INTRODUCTION

The AgrTopWave LLC Hot Wire Cutter (HWC) has been designed for section weight analysis

of PET containers In section weight analysis the PET container is cut to a predefined number of sections at predefined cutting locations, and the weights of the sections are monitored over time The weight of each section represents the average sidewall thickness of the corresponding sidewall area

Flexibility of the design enables a quick change from one bottle design to another, and easy adjustment of the cutting locations according to the size and shape of the container To ensure maximum efficiency, we recommended that each bottle production line have its own dedicated Hot Wire Cutter and electrical balance

This document contains the necessary unpacking, set-up instructions, and description of the cutting procedures

SCOPE
