Automatic Knot Plugging Machine - Alomat AL100

Alomat AL100 at a Glance:

• Automatic plugging of wood defects with normal plugs from batten
• Cycle time 3.5 s
• Workpiece clamping by elevating the working table
• 10 mm clamping stroke
• 15 mm bis 35 mm normal plug diameter
• 6 mm bis 16 mm normal plug thickness
• Circumferencial gluing of normal plugs by means of glue rising grooves

Our Alomat AL100 single-spindle automatic knot plugging machine allows for efficient plugging of knots, pitch pockets and swirls in wood. This refining of low-grade timber improves its quality and extends its range of application. Convince yourself of the advantages of this tried and tested technology and benefit from our years-long experience in the field of electro-pneumatically controlled automatic knot plugging machines, dating back to 1965.

The Alomat AL100 works with workpiece clamping by elevation of the working table. The upper side of the workpiece is clamped and aligned in such a way that the normal plug is pressed in without protrusion, regardless of the height tolerances of the workpiece and with a constant reference surface. Workpieces up to 140 mm high can be clamped and plugged. The clamping stroke is 10 mm.

Glue rising grooves (see illustration), which are automatically inserted on each normal plug, allow the glue to rise laterally along the circumference of the normal plug in glue channels towards the workpiece surface. The glue rising grooves' 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.

The AL100 creates a tight fit for the normal plug by gluing the base and its circumference and, thanks to the increased gluing surface, improves the mechanical strength and quality of the workpiece and thus the reliability of the plugged areas compared to processes in which only the bottom is glued. In addition, there is neither a glue pool nor an air volume between the normal plug and the base of the drill hole. 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 plug from being drawn into the drill hole once the glue diffuses into the workpiece.
