Seam Detectors

Accurate, Reliable Seam Detection for Automated Web‑Handling Processes

The Menzel Seam Detector is engineered to precisely locate seams and trigger automated machine functions with exceptional accuracy. Available in both mechanical and electronic configurations, these systems integrate seamlessly into finishing, winding, and processing lines—ensuring consistent performance across a wide range of materials, colors, and opacities.

Whether used to protect sensitive equipment, activate downstream operations, or improve process timing, Menzel seam detectors deliver dependable, user‑friendly control for modern web‑handling environments.

Menzel seam detectors can be integrated to trigger a wide range of automated machine responses, including:

  • Opening a calender nip for seam passage
  • Raising a shearing blade
  • Activating a seam‑mapping system
  • Triggering an alarm or warning light
  • Raising sueding machine sanding rolls
  • Stopping the machine at the exact seam position

Mechanical Seam Detector

Menzel’s mechanical seam detector uses non‑marking sensing rolls and a precision gap‑adjustment mechanism to detect seams across a variety of fabric thicknesses. Its rugged steel construction ensures long‑term reliability in demanding production settings.

Standard Features

  • Sturdy steel framework for years of dependable service
  • Two non‑marking sensing rolls for accurate seam detection
  • Micrometer gap adjustment to accommodate different fabric thicknesses
  • Limit switch for activating preset machine functions

Electronic Seam Detector

The electronic seam detector uses dual photo‑electric sensors housed in a deep‑throat sensing head to deliver the highest level of detection accuracy—regardless of fabric color, opacity, or consistency. Minimal adjustment is required when switching between materials.

Standard Features

  • Deep‑throat sensing head with dual photo‑electric sensors
  • Operator control box with sensitivity adjustment
  • On/off switch and output relay for seamless integration
  • Highly accurate detection with little or no reconfiguration

Optional Features

  • Electronic timer for enhanced seam‑location accuracy
  • Second contact with adjustable delay for multi‑stage activation
  • Preset counter for triggering functions at predetermined yardages
