The combination of the cross-cutting unit and the brushing unit allows for the creation of various effects, including authentic band saw textures and other natural surface patterns. The machine features a TAP function that enables the application of a random effect to the workpiece. This is achieved using five separate tapping heads above the sanding belt. A compressed air connection is required for the operation of this function. By adjusting the transport speed, the settings of the cross-cutting unit, and the brushing unit, the intensity of the process can be easily controlled. This allows for the creation of a wide range of textures and finishes, depending on the desired end result. The machine is suitable for processing various wooden products, including wooden floors, wall panels, furniture components, doors, and other wooden products where a distinctive surface texture is desired.

Condition: ready for operation (used), Year of construction: 2005, functionality: fully functional, type of input current: three-phase, !! This machine comes with a donor machine that can be used for spare parts. !! The Nordson FoamMelt 200 (FM 200) is a specialized dispensing system that mixes hot melt adhesives with an inert gas (such as nitrogen) to create a closed-cell foam. This process reduces adhesive consumption by as much as 50% to 65% while improving bond performance. Applications: Widely used for bonding, sealing, gluing, and gasket making in the automotive and packaging industries. Benefits of FoamMelt Technology Faster Curing: The foam cools down faster, enabling higher production speeds. Better Filling Properties: Lrjdey N Ahcepfx Ah Sou The volume increase due to the gas makes it ideal for filling gaps. Improved Safety: The lower heat density of the foam reduces the risk of burns for operators.
