Process for decoration and stiffening of a shell of a sport shoe

摘要

The procedure consists of preparing an insert (12) made from three layers and placing it inside a mould with a core and matrix. With the mould closed a second thermoplastic material is injected so that it at least partially covers the insert placed against the wall of the matrix or the core. The reinforcing/decorative component is fixed to the collar (4) of the boot's thermoplastic upper. The procedure comprises: (1) preparing an insert (12) made from three layers - a thermoplastic transparent film layer, a decorative fibre layer and an adhesive film layer; and (2) placing it inside a mould with a core and matrix. With the mould closed a second thermoplastic material is injected into it so that it at least partially covers the insert placed against the wall of the matrix or the core. The reinforcing/decorative component is fixed to the collar (4) of a winter sports boot's thermoplastic upper. An independent claim is also included for a moulded plastic insert that goes inside the boot to seal holes in the surface of the upper.
