Abstract
A plastic resin pelletizer system for controlling the position of the pellet cutting knife blades in relation to a die plate face includes vibration detection pick-up in the form of a piezoelectric accelerometer mounted to the pelletizer die plate. Characteristic frequencies or a signature output is identified as representing the condition of contact between the blades and the die face, and the amplitude of the characteristic signature is used to indicate the extent or degree of pressure of the contact, in controlling the position of the knives with respect to the die plate.
