Method and apparatus for pulling polymeric material from an extrusion die as a tubular extrusion uses a pair of mutually-facing endless belts for pulling the extrusion from the extrusion die by frictional contact with the extrusion, the belts being spaced apart from one another for frictional driving passage of the tubular extrusion therebetween, spacing of the belts being continuously adjusted in response to signal from a gauge continuously measuring outer diameter of the tubular extrusion upstream of the belts.

A transparent and heat-resistant polycarbonate (PC) composite and a preparation method thereof. The PC composite is a blend of a PC, a polyarylester (PAR) and an organic salt. The preparation method includes: drying the PC and the PAR each under vacuum at 80-120 C. for 24-48 h; adding the dried PC, the dried PAR and the organic salt into a melt blending device at a mass ratio of (60-90):(40-10):(0.3-3), and performing melt blending at 250-300 C. to obtain a mixture; and discharging the mixture from the melt blending device, and cooling to normal temperature to obtain a PC composite.

A three-dimensional printer is configured to fill interior cavities of a fabricated object with functional or aesthetic materials during fabrication. In general, a number of layers can be fabricated with an infill pattern that leaves void space within an exterior surface of the object. These void spaces can receive a second material such as an epoxy or adhesive that spans multiple layers of the object to increase structural integrity. Similarly, aesthetic materials may be used to add color, opacity, or other desired properties to a fabricated object. The void spaces can also or instead form molds that are filled with a build material to provide a fabricated object.

The invention relates to a method and a device for producing a circular-cylindrical body (4) which consists of a plastic compound and which has at least one helical inner recess that runs in the interior of the body. The method has the following steps: producing a circular-cylindrical body (4), which consists of a plastic compound and which has at least one linear inner recess that runs in the interior of the body, by means of an extrusion molding die (1), discharging the circular-cylindrical body (4) out of the extrusion molding die (1) via a twisting section (7) onto a holding and transporting device (2) which is designed to hold and transport the circular-cylindrical body (4) and which can be rotated about the longitudinal axis of the holding and transporting device, twisting the circular-cylindrical body (4) on the twisting section (7) in order to form the at least one helical inner recess by rotating the holding and transporting device (2) together with the circular-cylindrical body being held and transported in the holding and transporting device, and discharging the circular-cylindrical body (4), which has at least one helical inner recess running in the interior of the body, out of the holding and transporting device (2) onto a storage device (3).

A three-dimensional drawing device can include a housing configured for to be held in user's hand, shaped to allow manipulation of the housing like a pen, and configured to accept a strand of thermoplastic material. The drawing device has a nozzle assembly with an exit nozzle and a motor connected to a gear train that engages the strand such that rotation of the motor causes the feed stock to be extruded out of the exit nozzle to form a three-dimensional object. The motor can be controlled using a variable speed control mechanism or first and second actuators, thereby controlling movement of the strand, for example, to advance or retract the strand relative to the nozzle assembly.

A system for making a tire tread includes an extruder, a roller die having a first axis of rotation, and a conveyor that receives a round strip (or noodle) of green rubber from the extruder and feeds the strip of green rubber to the roller die. The system further includes a drum having a second axis of rotation, wherein the roller die is configured to apply the strip of green rubber to the drum. The system also includes a controller, wherein the controller is configured to control a translation of the roller die in a first direction parallel to the first axis of rotation. The controller is configured to control a roller die rotation speed and a drum rotation speed, and the controller varies at least one of the roller die rotation speed and the drum rotation speed during translation of the roller die.
