Wood strips are supplied by the operator to the truck of the milling tenoner. Supply of elements initiates the miller work cycle. The stack face is levelled, after which milling of the finger joint outline is carried out. The miller truck returns to its starting position with preliminarily processed elements and returns the stack to the rotating supply table, where it is rotated. The stack is once again supplied to the milling tenoner, where the other side of the stack is processed.

OPERATION DESCRIPTION
Wood strips are supplied by the operator to the truck of the milling tenoner. Supply of elements initiates the miller work cycle. The stack face is levelled, after which milling of the finger joint outline is carried out. The miller truck returns to its starting position with preliminarily processed elements and returns the stack to the rotating supply table, where it is rotated. The stack is once again supplied to the milling tenoner, where the other side of the stack is processed.
Elements supplied from the DFC - 60 M tenoner through the chain conveyor are introduced to the preliminary tenoning unit, where preliminary clamping of the wedge-joints of square-sawn timber is carried out by means of a set of cylinders and a pressure pad before its introduction into the press.
The preliminarily tenoned square-sawn timber is directed to the press table, on which it is cut after achieving the required length. Next, the wood is transported into the area of the pressing bed by means of a pushing strip and pressure strip, where the pressing process takes place. Glued and pressed, the ready strip is pushed onto the receiving table of the press.
After square-sawn timber is moved into the area of the pressing bed, the process of element supply onto the press table is carried out in parallel. This maintains continuous press operation and also makes it possible to improve the efficiency of glue spreading.
