Three Belt System
The DLWPRO and DLWPROM series of automatic checkweighing machines all use a three belt system to transport products along the conveyor, each belt performs a specific role in ensuring each product is weighed with high accuracy and any out of tolerance products are rejected.

  • Infeed Belt Conveyor – Required to increase or decrease the speed of the prepackaged product before it reaches the weigh belt.
  • Weigh Belt Conveyor – Typically mounted above a high precision load cell used to dynamically weigh each product at high speed.
  • Rejection Belt Conveyor – Products that are out of permitted tolerances are rejected using either an air jet or pneumatic pusher rejection system
