Abstract
Apparatus for machining the surface of an elongated rigid workpiece passing therethrough in a predetermined direction along a path. The apparatus includes at least one station having opposed tools for engaging opposite sides of the workpiece. The tools have tool axes extending generally perpendicular to the path. The tools are mounted for movement of their axes toward and away from the path, and for tilting movement of their axes relative to the path in a plane extending generally perpendicular to the path.
Claims18
Apparatus for working on the surface of an elongated generally flat rigid workpiece passing therethrough in a predetermined direction along a path comprising;
- at least one station having opposed generally cylindrical tools for engaging opposite generally flat irregular sides of a workpiece, said tools having tool axes extending generally perpendicular to said path, mounting means mounting said tools for automatic movement of said axes thereof toward and away from said path and for automatic tilting movement of said axes relative to said path with said tilting movement being generally in a plane extending generally perpendicular to said path, and said mounting means including yieldable biasing means yieldably biasing said tools toward said path, whereby said tools automatically follow the sides of the workpiece even though such sides are irregular due to curves, twists, and dimensional and shape variations in the workpiece.
Apparatus for machining the surface of elongated longitudinally curved rigid workpieces having opposite generally flat irregular surfaces and nonuniform cross-sectional sizes and shapes along their length comprising;
- a plurality of spaced-apart stations through which the workpieces travel generally longitudinally in a predetermined direction along a path, said stations including opposite end feed stations and at least one intermediate machining station, each said station including opposed generally cylindrical tools for engaging the opposite sides of the workpieces, said tools being rotatable and having tool axes extending generally perpendicular to said path, at least one said tool at each said station being rotatably driven, mounting means mounting said tools for automatic movement of said tool axes toward and away from said path and for tilting movement of said axes relative to said path with said tilting movement being generally in a plane extending generally perpendicular to said path so that said tools automatically move to follow curvatures and irregularities in the workpieces, and yieldable biasing means yieldably biasing said tools toward said path.
