MELT-RECEIVING DEVICE AND MELT-RECEIVING METHOD FOR FORMING POLYMER PREFORMS
The invention relates to a melt-receiving device for an extrusion device (1). The melt-receiving device (2) has a hollow guide (13), in the cavity (14) of which a melt passage (SP) is formed. Arranged in the cavity (14) is an agitator (15), which tapers in the direction of flow (FR) of the polymer melt. The melt passage (SP) has on the input side of the receiving device, between the guide (13) and the agitator (15), a cross section (Q1) in the form of an annular gap and has on the output side of the receiving device a full-area cross section (Q2). The agitator (15) has a tip (17) arranged eccentrically in relation to the axis of rotation (16). The agitator (15) also has in the direction of flow (FR) a first portion (98, 98'), which has the form of a truncated cone or truncated prism, and a second portion (99, 99'), which has the form of a pointed cone or a pointed pyramid, wherein the tip of the cone or the tip of the pyramid is the tip (17) of the agitator (15, 15'). As an alternative or in addition, the inner contour of the hollow guide (13) has in the direction of flow (FR) firstly a further cylindrical portion (102), in which a first part of the agitator (15) is arranged, and following that a funnel portion, in which at least one further part of the agitator (15) is arranged.
The present invention relates to an extruder unit (4) for producing preforms (64) having a tubular wall made of a plastic melt, and to an associated extrusion process. The extruder unit (4) has a receptacle for an interchangeable output tool (10). It also comprises at least two different and alternately usable profiling devices (9). These profiling devices (9) have outlet-side fastening structures (46, 47), which match across the different profiling devices (9) and form the receptacle for the interchangeable output tool (10), such that the profiling devices (9) are alternately connectable to the same output tool (10). In this way, each output tool, depending on the customer's wishes, can be operated with different profiling devcies (9), in particular in order to carry out profiling by mandrel-body movement or profiling by nozzle-body movement.

EXTRUSION TECHNIQUE FOR FORMING POLYMER PREFORMS, AND TUBE-FORMING TECHNIQUE
The invention relates to a tube-forming device for an extruder unit (4) or an extrusion device (1) and a tube-forming process. The tube-forming device (8) comprises at least one shaping sleeve (21a, 21b, 21c), which is designed to shape a supplied stream of polymer melt from a substantially strand-like cross section (QS) into a tubular cross section (QT). The shaping sleeve (21a, 21b, 21c) has a guiding passage (23) embedded in the sleeve wall (22), such that the guiding passage (23) is a cavity which lies within the sleeve wall (22) and, in the radial direction of the shaping sleeve (21a, 21b, 21c), is enclosed in a sealed manner with respect to the outer surfaces.
The invention relates to an assembly comprising a closing unit (1) for a blow-moulding machine having a first and second mould carrier (5), and comprising a blow-moulding tool which is arranged on the closing unit (1) and which has two tool halves, wherein a mould lower part of each tool half (2, 3) is movable back and forth with respect to the mould upper part of each tool half (2, 3) in a second direction of movement (18), which is different from a first direction of movement (17), between an open state and a closed state by means of at least one first and at least one second actuator, and, in the closed state of the two tool halves, the blow-moulding tool delimits a mould cavity with undercuts when the two mould lower parts are likewise in the closed state. In order to develop the assembly consisting of closing unit (1) and blow-moulding tool to the effect that the mould clamping region of the blow-moulding tool is not restricted by the actuators and at the same time the costs for blow-moulding tools are reduced and the change of the blow-moulding tool is simplified, it is proposed that the actuators, such as for example hydraulic cylinders, are not arranged on the blow-moulding tool itself as was hitherto the case, but on the closing unit (1), and are configured such that they can be coupled to the mould lower part.
The invention relates to a melt distributor 1 having a plurality of trouser-like melt passages (5.1, 5.2, 5.3) for redirecting and distributing melt flows from a thermoplastic plastic. The melt distributor can be connected to a multiple extrusion head for producing multi-layer preforms. According to the invention, the branched junction (8) is designed as a chamfered y-shaped conduit branch, and at least the branched junction (8) between a supply passage part (6) and the discharging passage parts (7.1, 7.2) of the trouser-like melt passage follows a continuously bent curve, the curvature of which is not equal to zero. The chamfered and continuously bent design of the branched junction (8) contributes to shorter flow paths and avoids the formation of dead zones.

The method comprises extruding an approximately tube-shaped preform (2), dividing the melt flow within the extrusion head or separating the extrudate exiting or already exited from the extrusion head, such that a preform having an approximately C-shaped cross section is obtained, forming the preform into a hollow part within a multipart blow molding tool (8) using differential pressure, wherein an expansion and partial preforming of the preform first takes place with the blow molding tool partially closed, then in a further step at least one insert (18) is inserted into the interior of the partially preformed article between the not completely closed blow molding tool and through the open side of the preform, and in a further step the blow molding tool is completely closed, wherein the article is completely formed, forming at least one at least partially circumferential pinch-off seam.

The invention relates to a screw (3) for a screw extruder (1) used for plasticizing and/or conveying thermoplastic materials. Said extruder screw (1) comprises at least one extruder cylinder (2), a material inlet, and at least one extrudate outlet (10) at the end of the extruder cylinder (2) facing away from the material inlet. The extruder screw (3) further comprises a screw thread (8) and forms at least one feeding zone (12) and at least one conveying and mixing zone (13) in which means are provided for shearing the extrudate. The extruder screw (3) according to the invention is characterized in that at least one shearing web (14) is provided as a means for shearing the extrudate, said shearing web (14) extending along the circumference of the extruder screw (3) along more than half the length of the extruder screw (3) and being designed like a thread that runs against the direction of the screw thread (8).
