The Industrial Sawmilling Lines, also known as WoodMizer Systems, introduce automation and smart solutions to produce timber efficiently at lower costs. The presented TVS HD Twin Vertical Saw is a part of the WoodMizer Systems Industrial Sawmillng Line with the HR700 horizontal resaw, the MR200 doublearbor multirip (also called a gangsaw), and the log loading deck, infeed, and outfeed tables, transfer tables, and sorting tables.

The horizontal deck at the beginning of the line is used for loading the logs onto the TVS HD infeed table. The outside part of the deck has been accommodated from the existing system and enables the stocking of the logs for continuous operation. WoodMizer offers loading decks with 3,6, or 6 mlong conveyors (12” or 20”), which can be easily customized to individual manufacturing needs.
The log deck is coupled with an inclined loading deck with arms that feed the TVS HD vertical saw. Once the log is on the infeed table, it is secured from the top by holddown spiked wheels and transported on a chain with sprockets. The infeed table is synchronized with the loading deck, so the holddown wheels move up at loading.

The operator monitors the cutting process from the control panel placed in front of the TVS HD. There is a joystick for loading, positioning, and feeding the logs and a setwork for adjusting sawing parameters, such as positioning and distancing the saw heads. Above the control panel, the operator can watch the process closely thanks to four surveillance cameras.

The twinhead vertical saw TVS HD was designed for processing logs with a diameter of 150 – 450 mm and a length of 120 – 520 cm. “On customer request, the engineers can customize the length to the required dimensions, e.g., 100 – 350 cm,” says Adam Kubiak, WoodMizer Industrial Sales Manager. “Compared to the standard TVS vertical saw, the HD version is elevated about 254 mm above the ground to facilitate cleaning and allow the conveyor belt to collect the sawdust from under the saw heads. The standard TVS vertical saw features a single belt to transmit the power from the motor (11 kW, 15HP) and run the blades, while in the HD version, two separate belts are allowed to utilize more robust electric motors (18,5 kW, 25 HP).”

In the TVS HD, two types of blades can be used to break down logs – the standard 38mm wide blades or the 50mm wide blades (2inch). The blade tensioning system is based on a manual hydraulic pump with a measuring gauge, feeding both sawmill blades. It is assisted by a pressure sensor, which can turn off the entire sawmilling line in case of a sudden pressure drop (e.g., blade breakage).

The outfeed table of the TVS HD features side discs and holddown rollers controlled by optic sensors. The main task of this mechanism is to hold the 2sided cant steady and feed it to the transfer table down the line. After separating the cant from the slabs, the side discs allow for a controlled fall of these slabs onto the incline transfer deck that transports the slabs away from the machine into another processing machine (in this case, it is a customer’s existing machine incorporated to the TVS HD sawmilling line). At the end of the TVS HD outfeed table, the final holddown wheel moves sideways to turn the cants over to horizontal orientation. The cant is forwarded on a conveyor to another machine in the next step.
