The crank actuators 50 cause the reciprocating movement of the heating devices. 1-6. The plywood intended for drying is pushed into the first pair of rollers, sequentially captured by the remaining pairs and pushed through the entire machine. When the roller pairs are pushed through, the plywood is guided by heated guides 20-25 and then cooled by 1 mn guides 26 and 27. Heaters moved by means of a crank drive 50. back and forth over passing under. plywood and their drying, rather than heating devices, can be done. The plywood directly touches the plywood, moving its drying distance close to the plywood. Since the movable and fixed heaters located in the first place, in spite of the passage of plywood, have a lower temperature than the devices in the middle of the flock, the drying takes place gradually, and not immediately, with the fagsera. QT drying does not suffer. Then from the middle of the heating device to the end of the machine, the temperature again gradually decreases, which ensures a smaller temperature difference during the transition from drying to cooling and the best protection of plywood from deterioration. By rotating the handwheel 63, all heating devices can be simultaneously installed in a certain position relative to the fixed guides 20-25, depending on the thickness of the plywood intended for drying. When the handwheel 63 rotates, all the rods 58 move horizontally and their inclined pads 56 slide along the inclined pads 55, causing a higher or lower installation of the bars 53 supporting the rollers 52 of the frames 45, 46, 48. Refer to Section 76, you can set the height of each individual heating The drive with stepped pulleys 177, 180, 160 makes it possible to regulate the speed of passage of the plywood 3 in relation to the movement of the equipment and thus to regulate the drying.
