Hotair welding machines are typically used to strengthen and seal seams in the textile and leather industry. Compressed air is heated up to several hundred degrees Celsius by electricity and is blown onto the tape coated with thermoplastic glue...

...the Innovation
ENERGY SAVING OF MORE THAN 90%

The innovation of the VETRON hotair welding machine is based on the development of a new air heater in combination with consistent reduction of heat losses and a newly designed air nozzle. The air supply can be stopped at any time without damage of the heater. The nanoporous thermal insulation and the optimization of the air channel are also reducing energy losses.
The new designed nozzle optimizes the energy transfer to the tape. As a result, the required amount of hot air could be reduced to a fraction.
Comparison tests revealed a possible ENERGY SAVING OF MORE THAN 90% compared to previous systems!

The VETRON 5700 // 5710 was designed as a quality assurance system for safety-related seams in the automotive industry.
It guarantees the precise control and documentation of seams, which serve as the nominal breakage point of the reference seam when the side airbag is triggered. Each stitch, top and bobbin thread in the docu seam is measured by the docu system and monitored according to the corresponding specifications. The 5700 // 5710 is thus an important link in quality assurance within the production chain.

VETRON STARTING THE CLASSIC SERIES

The VETRON 4000 series has been designed as a modern,fully equipped, mechanical industrial sewing machine for use in medium to heavy-duty applications and complements the portfolio with a classic industrial sewing machine in addition to the VETRON 5000 series.

With an exceptionally high stitch quality, it is perfectly suited for topstitching work in the visible area, as well as for assembling seams for use in automotive and upholstery production.

Equipped with a thread trimmer, thread clamp for a clean seam beginning. Switchable, second tension, second stitch length and top feed stroke. Recallable via the switch bar in the arm of the machine. With the built-in LED sewing light and an integrated touch control panel in the machine arm, the VETRON 4000 series offers all the features of a modern, classic industrial sewing machine.

Other features include are a powerful main drive and low-noise, low-vibration operation due to aluminum arm and head covers.

The sewing gauge parts set of the VETRON 4000 series is identical to the VETRON 5000 series and can therefore be used as an original part in VETRON quality for all VETRON series. As a result, the VETRON 4000 series fits easily into the VETRON range and is an ideal operating resource and reliable partner.
