• Swing-Type Cross Conveyor Lifting Motor Power: 1,1 kW

Basic Features

• Purpose: Built for robust, fast, and intelligent feeding of wood pieces into a four-side molder.
• Rollers: Five active, smooth, hardened bottom rollers and five passive top rollers equipped with pneumatic cylinders and 2-stage variable pressure.
• MAX model feature: Two separately driven active roller sections for independent adjustment of roller speed in the cross-feeding section and the acceleration section
• Side Pressure Roller: Positioned just before the molder infeed table to ensure the correct position of the board into the molder.
• Floating Table: Adjustable pneumatic cylinder support to ensure smooth material infeed into the molder, even for bent material.

Anti-Jamming Features

• Real-Time Speed Monitoring: The ErgoTakSmart system uses an encoder on one of the passive rollers to obtain real-time board speed information, maintaining constant awareness to ensure smooth operations.
• Anti-Jamming Mode: Automatically adjusts to changes in material speed into the molder, detecting the onset of material jamming and applying increased pressure with the top rollers. If the attempt is unsuccessful, it automatically stops the infeed.
• Swing-Type Cross Conveyor: Fast motor drive operated (instead of pneumatics – MAX model feature), allowing boards to rest on supports during each feed to prevent extra side pressure on boards and ensure smooth feeding into the molder.
• Finger-Jointed/Heavy Boards Mode: Creates gaps between boards to prevent any tension from the cross-feed conveyor side.

Flexible Range Feature for High-Speed Operation

• Thickness Range: Designed to work with a thickness range of 10 mm to 150 mm, with motorized lifting of the upper beam supporting pressure rollers and digital thickness setting via HMI.
• Adjustable Height: Allows for the use of high-speed pneumatic cylinders with a short stroke, enabling fast operation and reducing changeover time between boards.

Load Reduction Features

• Smooth Powered Bottom Rollers: Allow board-to-board material slippage to prevent excessive kick-type loads on the four-side molder gear system.
• Automatic Speed Adjustment: Infeed speed automatically adjusts to match the molder speed based on encoder data to prevent excessive loads on the four-side molder gear system.

Control System: ErgoTakSmart
