Transmission of drive power from the feed motor to the single feed rollers on planers and moulders
Chain drive
- with older machines until about the beginning of the 70´s
- common drive type with mechanics-regulated and frequency-regulated feed rate respectively, used on machines with a feed rate of 100-600m/min,
Hydraulic drive
- used on machines for high feed rate, approx. 100m/min as well as machines with a processing width larger than 220mm (e.g. Waco Solid profile sharping machine)
- single feed units will be driven directly, each with separate, frequency-regulated drive motor
- cheap engine version up to approx. 15m/min feed rate (e.g. WEINIG Unimat 300)
- saving of energy up to 15% in comparison to traditional feed rates on Hydromat 3500 by Waco
