    Abstract: A pipe molding apparatus includes a plurality of mold blocks (9) which move along a molding path to form double wall plastic pipe having an outer pipe wall with corrugations which set outside diameter of the pipe and an inner wall around a bore through the pipe. The mold blocks (9) have profiled faces which determine shape of the pipe. The profiled faces are reconfigureable in profile between first depth of the corrugations and diameter of the bore through the pipe without varying external diameter and while maintaining essentially constant wall thickness of the pipe.

    Abstract: A method and apparatus for producing an extruded product includes a machine that cooperates with an extruder. The machine is commonly used as a corrugator and the extruded product is often corrugated piping. The machine has a frame supporting a trackway in a continuous path. A plurality of mold block assemblies travel about the continuous path to form a mold tunnel along a portion of the continuous path. The mold block assemblies include a carriage connected by at least one guide and linear bearings to a pair of mold holders. The mold holders are connected to at least one pair of opposing mold blocks. Guides and directors position the mold block pairs relative to one another while the assemblies travel along the continuous path. As the holders, and thus the mold block halves, are linearly displaceable from one another, the halves may meet to form the mold tunnel and separate to allow removal of the extruded product.

    Abstract translation: 用于生产挤出产品的方法和设备包括与挤出机配合的机器。 该机通常用作瓦楞纸机，挤压产品通常是波纹管。 机器具有在连续路径中支撑轨道的框架。 多个模块组件围绕连续路径行进以沿连续路径的一部分形成模具通道。 模块组件包括通过至少一个引导件和直线轴承连接到一对模具保持器的托架。 模具保持器连接到至少一对相对的模具块。 导向件和导向器将模块对相对于彼此定位，同时组件沿连续路径移动。 由于保持器以及因此的模块半部可以彼此线性地移位，所以半部可以相遇以形成模具通道并分离以允许移除挤出的产品。

    Abstract: A pelletizing die for a pelletizer comprises a base body with holes for melt to pass through; the holes are disposed in rows. Allocated to the holes are wearing-protection inserts, having holes which are in alignment with the holes in the base body. The inserts which are disposed to adjoin each other in a row have a chordal surface where they are turned toward an adjoining insert and are provided with at least one surface of an arcuate segment of a cylinder laterally of the chordal surface.

    Abstract: A method and apparatus for making U-shaped retaining wall members includes a combination of an extrusion die station, a calibration station, a heavy duty puller such as a tire puller and a travelling saw. The calibration station includes a series of calibration blocks which are spaced apart in an increasing fashion and controllably cooled to subject the extruded product exiting the extruding station to a controlled temperature gradient to prevent thermal shock.

    Abstract: An apparatus produces plastic tubes by extrusion with an extruder, a pipehead being attached to the extruder in production direction, having a base material with at least one mandrel and a sleeve, a melt channel between the mandrel and the sleeve, the melt channel shaped to aid flow in production direction at least at the mandrel's end and at the sleeve's end, the mandrel and sleeve being adjustable backwards and forward relatively to one another, the outer surface of the mandrel and/or the inner surface of the sleeve at least partially has a material that allows for a higher sliding quality than the base material. The outer and/or the inner surface (i) has a coating either unvaried, or whose sliding quality constantly improves, or whose sliding quality alternately improves and worsens, in the production direction, or (ii) is partially coated, or (iii) the mandrel and/or sleeve fronts are coated.

    Abstract: An extrusion die with fastener tension adjustment assembly can be formed of a die body that includes a first die body portion and a second die body portion. The extrusion die can have a lip body connected to one of the die body portions using the plurality of fasteners. In one configuration, the fastener tension adjustment assembly has an elongated body operatively connected to each of said plurality of fasteners. The fastener tension adjustment assembly is movable towards and away from the lip body, thereby simultaneously adjusting an amount of force applied to each of said plurality of fasteners. Because the fastener tension adjustment assembly can simultaneously adjust the amount of force on each of the plurality of fasteners, it can eliminate time consuming fastener-by-fastener adjustments on the extrusion die.
