Abstract: A shaft collar and shaft coupling assemblies adapted for use in the food-processing and similar industries. The assemblies include a shaft collar or shaft coupling disposed within an associated multi-element shroud. The shroud provides a cover overlying the collar or coupling, eliminating exposed features that can trap food particles, thereby effecting a high level of cleanliness of food-processing equipment upon which the collar or coupling is secured, while retaining many of the advantages of a conventional collar or coupling.

Abstract: A method is disclosed for scraping a roll surface rotating in a molten metal coating process comprising traversing a support assembly to one side, lifting the arms attached to said the assembly to a fully retracted position to disengage scraper blades from contact with a roll surface; initiating a scrape cycle by means of a trigger signal; lowering the arms and scraper blades in the mid-point of the sink roll; increasing the pressure reference from lifting pressure to approximately zero; energizing one or more directional valves; increasing the pressure value gradually to a preselected pressure; extending the cylinder in a controlled manner to engage the scraper head gently on to the sink roll; moving the engaged scraping head at controlled, predetermined speed from the sink roll mid point to the fully traversed out position; stopping the traversing means upon reaching the fully traversed out portion; and lifting the scraper head from the roll surface by removing pressure from the cylinder; then repeating the

Abstract: An apparatus for scraping the surface of a sink roll in a molten metal coating process comprises a support member having a pair of linearly movable arms supported thereon. The support member depends from a bridge structure spanning a continuous metal coating line, and a pair or arms, the arms being disposed on opposite sides of said support member. Each arm has a scraper assembly portion attached thereto. Each scraper assembly portion has two blades affixed thereto, a forward scraper blade and a rear scraper blade, with a connecting portion connecting the two blades. The connecting portion also has a first pivot point for attaching the connecting portion to the arm associated with the scraper assembly portion, the first pivot point being disposed between said forward and rear scraper blades for following the radial contours of the roll surface. A second pivot point permits the blades to follow the crown of the roll.
