Process for manufacturing a footwear and footwear parts

Process for producing an outsole or inner sole of a footwear comprising the following steps:

• (a) providing a first form negative mould of the outsole or inner sole comprising of at least one formed plastic sheet as obtained by thermoforming using a first master mould corresponding with the shape of a first side of the outsole or inner sole,
• (b) adding a liquid curable composition to the first form negative mould, wherein the liquid curable composition is a cold pour composition, and
• (c) solidifying the curable composition wherein a solidified outsole or inner sole is obtained and wherein in step (c) the solidified outsole or inner sole as obtained is removed from the first form negative mould,
• wherein the formed plastic sheet of the first form negative mould is obtained by thermoforming using a thermoforming machine comprising of a thermoforming station, a filling station and a cutting station in a continuous process,
• wherein in the thermoforming station step (a) is performed by preparing numerous first form negative moulds in a continuous process starting from a roll of sheet or from an extruder providing a sheet thereby obtaining a continuous sheet of interconnected first form negative moulds,
• wherein in the filling station step (b) is performed by adding the liquid curable composition to the first form negative moulds as prepared in the thermoforming station thereby causing the continuous sheet of interconnected first form negative moulds to contain the curable composition,
• wherein in the cutting station the continuous sheet of interconnected first form negative moulds containing the curable composition is cut into single first form negative moulds containing the curable composition or groups of first form negative moulds containing the curable composition, and
• wherein step (c) is performed by storing the single first form negative moulds containing the curable composition or the groups of first form negative moulds containing the curable composition as obtained in the cutting station elsewhere from the thermoforming machine.
