Shoe Board Lasting
In shoe board lasting, the assembly operation involves stretching the shoe upper over the last. A distinguishing feature of board lasting is the use of a paper fiber board that is either stapled or glued to the bottom of the last. This board provides stability and support to the shoe during the lasting process.
In mass-produced shoes, a lasting machine is often employed to streamline the process. The machine applies hydraulic force to pull the upper tightly over the last while simultaneously injecting hot glue to bond the upper to the board. This combination of pressure and adhesive ensures a secure attachment between the upper and the board.
The lasting process typically starts with lasting the toe area, followed by the heel and then the waist. This sequential approach helps achieve proper shaping and tension distribution throughout the shoe.
Board lasting is commonly used for leather shoes and boots due to their sturdiness and durability requirements. However, it can also be utilized in the production of certain types of sport shoes.
Overall, board lasting, with the incorporation of a fiber board and the use of machinery, offers an efficient and reliable method for attaching the shoe upper to the last, contributing to the overall construction of the footwear.
