The Alomat AL310 series is the latest development of our proven knot plugging machines. Its speed and precision are unrivaled. With 66 % energy savings compared to the predecessing series, you can work twice as fast: the Alomat AL310A-HGF's cycle time of just 2.2 seconds for real knot plugs speaks for itself! This machine can be used to plug either with real knot plugs or with pitch pocket plugs, one after the other, only by choosing the according foot valve. The the real knot plugs are fed from the container, the pitch pocket plugs with the help of the spiral conveyor.

Alomat AL310A-HGF works with workpiece clamping by lowering the unit. The advantage of this method: The height of the work table is not changed; the operating height always remains constant, regardless of the workpiece thickness. This also allows problem-free processing of long workpieces with a workpiece thickness of up to 170 mm.

A bulk material container is provided on the assigned machine arm for the real knot plugs and pitch pocket plugs. The left-hand machine arm is used to plug pitch pockets, the right-hand machine arm is used to plug real knots. The real knot plug container can store approx. 1000 Ø 25 x 8 plugs.

The plugging depth can either be 8 mm or 10 mm, with the workpiece clamping guaranteeing that the normal plug or real knot plug is pressed in without any protrusion.

Both the clamping stroke and the workpiece thickness compensation are performed from above. For this purpose, the processing slide (incl. drilling and milling unit, glue injection device and feed cylinders) is lowered.

The AL310A-HGF creates a tight fit of the normal plug by gluing the base and providing circumfrancial gluing to increases the mechanical load-bearing capacity and quality of the workpiece thanks to the enlarged gluing surface. This greatly increases the reliability of the patched areas compared to processes in which only the bottom of the plug is glued. The normal plug is pressed in up to the bottom of the drill hole and lies on the same level as the workpiece surface. This prevents the normal plug from being drawn into the drill hole when the glue diffuses into the workpiece. In addition, no glue pool is created and a volume of air between the normal plug and the base of the drill hole is avoided.

The precise injection of glue prevents an unwanted glue rim, so that the surface of the workpiece remains clean and can be processed immediately.

The glue rising groove depth is adjustable. This ensures that the gluing always withstands the upcoming stress on the workpiece and that your finished wood retains its high quality.
