively. The peripheries (26, 28, 116, 118, 116a, 118a, 144, 146) of the bodies (22, 24, 112, 114, 112a, 114a, 138, 140) are provided with a series of indentations (32, 120, 120a, 148). Liquid coating material is directed onto the bodies (22, 24, 112, 114, 112a, 114a, 138, 140) through an outlet (100, 110, 158) during rotation of the bodies (22, 24, 112, 114, 112a, 114a, 138, 140). This generates an adjustable spray or fog flow pattern (108) for effective coating of a substrate.

Coating apparatus (20) includes a pair of juxtaposed, cylindrical bodies (22, 24) defining a nip region (30) therebetween, with each presenting a periphery (26, 28) and being rotatable in opposite directions, respectively. The peripheries (26, 28) of the bodies (22, 24) are provided with a series of laterally extending notches (32), optionally oriented to provide chevron patterns (68) with apices (32a) and diverging legs (70a, 70b); the patterns (68) are positioned so that the apices (32a) first pass through the nip region (30), with the legs (70a, 70b) in trailing relationship. Liquid coating material is directed onto the bodies (22, 24) through an outlet (100, 110) during rotation of the bodies (22, 24). This generates an adjustable spray or fog flow pattern (108) from the apparatus (20) for effective coating of a substrate.

The present invention provides a dispensing adjustment system, which includes an optical measuring unit, a calculating unit and a glue dispensing control unit. The optical measuring unit measures a glue to obtain a N.sup.th 3D glue signal or a N.sup.th 2D glue signal. The calculating unit receives the N.sup.th 3D glue signal or the N.sup.th 2D glue signal to obtain the volume or the weight of the glue, and compares the volume or the weight of the glue with a default glue value. If the volume or the weight of the glue fails to conform to the default glue value, the calculating unit transmits a N.sup.th glue dispensing adjustment signal to a glue dispensing control unit for the glue dispensing control unit to adjust the glue supplied thereby according to the N.sup.th glue dispensing adjustment signal. The invention can solve the problem that the glue is insufficient or overflows in order to improve the bonding quality.

The disclosure relates to a method and apparatus for preventing oxidation or contamination during a circuit printing operation. The circuit printing operation can be directed to OLED-type printing. In an exemplary embodiment, the printing process is conducted at a load-locked printer housing having one or more of chambers. Each chamber is partitioned from the other chambers by physical gates or fluidic curtains. A controller coordinates transportation of a substrate through the system and purges the system by timely opening appropriate gates. The controller may also control the printing operation by energizing the print-head at a time when the substrate is positioned substantially thereunder.

A substrate treating apparatus includes a plurality of solution treating units for performing solution treatment of substrates, and a plurality of individual gas supply devices provided to correspond individually to the solution treating units, each for supplying gas at a variable rate only to one of the solution treating units. The solution treating units perform the solution treatment by supplying treating solutions to the substrates. The individual gas supply devices supply gas only to the solution treating units corresponding thereto. The individual gas supply devices supply the gas at adjustable rates to the solution treating units. The rate of gas supply to the solution treating units can therefore be varied for each solution treating unit.
