Folding Mechanism for Dough Laminators

Product Specifications

Technical details and manufacturing context for Folding Mechanism

Definition

The folding mechanism is a critical component of an industrial dough laminator responsible for creating the layered structure in laminated dough products like croissants, puff pastry, and Danish pastries. It operates by systematically folding dough sheets over butter or fat layers to create multiple alternating layers, which expand during baking to produce the characteristic flaky texture. The mechanism typically consists of synchronized rollers, guides, and folding plates that receive the dough sheet from the sheeting rollers, then precisely fold it according to predetermined patterns (such as single folds, double folds, or book folds). The folding action is controlled through mechanical linkages, pneumatic systems, or servo motors to ensure consistent layer alignment and thickness. Constructed from food-grade materials, the mechanism is designed for hygiene and durability in continuous production environments. Key specifications include folding accuracy of ±0.5 mm, production capacity of 500–2000 pieces per hour, dough thickness range of 1–25 mm, and programmable layer count from 3 to 32 layers. Operating pressure is 0.6–0.8 MPa, supply voltage is 380–480 V AC (IEC 60038), and power consumption ranges from 2.2 to 5.5 kW. The mechanism operates within 0–40 °C ambient temperature, has ingress protection ratings from IP54 to IP65 (IEC 60529), and is available in stainless steel grades 304–316 (ASTM A240). Weight ranges from 350 to 800 kg, and footprint dimensions vary from 1500×800×1200 mm to 2500×1200×1800 mm. These values are directory references and must be verified with the legal manufacturer for specific models and applications. The folding mechanism is a component, not a standalone machine, and requires integration with a laminator system. Proper selection depends on dough characteristics, desired layer count, and production line layout. Maintenance signals include unusual noise, misalignment, or inconsistent fold quality, which may indicate wear or adjustment needs. Failure boundaries include operation outside specified temperature or pressure ranges, which can affect performance and component life.

Working Principle

The folding mechanism receives a dough sheet from the sheeting rollers. Synchronized rollers, guides, and folding plates then fold the dough according to a preset pattern, such as single, double, or book folds. The folding action is driven by mechanical linkages, pneumatic cylinders, or servo motors, ensuring precise layer alignment and thickness. The number of layers is programmable via PLC, typically from 3 to 32. The mechanism operates within specified pressure and temperature ranges to maintain accuracy.
