Abstract

Wynalazek dotyczy sposóbu ciągłej produkcji wzmocnionego elastycznego węża, jak również linii produkcyjnej i stanowiska wytłaczania do realizacji sposobu, oraz wzmocnionego elastycznego węża, zwłaszcza ogrodowego, otrzymanego tym sposobem. Sposób obejmuje etapy dostarczania półwyrobu węża zawierającego co najmniej jedną wewnętrzną warstwę i nawiniętą na jej zewnętrzną powierzchnię co najmniej jedną tekstylną wzmacniającą warstwę, i wytłaczanie termoplastycznego materiału polimerowego na półwyrób węża w celu utworzenia pokrywającej warstwy. Etap wytłaczania wykonuje się za pomocą dyszy wytłaczającej (31) mającej otwór środkowy (34) wyznaczający oś przenoszenia (X), mieszczący półwyrób węża, i kanał obwodowy (35) zawierający skośny rurowy odcinek i zasadniczo poziomy rurowy odcinek względem jej wylotu (37). Etap wytłaczania wykonuje się poprzez poddanie otworu środkowego (34) działaniu podciśnienia w celu wyciągnięcia pokrywającej warstwy do bliskiego kontaktu z półwyrobem węża. Grubość wytłoczonej powłoki rurowej wynosi 0,1 mm do 0,35 mm. Ciśnienie bezwzględne w otworze środkowym (34) jest nie mniejsze niż 350 mmHg.The invention relates to a method of continuous production of a reinforced flexible hose, as well as a production line and extrusion station for carrying out the method, and a reinforced flexible hose, especially a garden hose, obtained by this method. The method comprises the steps of providing a hose blank comprising at least one inner layer and at least one textile reinforcing layer wound on its outer surface, and extruding a thermoplastic polymer material onto the hose blank to form a covering layer. The extrusion step is carried out by means of an extrusion nozzle (31) having a central opening (34) defining the transfer axis (X) housing the hose blank and a peripheral channel (35) comprising an oblique tubular section and a substantially horizontal tubular section relative to its outlet (37). The extrusion step is carried out by subjecting the central hole (34) to a vacuum in order to pull the covering layer in close contact with the hose blank. The thickness of the extruded tubular coating is 0.1 mm to 0.35 mm. The absolute pressure in the central hole (34) is not less than 350 mmHg.
