Abstract

A continuous plate or track is supported on a table. The plate is fed past a series of micro-punches which reciprocate and form the required profile, being actuated by a hydraulic powered device. The application is typically to mixtures of asbestos fibres and cement. The frequency of the vibrations varies between 1000 and 10,000 per minute, depending on the density and the thickness of the material. The translation speed of the material being worked relative to the micro-punches varies between 0.1 and 3 metres per minute, as a function of the nature, density and thickness of the material.
