Method of making bicycle saddle using sewing or split joined saddle surface vacuum suction moulding

Abstract

A process for preparing the saddle of bicycle from the sewed or spliced saddle top by vacuum moulding includes sewing or slicing saddle top, sticking adhesive sealing belts on its back, hot pressing or coating sealant, fixing it to a mould, vacuumizing to suck it into mould cavity, filling foaming material and foaming.

Description

Technical field: [0001] The invention relates to a method for preparing a bicycle saddle, in particular to a method for preparing a bicycle saddle by using a vacuum suction molding process using a sewn or spliced ​​saddle surface. Background technique: [0002] At present, the bicycle saddles produced by the vacuum-absorbing process are all single-leather saddles. When using the vacuum suction process to produce saddles, the saddle surface must first be fixed on the mold, and the artificial leather surface is absorbed into the cavity of the mold by using the negative pressure generated by the vacuum, and then various types of plastic are injected into the cavity of the mold. Foam molding. Since the saddle surface of artificial leather must be guaranteed to be airtight when using the vacuum forming process, and there are gaps in the sewing line or splicing seam of the saddle surface sewn or spliced, so the current vacuum forming production process cannot make the saddle surf...

Problems solved by technology

However, it has disadvantages such as low working efficiency, easy to change the shape, and the saddle is easy to absorb water and wet the rider's pants in rainy days.
