Needling

Schober USA, who is partnered with a European company for more than 25 years, has been providing needling equipment for many market areas. Through this experienced collaboration, we can provide you with proven technology for cold or hot needling applications. VentPerf systems are available as in-line, off-line modules and systems for all your needling applications.

VentPerf-Cold is designed for micro-hole patterns while VentPerf-Hot provides consistent quality reinforced holes in film materials. Both, in their individual sectors, are ideal for film materials and applications for the production of breathable products when moisture release is an issue.

The hole sizes are adjustable and tools for virtually any hole pattern are available. This innovative system can achieve up to 600 ft/min and 250 holes per sq. in. with no special operator skills required.

VentCut is ideal for agricultural and packaging products that require enhanced air flow and structural expansion.

VentPerf - Cold

The two VentPerf-Cold systems vary in the size of the needle and anvil rolls. This variety allows increased speeds and a higher needle density with possible speeds up to 600 ft/min and up to 250 needles /sq inch.

 

The VentPerf-Cold systems are easily integrated into in-line processes. The VentPerf-Cold – M is also available as a stand-alone system with unwinds and rewinds. Pneumatically activated lowering is available as an option for both the VentPerf-Cold – S and VentPerf-Cold – M. The optional motor driven needle roll and a slave system for automated processes are only available for the VentPerf-Cold – M.

VentPerf - Hot

The three available VentPerf-Hot systems vary in the amount of energy drawn, diameter of the needle roll and frame strength. This allows improved speed ranges and a higher needle density.

 

All three VentPerf systems are also available as stand-alone systems with unwinds and rewinds. These new systems from Schober USA are made of corrosion-proof galvanized steel & stainless steel with spray painted frames. Digital temperature displays and temperature controls are standard features.

 

If integrated as In-Line Systems (slave), it will activate when the roll temperature is reached and brought up to web speed. The pneumatically activated thermo screen will open and the needle roll will be pneumatically lowered. At minimum speed or machine stop signal, the reverse automated action will take place. The systems may also run under operator control.
