Abstract
A panel sawing machine comprises a horizontal table (5) on which a movable device (6) pushes a stack of panels (3a) in a forward direction (F) or reverse direction (F1) to feed a sawing device (or to a device for rotating the stack) which divides the panel up into two or more smaller boards. The pusher (6) is equipped with two or more pickup elements (16) that hold the rear edge of the stack in position during positioning and/or sawing operations. The pickup elements (16) are mounted on the movable device (6) in such a way that they can run in guides (15, 15a, 15b) in the following three directions, respectively: horizontal at right angles to, and horizontal parallel to, the forward direction (F) or the reverse direction (F1), and vertical.

A method for cutting panels in a panel sawing machine, said method comprising:
- positioning at least two pickup elements (16a, 16b, . . . 16n) mounted on a movable device (6;6a) at a rear edge of at least two panels (3a, 3b, . . . 3n), respectively;
- engaging the rear edge of the at least two panels (3a, 3b, . . . 3n) by said at least two pickup elements (16a, 16b, . . . 16n), respectively;
- pushing simultaneously the at least two panels (3a, 3b, . . . 3n) along a feed direction (F;F2) toward a sawing device (7;
- 7a) by moving said movable device (6;
- 6a) together with said at least two pickup elements (16a, 16b, . . . 16n) in the feed direction (F;F2);
- moving at least one panel of said at least two panels (3a, 3b, . . . 3n) with respect to the other panel of said at least two panels in the feed direction (F;F2) or in the direction (F1;F3) opposite to the feed direction (F;
- F2) by moving at least one of the at least two pickup elements (16a, 16b, . . . 16n) relative to the movable device (6;6a) in the feed direction (F;F2 or the direction (F1;F2) opposite the feed direction to position respective cutting lines of said at least two panels along a cutting axis of the sawing device (7;
- 7a);
- and,
- after positioning the respective cutting lines of said at least two panels along said cutting axis of the sawing device, cutting the at least two panels (3a, 3b, . . . 3n) along their respective cutting lines by the sawing device (7;
- 7a) into two or more smaller boards (40, 41, . . . 4n) in a direction at right angles with respect to the feed direction (F;
- F2).

- F2) or in the direction (F1;
- F3) opposite to the feed direction (F;
- F2) to position respective cutting lines of said at least two panels along a cutting axis of the sawing device (7;
- 7a);
- and,
- after positioning the respective cutting lines of said at least two panels along said cutting axis of the sawing device, cutting the at least two panels (3a, 3b, . . . 3n) along their respective cutting lines by the sawing device (7;
- 7a) into two or more smaller boards (40, 41, . . . 4n) in a direction at right angles with respect to the feed direction (F;
- F2).
