Automatic Paper Cutting Machine Using Geneva Mechanism Project

Mechanical & Theory of Machines fabrication final year project with complete documentation support.

The Geneva mechanism converts continuous rotary motion into intermittent indexing motion — ideal for feed-and-cut cycles. In a paper cutting machine it advances the paper by a fixed length, pauses for the cut, then repeats, giving consistent strip or sheet lengths without complex electronics.

This project fabricates an automatic paper cutting machine driven by a Geneva wheel, motor, cutting blade and feed rollers. The design covers Geneva drive geometry, frame fabrication, blade actuation and paper handling — ideal for Mechanical Engineering students studying intermittent motion and machine design.

Abstract

Many packaging and stationery processes need paper or sheet material cut to a fixed length in a repeating cycle. A Geneva mechanism provides a simple, purely mechanical way to obtain intermittent feed: the driving pin engages the Geneva wheel for a fraction of each revolution, indexes the feed, then dwells while the blade cuts.

This project develops an Automatic Paper Cutting Machine Using Geneva Mechanism with a motor-driven Geneva drive, feed rollers, cutting blade and support frame. Key subsystems include Geneva wheel and driver design, power transmission, blade actuation and paper path. The unit demonstrates intermittent motion, machine kinematics and practical fabrication suitable for academic evaluation.

It is an excellent final-year project for Mechanical and Production Engineering students, combining Theory of Machines concepts with a working fabrication model.

Working Principle

  • Motor rotates the Geneva driver continuously; the pin engages the Geneva wheel slots for intermittent indexing.
  • During the index phase, feed rollers advance the paper by a fixed length.
  • During the dwell phase, the cutting blade descends (cam or linkage actuated) to cut the paper.
  • Cycle repeats: feed → stop → cut → feed, producing uniform cut lengths.

Advantages

  • Purely mechanical intermittent motion — no complex electronics required.
  • Consistent cut length determined by Geneva indexing and roller geometry.
  • Clear demonstration of Geneva drive kinematics and dwell periods.
  • Suitable for academic study of Theory of Machines and machine design.

Challenges

  • Accurate Geneva wheel and pin geometry for smooth engagement.
  • Synchronising blade stroke with the dwell interval.
  • Minimising paper slip in feed rollers for length accuracy.
  • Frame rigidity and blade sharpness for clean cuts.
