  • Furniture and appliance fabrication

Benefits of roll formed metal panels:

  • Consistent quality and precision along the length
  • Flexibility in profiles and gauges
  • Higher strength than sheets
  • Faster production than custom brake forming
  • Lower material waste

Roll forming lines can produce various panel shapes like corrugated, ribbed, fluted, or flat. Popular siding profiles include vertical board & batten, horizontal lap siding, shiplap, and Dutch lap seam.

Types of Siding Panel Roll Forming Machines

There are two main types of roll forming equipment:

Inline Siding Panel Roll Forming Lines

  • Coil fed from a de-coiler enters inline stations to gradually shape the profile
  • Stations perform operations like feeding, punching, cutting, rolling, and hemming
  • Formed panels exit the line into a cutoff press for length cutting
  • Produces panels up to 18 feet long
  • Length determined by cutoff press cycles
  • Suitable for high volume production

Rotary Siding Panel Roll Forming Machines

  • Coil loaded on a reel passes through a rotating forming head
  • Rollers continuously bend the strip into the desired contour
  • Panels exit and are cutoff to length by rotary saws
  • Quick changeover between profiles
  • Lower volumes and shorter lengths
  • Portable and occupy less space

Key Components of a Siding Panel Roll Forming Line

A complete siding panel roll forming system consists of:

  • Uncoiler: Feeds metal coil strip into the line
  • Feeding unit: Controls strip speed and tension
  • Punching unit: Punches holes for fasteners
  • Pre-cutting unit: Cuts insulation slits and notches
  • Forming stands: Bend and shape the profile through progressive rolling
  • Post-forming operations: Hemming, punching, de-oiling
  • Cutoff press: Cuts formed panels to specified lengths
  • Exit conveyor: Transfers finished panels from the line

Additional equipment like stacking tables, embossing presses, and automated bundling can be integrated for material handling.

Uncoilers for Siding Panel Roll Forming

The uncoiler holds large coils of flat sheet metal and feeds the strip into the roll former. Key features:

  • Coil capacities up to 25 tons
  • Powered unwinding by AC motor with brake
  • Rubberized rollers for non-slip grip
  • Dancer roll tension control system
  • Coil car for quick loading and changeover

Punching Units

Punching units create holes in the strip for fasteners like nails, screws, and rivets used to install the final siding:

  • Available with single or multiple punching heads
  • Pneumatic, hydraulic, or servo-electric punch drives
  • Tooling dies for round, slotted, or shaped holes
  • Programmable spaces between holes
  • Stripping units prevent material jamming

Pre-Cutting Stations

These stations cut longitudinal slits or notches in the strip before roll forming:

  • Rotary slitters for insulation ventilation slots
  • Guillotine shear knives for edge notching
  • Servo-electric or hydraulic actuated
  • Reduces additional secondary prep work

Roll Forming Stands

The heart of the machine, forming stands progressively bend the strip into the final profile:

  • Typically 10-16 stands in the line
  • Each stand contains top and bottom rollers
  • Rollers machined to gradually form the contour through small increments
  • Roller diameters, angles, and spacing determines the profile
  • AC motor drives with gearboxes rotate the rolls

Common siding profiles utilize different combinations and sequences of the following forming operations:

  • Breaking: Initial bending from flat strip into simple angles
  • Flanging: Bending perpendicular to the strip direction
  • Corrugating: Creating waves or ribs transverse to the strip
  • Beading: Forming specialized shapes on edges
  • Hemming: Folding over edges for safety and appearance
  • Profile cutting: Trimming excess material

Post-Forming Sections

Additional operations are done after initial roll forming:

  • Corner notching: Cutting to form overlap joints
  • Auto-punching: Adding holes for easy installation
  • De-oiling: Removing lubricants from the forming process
  • Hemming: Folding panel edges for safety and aesthetics
  • Embossing: Applying surface patterns and textures

Cutoff Presses

Formed panels are cut to specified lengths by the cutoff press:

  • Electro-hydraulic or servo-electric presses with automatic cycles
  • Actuated upper blade shears panels like a giant paper cutter
  • Lengths from 2 feet up to 24 feet
  • Length tolerances within ±1/16″
  • Programmable panel length, counter, and batch size

Exit Conveyors

Motorized exit conveyors transfer cut panels out of the line:

  • Roller or belt type conveyors
  • Adjustable speeds and elevation
  • Lengths up to 40 feet
  • Allows panels to be stacked or bundled
