A cut-to-length line for processing coiled sheet metal having a thickness of greater than 0.200 inches has an uncoiler, a descaler, and flattening machinery which may be a stretcher leveler or a temper mill. The line is operated in an advancement mode by (i) the advancing the sheet metal through the line; and (ii) descaling the sheet metal in the descaler. In one aspect, when a length of sheet metal to be stretch leveled is positioned in the stretcher leveler, the line may be operated in an idle mode by: (i) stopping the advancement of the sheet metal from the uncoiler through the descaler; (ii) stopping descaling of the sheet metal in the descaler; and (iii) stretch leveling the length of the sheet metal. When stretch leveling is complete, the line may be operated in the advancement mode.

First guide pipes are disposed on both sides of blasting areas, and second guide pipes are disposed on both sides of the blasting area. A wire rod W is inserted through the first guide pipes and the second guide pipes, penetrating in a conveying direction of the wire rod W. The diameter of each of first insertion holes of the first guide pipes and second insertion holes of the second guide pipes is gradually reduced toward the downstream side in the conveying direction. The second guide pipe is installed in a state in which the downstream-side end portion in the conveying direction is inserted into the first insertion hole from the inlet side of the first guide pipe.

A rotary wheel cleaning device comprises a feeding station, a cleaning station, a blowing station and a discharging station. The feeding station completes positioning, jacking and clamping of a wheel; the cleaning station completes cleaning of the wheel; the blowing station completes blowing of the wheel; and the discharging station transfers the cleaned wheel. The device can be used for automatic continuous production, in which the wheel can horizontally rotate and turn over during cleaning, so that the wheel is cleaned in multiple angles and multiple directions; and by skillful layout, feeding, cleaning, blowing and discharging of the wheel are orderly engaged, so that the cleaning process is coherent and cyclic, the period is short and the efficiency is high.

A turnover mechanism is configured to receive and flip over parts delivered by an in-feed conveyor to an out-feed conveyor. The turnover mechanism includes a frame and a gripper assembly coupled to the frame. The gripper assembly is configured to secure and move a part having one surface treated from the in-feed conveyor. The turnover mechanism further includes a flipper assembly coupled to the frame, the flipper assembly being configured to rotate and deliver the part to the out-feed conveyor with an opposite surface of the part exposed for treatment.

A shot-blasting machine for the treatment of metal pieces and the related shot-blasting system. In particular, a shot blasting machine provided with special support devices to improve the operation of its conveyor belt, so as to overcome technical drawbacks that are rather common in conventional shot blasting machines having a metallic conveyor belt.

Cutting method of a layer(S) of ceramic powder material having a modulus of rupture that is smaller than about 10 N/mm.sup.2, comprising: a step of moving the layer(S) of ceramic powder material along a given path (P) in a moving direction (A) through a cutting station; and a cutting step, during which at least a first water-jet cutting device cuts said layer(S) of ceramic powder material along a first direction (D1) that is transverse to the moving direction (A), so as to cut said layer(S) of ceramic powder material and obtain a plurality of articles of ceramic powder material (MCP).

The present invention relates to a method of producing gelatine, the method comprising the steps of: providing animal material containing collagen; cutting the animal material with at least one fluid cutting jet to form animal material sections; hydrolysing the collagen in the animal material sections to form gelatine; and isolating the gelatine. The invention also relates to a fluid jet cutting device and to the use of a fluid jet cutting device in the production of gelatine. The invention is particularly useful in the production of gelatine from pig skin and/or cow hides and/or fish skin.

Systems and methods treat sucker rods in a machine through a multi-step process. Initially, sucker rods are cleaned before being conditioned. The conditioning process involves using a defined type and a defined size of media, applied at a first intensity to the rods using first media accelerators (first wheels with a specific diameter and rotational speed, and/or imparting a certain amount of media). The conditioned surfaces are then shot peened at a higher intensity using second media accelerators, which can have larger diameters, faster rotational speeds, and/or can impart a greater amount of media. Both the conditioning and shot peening processes involve reclaiming the media for reuse.
