Orienting and feeding apparatus and method for manufacturing line
Apparatus and methods for rapidly orienting and feeding generally cylindrical, elongated objects having a maximum transverse diameter Y. First and second conveying belts are provided having input and output ends for cooperatively conveying such objects toward a downstream processing line. The belts are mounted so that their respective conveying surfaces are movable in a common parallel direction. The facing edges of the conveying surfaces of these belts are spaced from one another to define a uniform gap between them of a dimension less than Y. The conveying surfaces are upwardly sloped away from the gap, to define a zone converging downwardly in the direction of the gap. Object input means deposit the initially unoriented elongated objects at the input ends of the conveying belts. The belts are moved in a common direction, but at different speeds. The elongated objects are rotated by contact with the differentially speeding belts as they descend into the converging zone and become supported at the gap and conveyed by riding on the edges of the moving belts which border the gap. The objects as they descend become oriented in positions of gravitationally maximum stability relative to the mode of support, these positions being characteristic for the objects. Object output means at the ends of the belts receive the oriented objects and direct them toward the downstream processing line.

A cutting head is provided for milling rumble strip depressions in a road surface. The cutting head has a center rotational axis and a transverse diameter that varies along the length of the rotational axis so that an outer cutting surface of the cutting head defines a plane curve, such as an ellipsoid with truncated ends. The cutting head is mounted on a milling machine and rotated about the rotational axis as it is moved alternately up and down into the road surface. As the milling machine moves down the road, the movement of the cutting head creates spaced apart rumble strip depressions in the road. Because of the elliptical configuration of the cutting head cutting surface, the dimensions of the depressions can be varied along both the forward and lateral axes by simply varying the depth of cut. The curved profile of the cutting head along the rotational axis creates rumble strip depressions that avoid the sharp ninety degree corners and vertical side walls found in conventional rumble strips.
