A spinner head provides for the production of melt-spun product. The spinner head includes a base and a cover spaced from the base. A plurality of discrete spaced apart elongate heating elements are positioned between the base and the cover and define a chamber for accommodating feedstock material therein. An elongate generally annular housing having plural circumferentially spaced cylindrical passages extending therethrough is positionable over the heating elements. The housing defines a plurality of circumferentially spaced fins projecting radially inward. Each of the fins has tapered sidewalls which generally converge as the fin extends radially inward. The sidewalls of adjacent fins cooperate to define longitudinal radially-directed slots between the cylindrical passages so as to permit passage of the feedstock material therethrough.
L'invention porte sur une tête de filage servant à la fabrication de produits filés à chaud et comprenant: une base et un couvercle distante de la base; plusieurs éléments chauffants allongés indépendants et séparés placés entre la base et le couvercle et entourant un réservoir de produit alimentaire; une enceinte sensiblement annulaire allongée présentant plusieurs passages cylindriques allongés traversants répartis sur sa circonférence et pouvant se placer sur les éléments chauffants, ainsi que des ailettes effilées réparties sur sa circonférence et se projetant radialement vers l'intérieur. Les parois d'ailettes voisines concourent à former entre les passages cylindriques des fentes longitudinales dirigées radialement permettant le passage du produit alimentaire.
