Wrinkles and air gap – Case #020

August 21, 2012


“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce their products Right from the Start TM.

Problem: wrinkles and air gap on the upper near the back seam due to improper attachment of the solvent-based counter-stiffener to the upper.

Impactiva Solution: we got the factory to use a hot air blower machine to soften the solvent-based counter-stiffener before attaching it. And then perform a counter molding operation in order to obtain the correct back shape. These procedures completely avoided wrinkles and air gaps in the upper.
