A load lock chamber and method for transferring large area substrates is provided. In one embodiment, a load lock chamber suitable for transferring large area substrates includes a plurality of vertically stacked single substrate transfer chambers. The configuration of vertically stacked single substrate transfer chambers contributes to reduced size and greater throughput as compared to conventional state of the art, dual slot dual substrate designs. Moreover, the increased throughput has been realized at reduced pumping and venting rates, which corresponds to reduced probability of substrate contamination due to particulates and condensation.

A cold rolling process for impressing a pattern on a surface of a sheet metal article involves passing the sheet article through a pair of rolls and engaging a patterning feature with isolated areas of a surface of the sheet article, at a localized pressure to plastically deform at least the surface of the sheet article. A rolling pressure is maintained on other areas of the sheet article that is less than the bulk elastic yield strength of the metal. A cold rolling apparatus is also described having a pair of rolls, each with partially cylindrical outer surfaces. The rolls have a gap between the cylindrical parts. One of the rolls has a localized surface region that is displaced relative to the surface of the roll. When the localized region is brought near the other roll, a spacing exists that is narrower than the gap. One of the rolls has a localized patterning feature that aligns with the localized surface region to impress a pattern into the sheet article. The gap allows the rolls to engage opposite surfaces of the sheet article while imparting compression less than a bulk elastic yield strength of the metal.

Disclosed is a roll for embossing aluminum sheet, which is obtainable by subjecting a surface of a steel roll to at least the steps of, in order: blasting treatment, electrolytic treatment with 1,000 to 20,000 C/dm² of electricity in which the steel roll is used as the anode, and chromium plating treatment. The aluminum sheet embossing roll of the present invention has on the surface thereof peaks, or asperities, which are of uniform height and very numerous. As a result, aluminum sheets obtained using such a roll, when employed as lithographic printing plate supports, have excellent printing characteristics, particularly a long press life and a high sensitivity.

A turnover apparatus and method for inverting articles such as lumber or board pieces being conveyed sideways on two or more conveyor chain loops in which each article is advanced on the conveyor chain loops by speed up belts engaging the underside of the articles to force a leading side against a pair of lugs mounted on a respective conveyor chain loop, the article thereafter flipped up to an on edge position by flipper arms also mounted on the conveyor chain loops which each engage an adjustable cam ramp at a turnover station, the article thereafter tipped over backward by being driven by the speed belts against an elevated overhung trailing edge on the lugs to complete the turnover. Optional pivoted let down elements may be arranged to engage the trailing side of the articles to controllably lower the same by motion induced by a second cam ramp at the turnover station.

An electric wire sizing-cutting apparatus including an electric wire delivery apparatus, which is easily handled and can smoothly supply the electric wire without generating a kink, is provided. The electric wire delivery apparatus includes: a transfer means transferring an electric wire, which is delivered from an electric wire reel, along a longitudinal direction of the electric wire; a correcting means arranged between the electric wire reel and the transfer means and correcting a bending habit of the electric wire by allowing the electric wire to pass through between a plurality of rollers arranged zigzag; and a rotation controlling means arranged on an upstream-side of the correcting means and putting the electric wire between a pair of rollers biased in a direction approaching each other.

The invention relates to a method and device for the inspection of a rolled strip, wherein a strip sample (M) is inspected on a first surface thereof and then turned over in order to inspect the second surface thereof. According to the invention, by displacement parallel to the longitudinal axis thereof, the strip sample (M) is placed is placed between two spaced squeezing devices (6, 6') (7, 7') which are respectively tightened on each transversal extremity (M1, M2) of the sample (M); the two squeezing devices (6, 6') (7, 7') are longitudinally separated from each other in order to place the sample in a state of tension for the visual inspection of a first surface, then the sample is turned over by simultaneous rotation of the two squeezing devices (6, 6') (7, 7') about the longitudinal axis O, with maintenance of the applied tension, in order to carry out inspection of the second surface, said tension being sufficient in order to carry out inspection without the need for placement on a table. The invention makes it possible to inspect a strip as it exits from a continuous rolling line.

Other embodiment include shaping by contouring length of the vessel, applying decoration to the vessel, wherein the decoration is added at a precise location based in part on reference to the registration spot, and using a controller to select the pathway based in part on desired shape of the vessel.

A product handling system comprises a support structure defining a pair of stationary inverted first channels with downwardly facing open sides. At least one cylindrical drum is interposed between each of the first channels and an underlying receiver. The drums are rotatable about their axes, with their surfaces arranged to close the open sides of the respective first channels. The drum surfaces are interrupted by second channels, with the first and second channels and the drum axes being arranged in a parallel relationship. Successive product lengths are alternately delivered longitudinally into one and then the other of the first channels. The drums are rotated about their axes resulting in the thus delivered product lengths being sequentially: (i) temporarily retained in the first channels by the rotating drum surfaces; (ii) deposited from the first channels into the second channels when the second channels rotate into radial alignment and communication with the first channels and (iii) downwardly deposited from the second channels to the receiver when the second channels rotate to discharge positions over the underlying receiver.
