Wood strips are supplied by the operator to the truck of the first milling tenoner. Supply of elements initiates the miller work cycle. The stack face is levelled on the first miller, after which milling of the finger joint outline is carried out. The stack is supplied to the table of the second milling tenoner, where processing of the other side of the stack and glue spreading takes place.

OPERATION DESCRIPTION
Wood strips are supplied by the operator to the truck of the first milling tenoner. Supply of elements initiates the miller work cycle. The stack face is levelled on the first miller, after which milling of the finger joint outline is carried out. The stack is supplied to the table of the second milling tenoner, where processing of the other side of the stack and glue spreading takes place.
Elements supplied from the DFC - 60 D 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.
