20230049211 · 2023-02-16 · ·

The present application discloses a molding process for shoes with inner lining, comprising: placing a molding inner core sleeved with an inner lining in a combined external mold being preset with a semi-molded shell; performing a mold-closing action to make the semi-molded shell in the first external mold and the second external mold attach to the inner lining, respectively; and heating to vulcanize the semi-molded shell, and combining with the inner lining to produce a shoe with inner lining.

Structure and procedure for making a shoe with knitted upper
12239186 · 2025-03-04 · ·

A procedure for making a shoe including steps of weaving/construction of an upper, forming the upper in which two previously constructed stockings are a tube that is closed on one side while the other end of the tube remains open, subjecting the upper to a steam jet that dampens and softens a thermosetting polymer yarn, and passing the upper through a high-temperature kiln. Construction of the sole entails inserting the upper into a shoe-tree of a mould, positioning the shoe-tree with the upper and closure between two rings of the mould for polyurethane injection. Because of the presence of the arch structure a barrier that limits the passage thereof to the inner part of the upper, with filling of the mould, passage of predetermined quantities of polyurethane only through the slots of the arch structure permitting joint points to be created between the sole and upper and with the inner.
