- Realistic / Conventional
- 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.
- Manual cutting processes for leather
Cutting rules, variance of the leather properties on its surface and elongation directions of the footwear pieces.
- Footwear equipments
Functionality of the wide range of equipments and the basic rules of regular maintenance.
- Footwear machinery
Tthe functionality of the wide range of 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 components
Footwear components both for uppers (vamps, quarters, linings, stiffeners, toe puffs etc.) and bottoms (soles, heels, insoles etc.). Ecological concerns and the importance of recycling. Selection of suitable materials and components based on their influence on the footwear style and characteristics, properties and manufacturability. Procedures and methods in chemical and mechanical processing of leather and non-leather materials.
- 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. Quality assurance of footwear production processes and fundamental concepts on quality including footwear quality framework and standards.
- Pattern grading
Know about cutting patterns accurately and grading the patterns to obtain the size series in case of mass production. Know how to mark notches, holes, seam allowances, and other technical specifications. Make adjustments and obtain the final patterns for cutting in order to compensate any identified problems during sampling.
- 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.
- 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 pre-stitching techniques
Apply pre-stitching techniques to footwear and leather goods in order to reduce thickness, to reinforce, to mark the pieces, to decorate or to reinforce their edges or surfaces. Be able to operate various machinery for splitting, skiving, folding, stitch marking, stamping, press punching, perforating, embossing, gluing, uppers pre-forming, crimping etc. Be able to adjust the working parameters of the machinery.
- Create patterns for footwear
Produce the mean form or shell, a two-dimensional representation of the three-dimensional shape of the last. Create scaled patterns for uppers and bottom components by manual methods from the designs.
- Apply 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.
- Perform manual cutting for footwear uppers
Be able to check and complete cutting orders, select leather surfaces, classify cut pieces. manual dexterity, as well as ability for identifying faults and defects on the leather surface are required. A very good visual capacity is also necessary in order to recognise colours, shades and type of finishes. Be able to use the following tools: knife, pattern templates, cutting board and marking needle.
- Apply basic rules of maintenance to leather goods and footwear machinery
Apply basic rules of maintenance and cleanliness on footwear and leather goods production equipment and machines that you operate.
