ABSTRACT:
A device for planishing a band saw blades or the like, includes elements for continuously driving the blade, elements for detecting deformations of the blade and planishing elements. The detecting elements consist of position sensors integral with a table positioned underneath the blade, the sensors being uniformly spaced on a line transverse to the forward moving direction of the blade, and the planishing elements consist of hammers co-operating with an anvil positioned underneath the blade, such that, when a sensor detects a deformation of the surface of the blade body, the hammer corresponding to the sensor is actuated to even out the deformation.
