Four pneumatic clamps securing mouldings firmly throughout the cutting stroke
Smooth mitre cuts on workpiece sections up to 80 mm high and 100 mm wide
Direct integration with automated programmable length measurement gauges

Alfamacchine electronic length measurement systems AG-2000 and AG-20000

Electronic stop gauges AG-2000 automate linear workpiece dimensioning across double mitre saws. Featuring programmable servo motor positioning, touchscreen length entry, and stored cutting recipes, the system removes operator positioning variance during repetitive production.

Precision linear carriage positioning with positioning repeatability within 0.1 mm
Touchscreen terminal preloaded with dimensional programs for framing jobs
Automatic moulding width compensation and mitre corner allowance offsetting
Synchronized operational interlocks with pneumatic saw blade drop actuation

Alfamacchine Power Twist V-Nail fasteners and Flexi Tabs framing hardware

Standard Power Twist V-Nails are manufactured from high-strength carbon steel with specialized silicone friction coating for effortless penetration into timber. The patented taper geometry pulls corner joints tightly together, producing permanent structural corner strength.

Fastener heights of 5, 7, 10, 12, and 15 mm for softwoods, hardwoods, and MDF
Patented Power Twist pulling geometry for tight 45-degree corner joint fit
Silicone lubricant coating along fastener strips minimizing magazine wear
Flexible Flexi Tabs and rigid Hard Points for framing backboard retention

Manufacturing heritage of Alfamacchine and production plant in Forli

Italian engineering manufacturer Alfamacchine was established in 1981 in Forli, dedicating over four decades to engineering precision joining equipment for the picture framing and woodworking industries.

The plant maintains modern design bureaus, automated assembly lines, and testing facilities for pneumatic and computerized machinery.

Operating under the global Fletcher Business Group, the enterprise retained full mechanical engineering and fabrication operations in Italy.

Engineers develop specialized machinery for assembling art frames, mirrors, door trim, and architectural mouldings, guaranteeing tight joint closure and long operational reliability across manufacturing shops.

Engineering features of U-200 and U-300 underpinners for framing shops

The manual U-200 mechanical underpinning machine is actuated via an ergonomic foot pedal, operating completely without compressed air lines or electrical power connections.

Its compact footprint, tilting base structure, and sturdy mechanical assembly make it an ideal selection for bespoke custom framers and art studio workshops.

The semi-automatic U-300 pneumatic machine incorporates a smooth sliding carriage and adjustable mechanical stops for flexible fastener positioning.

The operator maneuvers moulding sections across the driving head, inserting single or stacked fasteners into predefined joint locations across softwoods, hardwoods, and synthetic profiles.

High-capacity computerized underpinners U-500 and U-600 with CNC automation

Computerized U-500 and U-600 underpinning systems are designed for demanding multi-shift production environments in door trim, architectural millwork, and volume frame manufacturing.

Featuring touchscreen interfaces with memory storage for 5,000 moulding profiles, machines permit swift changeovers using automated barcode scanning.

The advanced U-600 production joiner incorporates a multi-channel fastener magazine, enabling the machine to drive different fastener heights into a single corner joint in one cycle without manual retooling. The automated C.A.P.S.

mechanism regulates clamping force, protecting delicate decorative surfaces from pressure markings.

Double mitre saws T-400 and automated cutting centers TA-350

Alfamacchine T-400 double mitre drop saws execute simultaneous 45-degree angle cuts with high angular accuracy.

Twin circular saw blades are mounted upon a unified vertical stroke carriage powered by a pneumatic cylinder, providing synchronized cutting with minimal scrap generation in timber and composite mouldings.

During each cutting cycle, the workpiece profile is firmly locked by four independent pneumatic hold-down clamps, eliminating deflection or vibration.

Automated TA-350 cutting lines integrate powered infeed conveyors and AG-2000 programmable stop gauges, delivering high-speed repetitive cutting across production facilities.

Corner joining technology with Power Twist fasteners and Flexi Tabs

Patented Alfamacchine Power Twist V-Nails are cold-formed from high-tensile carbon steel strips coated with friction-reducing silicone.

When inserted into wood, the distinctive tapered geometry pulls mitered edges inward, producing an extremely tight corner joint without relying on manual bar clamps or slow-curing adhesive.

Fasteners are produced in heights ranging from 5 to 15 mm, with specific grinds engineered for softwoods, dense hardwoods, MDF, and extruded polymers.

For backboard and glazing retention, Alfamacchine provides flexible Flexi Tabs and hardened steel Hard Points, enabling clean frame closure without distorting delicate artwork.

Preventive maintenance protocols, driver blade selection and clamping pads

Continuous equipment uptime depends upon timely replacement of high-wear mechanical components: hardened V-Nail driver blades, carriage return springs, and pneumatic cylinder seals.

Driver blade tip wear leads to incomplete fastener embedding and potential magazine jams, requiring regular dimensional inspection.

The Clamping Pad System offers magnetic and quick-change clamping heads in varied durometers and profiles: round, angled, and contour shapes for complex mouldings.

Technicians assist in identifying compatible spare parts, carbide saw blades, and pneumatic valves using factory serial nameplates and assembly drawings.
