ABSTRACT:
An ultrasonic testing apparatus which is mounted on the housing of a trimming device for one marginal portion of a sheet- or band-like workpiece moving lengthwise along a horizontal path. The testing apparatus has a deflector which is pivotably mounted on the housing by a hinge so that it can turn about a vertical axis and has ways for a pneumatic cylinder and piston assembly whose piston rod carries a roller follower movable at right angles to the path toward and away from engagement with one side of that marginal portion of a workpiece in the horizontal path which is about to be trimmed by the trimming device. The probe holder with the probe of the testing apparatus is mounted on a parallel motion mechanism which is carried by the piston rod and is biased by a spring so as to maintain the probe close to the one side of the one marginal portion of a moving workpiece when the latter is engaged by the roller follower. A spring automatically retracts the piston rod from the path in the event of malfunction of the cylinder and piston assembly, and the parallel motion mechanism carries a nozzle which discharges streams of compressed air serving to blow a liquid couplant off the one side of the workpiece downstream of the probe.
