Description

Descrizione del Brevetto per Invenzione Industriale dal titolo: Description of the Patent for Industrial Invention entitled:

"Procedimento, in iniezione diretta, per ottenere suole di calzature dalla colorazione striata" "Process, in direct injection, to obtain shoe soles with a streaked color"

DESCRIZIONE PROVVISORIA PROVISIONAL DESCRIPTION

Il trovato ha per oggetto un procedimento per ottenere suole di calzature in TR o PVC, dalla colorazione striata. The invention relates to a process for obtaining shoe soles in TR or PVC, with a striped color.

Come è noto, un metodo per la produzione di suole, in materiale plastico, è quello mediante iniezione di PVC, TR o altro materiale idoneo in appositi stampi i quali possono contenere o meno la tomaia. As is known, a method for producing soles in plastic material is by injecting PVC, TR or other suitable material into suitable molds which may or may not contain the upper.

Scopo della presente invenzione è quello di fornire un procedimento realizzabile mediante iniettori tipo Lorenzin<®>allo scopo di ottenere suole di calzature sia da applicare successivamente alla tomaia, sia di rettamente iniettate sulla tomai dalla colorazione striata. The object of the present invention is to provide a process which can be carried out by means of injectors of the Lorenzin <®> type in order to obtain shoe soles both to be subsequently applied to the upper and directly injected onto the torso with a streaked color.

Questi ed altri scopi come meglio appariranno dalla descrizione che segue, sono raggiunti dal procedimento di cui alla presente invenzione, le cui principali fasi sono descritte nel seguito in un'esecuzione preferita non limitativa di ulteriori sviluppi neN'ambito del brevetto, con l'ausilio della tavola di disegni allegata che illustra la seguente figura: These and other objects, as will become clearer from the following description, are achieved by the process of the present invention, the main steps of which are described below in a preferred, non-limiting embodiment of further developments in the context of the patent, with the aid of of the attached drawing table illustrating the following figure:

figura 1 : una vista schematica delle principali fasi del procedimento; Figure 1: a schematic view of the main steps of the process;

Come visibile dalla figura 1, il procedimento prevede, preliminarmente, l'introduzione di due colorazioni distinte di granuli di TR o PVD 1 e 2 all'interno di un miscelatore 3 e, da quest'ultimo, attraverso una tramoggia 4, all'interno di un cilindro riscaldato 5 nel quale avviene l'omogeneizzazione della materia plastica la quale, spinta da una vite senza fine 6, è compressa all'interno della testa dell'estrusore 7 e, da quest'ultima iniettata all'interno dello stampo S. As can be seen from Figure 1, the procedure provides, preliminarily, the introduction of two distinct colors of TR or PVD granules 1 and 2 inside a mixer 3 and, from the latter, through a hopper 4, inside of a heated cylinder 5 in which the homogenization of the plastic material takes place which, pushed by a worm screw 6, is compressed inside the extruder head 7 and, by the latter injected into the mold S.

Claims (3)

Procedimento di cui a rivendicazione 1 caratterizzato dal fatto che il materiale plastico utilizzato è PVC o TR. 2. Process according to claim 1 characterized in that the plastic material used is PVC or TR. 3. Procedimento di cui a rivendicazioni precedenti caratterizzato dal fatto che la lunghezza ottimale della vite senza fine (6) è di circa 70 cm.3. Process according to the preceding claims characterized in that the optimal length of the worm screw (6) is about 70 cm.
