Waviness on topline of boot – Case #172

“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 Right from the Start TM.

Problem: Waviness on the topline folding. This was happening because the factory was not following the best procedure to build up the shafts. They were using separate folding reinforcement tape in each shaft component. They were folding each component separately keeping the seam edges open. They were stitching the components folded. And they were folding the open seam edges.

Impactiva solution: we got the factory to stitch together all the shaft components and attach one continuous reinforcement tape on the topline, then fold the edges of all the components continuously in order to achieve a smooth and round topline, including the stitching joints.
