Mesh Angle Bead Roll Forming Machine | Corner Bead & Stop Bead Production Line – PUTAI - Tianjin, China

PUTAI Mesh Angle Bead Roll Forming Machine – Automatic Corner Bead and Stop Bead Production Line

The PUTAI mesh angle bead roll forming machine is an automatic production line that forms metal coil into angle beads with mesh or perforated wings, used to protect and finish external corners in plaster, render, stucco and drywall systems. Galvanized steel strip runs through 15 forming stations and a servo tracking cutter, producing finished corner beads to length in one continuous process. Quick-change tooling lets one line produce standard angle bead, stop bead, arch bead, expanded metal corner bead and render beads in multiple widths.

What Is a Mesh Angle Bead?

• An L-shaped or U-shaped metal strip fixed to wall and ceiling corners before plastering or rendering
• The mesh or perforated wings let plaster key into the bead for a strong bond
• Protects external corners from impact damage and gives a straight, sharp finished edge
• Used in internal plastering, external render, stucco and drywall finishing

Profiles Produced

• Standard metal angle bead (90° L-profile)
• Expanded metal corner bead with mesh wings
• Arch and flexible corner bead
• Stop bead and movement bead
• External render corner bead

Key Features

• Quick-change tooling for multiple profile types and widths on one line
• 15 forming stations for accurate, consistent bead geometry
• Servo tracking cut-off cuts to length without stopping the line
• Length set by encoder counting or by photoelectric detection of punched holes
• Adjustable straightening rolls remove coil curvature and residual stress before forming
• Edge guiding system keeps the strip centred on entry
• Forged Cr12 rollers and forged 45# steel shafts for long service life

How the Production Line Works

• Decoiling: The coil is loaded onto an uncoiler with tension control for steady feeding
• Straightening: Adjustable rollers remove coil curvature and residual stress
• Edge guiding: The strip is centred as it enters the forming section
• Roll forming: 15 stations bend the strip step by step into the finished bead profile
• Servo cutting: The tracking cutter measures length by encoder or detects punched holes with a photoelectric sensor, then cuts on the move
• Run-out: Finished beads are collected on the run-out table for stacking and packing

Applications

• External corners on plastered and rendered walls
• Drywall corner protection and finishing

Frequently Asked Questions

• What material can the machine form? Galvanized and pre-painted steel coil from 0.3 to 0.5 mm thick.
• Which bead profiles can one machine make? Standard angle bead, expanded metal corner bead, arch bead, stop bead and render corner bead, using quick-change tooling for different profiles and widths.
• How fast does the line run? Up to 30 m/min, depending on the profile.
• How is cut length controlled? A servo-driven tracking cutter sets length by encoder measurement or by detecting punched holes with a photoelectric switch, and cuts without stopping the line.
• What are the rollers made of? Forged Cr12 steel, mounted on forged 45# steel shafts.
• What after-sales support is included? A one-year warranty with engineer support.
• What do you need for a quotation? Your bead profile drawing or sample, material and thickness, required output, and local voltage and frequency.
