| 发明名称 | Extrusion die head | ||
| 摘要 | An extrusion die head for the extrusion of hollow or center-filled shapes as well as apparatus comprising the extrusion die head and methods employing the die head. The extrusion die head (10) is for the preparation of a plurality of center-filled products (34) of varying composition wherein each product comprises a first (filling) material and a second (outer) material. The die head comprises at least one tube (22) such that a first material may be extruded through the tube or tubes and a second material may be extruded around the tube or tubes. The location and the number of the tubes may be customized to vary the location and amount of the first material relative to the second material and thereby vary the composition of the center-filled product. The extrusion die head apparatus comprises a sleeve (40) enclosing the die head. In one embodiment a first material is conveyed from one or more first apertures (18) via one or more tubes (22) to one or more second apertures (20) where it is extruded. Simultaneously, a second material is supplied directly to the remaining second apertures (20) where it is extruded. | ||

| 主权项 | 1. An extrusion die head for the preparation of a plurality of centre-filled products of varying composition wherein each product comprises a first material and a second material, said die head comprising at least one tube such that a first material may be extruded through the tube or tubes and a second material may be extruded around the tube or tubes, and a first plate having a plurality of first apertures therein, wherein the location and the number of the tubes may be customised to vary the location and amount of the first material relative to the second material and thereby vary the composition of the centre-filled product; and the customization is achieved via the at least one tube being detachably engaged with the first plate such that a flow path is defined for the first material from the first apertures through the associated at least one tube; and wherein the number of first apertures is greater than the number of tubes. | ||
