Holz-Her Sprint 1321 edgebander is a high-quality machine, ideal for the needs of carpenters and companies working with wood panels. Manufactured in 2006, this used machine stands out for its solid construction and precision components that ensure reliability and longevity.

Visual appearance and main components

Visually, the Holz-Her Sprint 1321 appears to be a robust and compact machine, with a main body approximately 6480 mm and a weight of 1900 kg . It is designed to efficiently edge panels of various sizes thanks to the pressure bridge . Among the main components we find:

• Automatic edge feeder , which facilitates the feeding of edges during processing.
• Multi-adhesive group , capable of working with EVA and PVR both in cartridges and granules.
• Pneumatic pressure group , equipped with 3 pressure rollers, one of which is motorized for constant pressure on the edge.
• Double motor end trimming unit , with a power of 0.45 kW per motor, capable of reaching a speed of 12,000 rpm .

Mechanical characteristics and use

The edgebander is equipped with a numerical control (NC) system that automatically manages various processing parameters. This machine can process panels of varying thicknesses, automatically adjusting the grinding unit to ensure impeccable precision at all times. The Holz-Her Sprint 1321 can also perform edge trimming and rounding operations, thanks to 0.65 kW and 0.40 kW , also electronically controlled.

Usage procedure

The edge banding machine's operation is quite simple: after setting the panel thickness, the automatic feeder inserts the edges, which are secured using the multi-adhesive unit. Pressure rollers apply constant pressure during gluing. The end trimming units then trim the excess, and the trimming unit trims the edges for a perfect finish.

Accessories and areas of use

The machine can be combined with suction devices and surface cleaning systems, such as integrated cleaning brushes. It is primarily used in carpentry, furniture manufacturing, and custom-made furnishings.

Usage parameters and mathematical formulas

To ensure optimal use of the machine, it is important to monitor the processing speed and the pressure exerted by the rollers. The suction capacity is 2860 m³/h , while the required compressed air pressure is 380 liters/minute .

Maintenance and safety

Maintenance of the Holz-Her Sprint 1321 includes regular cleaning of the internal components and pressure rollers, as well as periodic inspection of the pneumatic system and header blades. For safety, it is essential to check the integrity of the guards and ensure that the electrical system is up to standard. If the machine is not CE certified, it is possible to adapt it to current requirements with a safety system upgrade.

Advantages of buying used

Purchasing a used edgebander like the Holz-Her Sprint 1321 is extremely advantageous for those seeking reliability and precision at a reasonable cost. A well-maintained used machine can offer performance comparable to a new one, with the advantage of a lower price and faster payback period.
