What are the manufacturing stages needed to complete a LOWA hiking/trekking boot?
Evaluating the leather: sorting and distribution
Punching out the pieces: uppers, lining, cushioning, reinforcements, etc.
Setup: preparation of all of the individual pieces including stamping, shaving and bevelling (scarfing) to thin the edges and to equalise the strength of all parts, applying colour touch-ups to the cut faces, pressing flat and fusing together the leather pieces and reinforcements.
Sewing: stitching together the pieces
Cementing: gluing in the cushioning pieces
Riveting: fastening the metal parts such as hooks, eyelets and lace loops
Quality control of the uppers and visual inspection (i.e., the boot without the last and before the insole, outsole or midsole are attached)
Preparing uppers, prior to lasting. Pre-treating the upper.
Attaching the insole to the last
Pulling (shaping) the upper over the last: The upper is drawn snugly and shaped over the last, and then the edges of the upper are cemented to the insole.
Shaping and securing the heel area: The rear part of the upper is cemented or tacked to the insole
Roughing out the upper to attach the rand
Wrapping and cementing on the rubber rand
Roughing out the rand and cementing on the sole unit
