    摘要： A method is disclosed for manufacturing connectable or non-connectable elongate porous plastic profiles 12 from substantially continuous randomised extruded plastic strands made of recycled thermoplastics. Current manufacturing processes can manufacture similar products, comprising short partially melted plastic particles melded together forming planks. These planks, however, are inherently friable, easily broken and not readily connectable. These shortcomings are caused by the manufacturing method used, being friction plate agglomeration. This invention utilises an extrusion process, which produces substantially endless random strands of thermoplastic 13 which drop and are welded together to form a porous mass, which is then compressed into boards or planks by pulling the mass through a forming tool 6 and 7. The profile can be adjusted to form edge recesses allowing the planks to be fitted together,for instance to form area coverings, or they can simply be laid end to end to form drainage channels.

    摘要： 本发明公开了一种超薄聚乙烯管道生产设备及生产方法，本申请装置包括冷却喷淋装置、支撑结构、挤出机、定径套、若干滚轮环组件和牵引机，支撑结构的外形分为半梭形前段和管状后段，半梭形前段的头部通过钢绳与挤出机连接；当管材向后牵引时，管材内壁与支撑结构外壁接触并带动支撑结构向后运动，直至支撑结构头部与挤出机相连的钢绳绷紧时，支撑结构刚好位于牵引机的上下履带之间，支撑结构可以给管材提供足够的支撑力，防止管材在牵引过程中变形；滚轮环组件用以对向后牵引的管材外壁提供滚动限位作用，防止管材发生形变。本发明的生产设备可实现SDR100的超薄聚乙烯管道挤出，同时优化整道生产工序，防止管材在定型、冷却、牵引过程中发生形变。

    摘要： A method for producing reels (B) of plastic film (F) by cast extrusion process is described, comprising the steps of: (a) causing the film (F) to flow out from a slit (12) of an extrusion head (10) by adjusting its thickness by means of adjustment means (26); (b) drawing the film (F) exiting the extrusion head (10) by means of an internally cooled roll (14); (c) winding the film (F) coming from the roll (14) by means of a winding unit (16) placed downstream of the roll (14) so as to form reels (B) of film (F), (d) measuring the thickness of the film (F) by means of a thickness measuring device (22) interposed between the roll (14) and the winding unit (16), and (e) controlling the adjustment means (26) to adjust the thickness of the film (F) based on the thickness measurements provided by the thickness measuring device (22). According to the invention, the method further comprises the steps of: (f) measuring a reference quantity of the film reels (B) produced, said reference quantity depending on the thickness of the film (F); (g) comparing the measured value of said reference quantity with a design value of said reference quantity corresponding to the design value of the thickness of the film (F); and (h) if the measured value is different from the design value of said reference quantity, acting on said adjustment means (26) and/or on said thickness measuring device (22) to obtain a thickness of the film (F) corresponding to the desired one.

    摘要： The present invention relates to a very long pipe formed in a single extrusion process from certain types of thermoplastic polymer [for example a polymer from the polyaryletherketone (PAEK) family, such as polyetheretherketone (PEEK)] where such pipes are manufactured in a way that delivers a particularly low occurrence of certain types of defect. Said defects include an area of the pipe wall that has a thickness that is too high or too low vs adesiredspecification or a section of pipe where the outside diameter is too high or too low versus a desired specification. The invention further relates to a process for forming such long polymer pipes.
