摘要： A process for blow-molding hollow bodies from thermoplastic synthetic resin wherein, in addition to control to accurately position an extruder thermoplastic melt preform in the blow mold and to maintain a constant weight of the extruded preform, on the program curve which itself is a superimposition of the profile curve of the preform and a base gap determined in accordance with the nozzle gap width through which the preform is extruded, there is superimposed a correction strip which can be varied depending upon material distribution changes as a result, for example, of sag of the preform.

摘要： An extrusion head for blow molding extruded plastic containers, with a ring gap nozzle having a mandrel and a ring-shaped nozzle body having an elastically deformable sleeve, and setting devices for radially deforming the elastic sleeve. The sleeve defines a nozzle gap, the width of which is variable by axially movement of the mandrel and/or of the nozzle body. The geometry of the gap can be changed by deforming the sleeve in the course of extrusion of a hose-like, pre-shaped blank. The sleeve is axially supported in the nozzle body, and/or on the mandrel only on segment-like surfaces.

摘要： The extrusion blow molding of hollow bodies is carried out with a wall thickness program which in addition to varying the gap width over the entire perimeter of the gap in accordance with a first program curve and varying the geometry of the gap in response to a second program curve, automatically enhances a profiling of the preform to increase differences between the thick and thin regions with the variation in geometry when the gap width is greater in a reference value and diminishes the profiling of the preform to decrease such differences when the gap width is less than the reference value.

摘要： The invention sets out a method and apparatus of forming a chime projecting radially outwardly of a blow molded hollow member. The chime is formed immediately after the blow molding of the hollow member by forming a radially outwardly projecting channel-shaped part in the side wall of the hollow member. The surfaces of the channel-shaped part are moved toward each other to form a welded connection at the radially inner end of the channel-shaped part. The movement of the channel-shaped part to form the chime is effected by telescoping slides which move axially at different stroke speeds and at different stroke lengths. The radially inwardly most disposed slide moves farthest and faster so as to produce a rolling movement of the channel-shaped part as the chime is formed. The resulting chime is integrally formed from the material of the hollow member and includes at least an outer wall extending circumferentially around the hollow member and a side wall to which the outer wall is welded at its inner radial end.
摘要翻译：本发明提出了一种形成在吹塑中空构件的径向向外突出的钟声的方法和装置。通过在中空构件的侧壁中形成径向向外突出的通道形部分，立即在中空构件的吹塑之后立即形成钟声。通道形部分的表面彼此相对移动以在通道形部分的径向内端处形成焊接连接。通道形部分形成钟声的运动是通过在不同的行程速度和不同行程长度上轴向移动的伸缩滑块来实现的。径向向内最设置的滑块最远和更快地移动，以便在形成钟形时产生通道形部分的滚动运动。所得到的钟声由中空构件的材料一体地形成，并且至少包括围绕中空构件周向延伸的外壁和在其内径向端部焊接外壁的侧壁。

摘要： An extruder head for extrusion blow-molding plastic containers includes a ring gap nozzle with a mandrel and a ring-shaped nozzle body. An elastically deformable sleeve is arranged on an end of the nozzle outlet side and defines a gap width which can be varied by axial setting movements of the mandrel and/or the nozzle body. The geometry of the nozzle gap can be influenced by radially deforming the sleeve with setting devices during the extrusion of a hose-shaped preformed blank. The sleeve may be moved in a radial direction and is guided on sliding surfaces which support it in upward and downward directions. The sleeve may be in the form of a cylinder or tube. A lower edge of the sleeve shapes a cross-section of a melt stream exiting from the ring gap nozzle.

摘要： A mold has a core surrounded by an outer sleeve which defines with the core an annular axially extending passage. An adjustment element in the form of a ring or sleeve is displaceable in this passage so as to vary the radial dimension of a tubular blank that is extruded from the outlet end of the passage. The adjustment ring or sleeve may be elastically deformable by means of hydraulic cylinders or screws so as to create the desired thickness at the desired location, and may even be displaced during operation of the apparatus so as to vary the thickness of the blank from one region to another in the direction in which it is extruded.

摘要： A method for the extrusion of preforms (1), which exit from a die gap of an extrusion head (4) delimited by a mandrel (2) and a die ring (3), and are widened in a blow mold (5). The width of the die gap is changed during the extrusion of the preforms, by means of a setting movement of the mandrel and/or of the die ring. The cross-sectional geometry of an elastically deformable sleeve (9) disposed on the extrusion head (4) and delimiting the die gap on the circumference side is also changed during the extrusion of the preforms. By means of setting movements of an additional element (10) that is controlled or regulated separately, the melt distribution on the circumference side is changed at least in that section of the preforms (1) that is widened to form an upper barrel end in the blow mold (5). In this connection, the deformation of the sleeve (9) and the setting movements of the additional element (10) are coordinated with one another in such a manner that the upper region of the barrels widened in the blow mold has no deviations in thickness from default values in the circumference direction.
