Wavy stitching – Case #445

“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: wavy and inconsistent stitching in the central strap, caused by keeping the pressure roller of the sewing machine on this narrow central strap, what gives the sewing operator too little space and no control over the movement of this strap component.

Impactiva solution: we got the factory to perform the stitching placing the pressure roller next to the central strap (on the underlying component) in order to give the operator proper space to do a straight stitching.
