Elastomeric-coated roll and method and apparatus for making the same.

摘要

The invention contemplates a thin and uniformly applied elastomeric coating for a cylindrical roll, in mass-produced volume. A succession of like vertically oriented cylindrical rolls (12) is conveyed along an endless path of movement (10) which includes a segment (A) that is cylindrically arcuate about a vertical axis of electrostatic spray-disc rotation. A solvent mixture of elastomeric-ingredient material is continuously applied to the rotating disc (B) while the latter is vertically oscillated over the length of the rolls (12) and while the rolls (12) in the segment (A) are continuously rotated about their individual axes. The path of movement includes a course which leaves the segment and later rejoins the segment, after passage through a zone of partial curing, the cycle being repeated for multiple-pass building to desired coating thickness.
