Leading-edge automated manufacturing of wall elements, with great precision and high quality: accelerated project schedules, streamlined on-site assembly and a substantial reduction in labour. Configured to the walls you actually build, from a frame line to fully closed insulated panels.

Integrated wall element manufacturing: framing, handling, sheathing, routing and finishing in one controlled flow.

FRAMING MATERIAL

Timber or light gauge steel

AutoWall is one platform for timber and light gauge steel. The framing is where they differ: steel is framed on an LGS framing station, a different machine from timber framing, so each line frames one material. The rest of the line is the same: sheathing, membrane, insulation, turning and stacking. LGS framing comes at two levels of automation: manual assembly at the LGS framing station, or an automatic screwing station for higher output.

STATIONS & OPTIONS

Stations & options, configured to your factory

The framing area can be configured in several ways to optimise production flow based on the desired output level and factory footprint.

AutoWall production line layout with the eight stations numbered along the line
Example layout. Every AutoWall line is puzzled together around your products, output, factory and building system — we plan the exact layout with you in a pre-study.
Station 1

Framing

The start of the line, where the timber frame of bottom plate, top plate, studs and sub-elements is assembled and nailed square before it moves on.

The same station slot, framing in light gauge steel instead of timber. From the frame on, the element runs the same AutoWall stations.

Randek AutoWall timber framing station with automatic stud feeder
Randek LGS framing station for manual assembly of light gauge steel frames
Standard
FM3 framing station

The automated framing station positions and nails studs, plates and noggins from the CDT file, and squares the frame before it leaves.

Option
Automatic stud feeder

Feeds studs from packages straight off the trolley.

Option
Top & bottom-plate feeder

Feeds bottom and top plates into the station.

Option
Noggin machine

Cuts noggins to the actual distance between the studs, so stud-thickness deviation does not carry into the element.

Option
Crown check & Auto Reject

Lasers inspect each stud, flip it so the crown faces the same way, and reject studs outside the bending range.

Standard
LGS framing station

Upper and bottom screwdrivers fasten the studs into the top and bottom plates in one station; plate and stud stops set the position and the operator builds each frame by hand.

Automatic
Automatic screwing

Driven from the CAD/CAM file: the frame is fed forward automatically in steps, and up to six automatic screwing units, three above and three below, drive the screws from both sides.

Station 2

Sub-assembly

Timber only

Builds the fiddly subcomponents that go into the frame: rough openings for doors and windows, and the various multi-studs.

Manual
Manual sub-assembly

Rough openings and multi-studs assembled at a work station.

Robotic
ZeroLabor Robotic Sub-assembly

Robots build rough openings, U- and L-studs, doubles, triples and noggings, with a buffer that sequences them for the line.

Station 3

Sheathing

Boards laid on the frame and fastened, with openings cut and edges formatted. The step with the widest choice of automation.

AutoWall robotic sheathing cell (R4), isometric view
Standard
RB3 nailing bridge

A travelling bridge fastens boards to the frame automatically from the CDT file, with 1–8 fastener tools for clamping, nailing, screwing or nail pushers. Boards placed by the operator.

Automatic
Sheetsaw S3 + RB3

The Sheetsaw S3 cuts and lays the boards automatically ahead of the RB3 bridge, for automatic sheet placement.

Robotic
ZeroLabor Robotic Sheathing (R2–R5)

Robots handle, saw, glue, fasten and format the sheets, cut openings and change tools; scales from two to five robots.

Station 4

Membrane

Applying the membrane to the sheathed face before the element is turned.

AutoWall double membrane unwinder applying membrane to the sheathed face
Standard
Membrane application

A holder secures the membrane with automatic or manual feed and an automatic cutting blade, cut to length from the CDT file or by the operator.

Station 5

Turning

Turning the element to reach its reverse side, so the second face can be closed and insulated.

AutoWall turning system for full-size wall elements, isometric view
Standard
Turning system

A hydraulic upriser and receiver flip full-size elements safely without cranes, under a hold-to-run control.

Station 6

Insulation

Insulating the closed element, cavity by cavity, before the second face is closed.

Manual
Manual insulation

Insulation fitted by hand at a work table.

Robotic
ZeroLabor Robotic Insulation

Two robots blow insulation into each cavity to the density set by the CDT file, with a weighing protocol for quality control.

Station 7

Manual work

A working table built into the line for the steps that stay in human hands: membrane, electrical boxes and conduit, finishing details, while the line keeps its flow.

AutoWall operator work table built into the line, isometric view
Standard
Operator work table

Width adjusts to the element from the CDT file; the HMI shows the work for each element, with area safety scanners so the operator works while the line runs.

Option
LAP CAD-PRO laser projection

Projects the element layout onto the table to guide the manual work.

See it →
Option
Membrane cutting, scanners, cover plates

Add-ons matched to the work done at this station.

Station 8

Stacking & storage

The outfeed where finished elements leave the line, received, collected and readied for storage or transport.

AutoWall end-of-line stacker
Manual
Panel Lifting Tool

The operator-run way to close the line.

See it →
Standard
Automated end-of-line stacking

Horizontal or vertical stacking as volumes grow, with stack order set in planning by the Multiwall function.

Option
Roller-rack storage

Adjustable and angled storage systems behind the stacker.

THE FOUR LINES

Which AutoWall line is right for you?

The four line types share one base platform. What differs is how much of the wall you close, and how much of it you automate.

THE DATA CHAIN

Your CAD file drives the line

Designers create the building and wall element drawings in their own CAD software. All major timber framing CAD applications can export to Randek machines as a .cdt file, which the machines interpret directly. The file can be opened and verified in Randek Viewer and transferred into Randek Planner. Randek also provides fully automated APIs so an ERP or SCADA system can control planning via API calls.

QUESTIONS

What buyers ask first

What is the longest wall element the line can produce?
12,000 mm (40 ft in North America). The line is built around the maximum element length at each station, in increments of 1200 mm, so the shortest configuration is 6000 mm (20 ft).
How tall can the elements be?
2100–3300 mm as standard and 2400–3900 mm with the extended option (6.9–10.8 ft and 7.87–12.82 ft). The height range is the same at every element length.
What is the difference between open and closed panels?
Sheathing: one side on the open panels line, both sides on the closed panels line. Membrane is an option on every line. Closed panels also include the turning system as standard; on the open panels line an upraiser is available as an option.
Which CAD systems can drive the line?
All major timber framing CAD applications can export to Randek machines as a .cdt file, which the machines interpret directly. Randek also provides fully automated APIs so an ERP or SCADA system can control planning via API calls.
Can the line be automated with robots?
AutoWall Frame: ZeroLabor Robotic Sub-assembly. AutoWall Open Panels: One or two ZeroLabor R2, or Sheetsaw S3 with bridges for maximum single-layer speed. AutoWall Closed Panels: ZeroLabor R3 + Robotic Insulation. AutoWall Mixed Panels: Robots or bridges.
Can I automate only part of an existing wall line?
Yes. Robotic sub-assembly, sheathing and insulation cells retrofit onto AutoWall lines already in production, and stations can be added one at a time. See how to choose the right level of automation.
Does the line handle light gauge steel as well as timber?
Yes, as an AutoWall for light gauge steel. Each AutoWall is built for one material: a timber line has a timber framing station and a steel line an LGS framing station. Sheathing, nailing, routing, membrane, turning and stacking are the same stations for both.
