footwear machinery
The functionality of the wide range of footwear machines, and the basic rules of regular maintenance.
footwear manufacturing technology
Footwear processes technology and machinery involved. The footwear manufacturing starts in the cutting/clicking room , cutting the uppers and bottom components. The upper components are joined together in the closing room by following a precise order of specific operations: skiving, folding, sewing etc. The closed upper, the insole and other bottom components are brought together in the assembling room, where the main operations are lasting and soling. The process ends with finishing operations in the finishing and packing room.
footwear materials
The characteristics, components, advantages and limitations of a wide range of materials used in footwear production: leather, leather substitutes (synthetics or artificial materials), textile, plastic, rubber etc.
footwear quality
Quality specifications of materials, processes and final products, the most common defects in footwear, quick tests procedures, laboratory tests procedures and standards, adequate equipment for quality checks.

5 competencesapply assembling techniques for cemented footwear construction
Be able to pull the uppers over the last and fix the lasting allowance on insole, manually or by special machines for forepart lasting, waist lasting, and seat lasting. Apart from the main group of lasting operations, the responsibilities of those assembling footwear cemented types may include the following: bottom cementing and sole cementing, heat setting, sole attaching and pressing, chilling, brushing and polishing, last slipping (before or after finishing operations) and heel attaching etc.
apply footwear bottoms pre-assembling techniques
Split, scour surfaces, reduce sole edges, rough, brush, apply primings, halogenate the soles, degrease etc. Use both manual dexterity and machinery. When using machines, adjust their working parameters.
apply footwear finishing techniques
Apply various chemical and mechanical finishing procedures to footwear by performing manual or machine operations, with or without chemicals, such as heel and sole roughing, dying, bottom polishing, cold or hot wax burnishing, cleaning, removing tacks, inserting socks, hot air treeing for removing wrinkles, and cream, spray or antique dressing. Work both manually and use the equipment and machines, and adjust working parameters.
apply footwear uppers pre-assembling techniques
Prepare lasts and uppers, attach insole, insert stiffener and toe puffs, mould the upper on back part, and condition the uppers before lasting. Perform the above-mentioned operations both manually or by using machines. In case of using machines, adjust working parameters.
apply stitching techniques
Apply footwear and leather goods stitching techniques using the appropriate machines, needles, threads and other tools in order to obtain the required model and to comply with the sewing technical specifications.
