Analysis Of Footwear Gluing Process

Use adhesive to help feet, bottom and outsole combined with the processing technology is called the adhesive technology.

(1) help feet to process.

Its technological process is: pulling out the nails, fixing the nails, trimming the stubble, gluing the feet, leveling the feet, filling the bottom of the heart, processing the adhesive surface, drawing the outer base line.

(2) glue binding process.

After processing, the rubber can be brushed, dried, activated and bottomed out.

Brushing the adhesive.

A. purifying sticky surface.

In general, we use mechanical bristle wheel for dust removal or air blowing with compressed space gas.

B. blending.

The operation of adding different types and proportions of curing agents in adhesives to enhance the adhesion is carried out.

C. brush operation.

In addition to automatic spraying, the rubber brush is commonly used.

Drying and activation of film.

After brushing operation, semi-finished shoes need to go directly into the drying channel for drying and activation.

Its function is to speed up the volatilization of solvents and water in adhesives, shorten processing time and improve adhesive quality.

The degree of drying live goods is generally referred to as touch test, that is, using finger to touch the film, and feel that the adhesive film is sticky and wet, which means "eight minutes dry".

This method is suitable for neoprene, while resin adhesive is suitable when dry.
