The Control Stitch nozzle air jets attenuate and actuate adhesive fibers to produce a tight stitch pattern, delivering superior control of hot melt adhesive for reliable product performance.

Controlled adhesive deposition delivers strong bonds at high line speeds for continuous or intermittent applications. Use of process air improves nozzle cleanliness and assists in pattern cutoff in intermittent applications. The configurable nozzles provide operating flexibility for single or multiple adjacent lines to meet stringent adhesive application requirements.

Nozzles are compatible with Universal™ series modules. These include UM22 and UM25 modules for less demanding intermittent operations, Speed-Coat® module for high-speed intermittent lines, UM50 module for continuous operations, and UM3 module for metering applications.

A serviceable, surface-mounted elastomeric o-ring prevents leaks. The patented Universal module screw applies uniform nozzle clamping for a positive hydraulic seal and thorough heating. Nozzles are easily cleaned and withstand repeated handling. Common Universal parts minimize inventory costs and simplify service.

Improve bond strength and product performance in nonwovens construction applications.
