Abstract
An apparatus for measuring the length of curved segments including loading pairs of rollers with one roller of each pair being driven, positioning switches, positioning shaped reciprocally movable elements defining a hollow to house the segment to be measured and movable arms and feelers to measure the segment. The hollow has a shape corresponding to the theoretical shape of the segment. The movable elements are fitted with openings for at least one of the ends of the segment. The feelers are arranged in correspondence with the openings to cooperate with the relevant ends of the segment.
Claims11
An apparatus for measuring the length of curved segments, comprising:
- a frame;
- positioning means, carried by the frame, including:
- two shaped elements adapted to define a housing for the segment to be measured, said housing having a shape corresponding to the theoretical shape of the segment and defining two openings for the passage of the ends of the segment;
- and means for successively displacing said shaped elements from a position for receiving a segment to a measuring position and back to said receiving position for removal of the measured segment;
- measuring means, carried by the frame, including two movable arms with contact feelers for contacting, respectively, the ends of the segment projecting through said openings in said measuring position, located intermediate said arms;
- means for biasing the feelers towards the ends of the segment and transducer means for providing a signal responsive to the mutual distance of the feelers.
