assembling processes and techniques for california footwear construction
Technology, equipment, machines and tools for assembling california footwear construction type.
Lasting machine operators pull the forepart, the waist and the seat of the upper over the last using specific machines with the aim of obtaining the final shape of the footwear model. They start by placing the toe in the machine, stretching the edges of the upper over the last, and pressing the seat. They then flatten the wiped edges and cut excess box toe and lining, and use stitching or cementing to fix the shape.

The functionality of the wide range of footwear machines, and the basic rules of regular maintenance.
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.
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.
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.

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 basic rules of maintenance and cleanliness on footwear and leather goods production equipment and machines that you operate.
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.
Adjust and establish the machine technical operating parameters for cutting footwear and leather goods. Check and select the cutting dies, classification of the cut pieces against cutting restrictions, specifications and quality requirements. Check and complete the cutting orders. Perform simple procedures for maintenance of machines.
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.
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.

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.
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.
Produce technical specifications such as drawings, cards, and sheets for the stages of the production of footwear and leather goods. Analyse the technical sheets, defining the working methods. List the operation sequences and distribute the work for the manufacturing of each model.
Check and complete cutting orders, select leather surfaces and classify cut pieces. Identify faults and defects on the leather surface. Recognise colours, shades and type of finishes. Use the following tools: knife, pattern templates, cutting board and marking needle.
Work with the equipment's software. Digitise and mark the leather areas with faults in order to avoid them. Establish nesting and cutting restrictions for each pattern. Pick up, sort, upload patterns, check and complete cutting orders. Adjust the machines and equipment parameters and perform simple procedures for maintenance.
