An apparatus for non-contact monitoring of travelling objects being produced in an unguided linear process comprising: a toroidal structure with an open aperture defining a measuring zone, a source of radiation configured by a plurality of radiation devices circumferentially disposed within the measuring zone whereby the radiation source emits rays that generate a planar screen of radiation across the object circumferentially to envelop the object, a plurality of circumferentially disposed recording devices for receiving radiation from the radiation devices following interception of the rays by the objects, and analysis means for analyzing imaging information of the emitted radiation recorded by the recording devices thereby to provide a measure of the physical characteristics of the object.

A method and device for producing metal wire by sheathing a wire with an elastomer compound coming from an extruder is described herein. The aspects disclosed herein may include a feed canal for feeding a sheathing die, through which the wire is made to pass at a pre-established nominal speed. Various temperatures are controlled during the method based on a variety of parameters such as the measured speed at which the wire is moving is other than the nominal speed.

The claimed material relates to a silicate fiber and polymer composite having enhanced modulus, viscoelastic and rheological properties.

A method is disclosed for determining at least one geometric parameter of an object comprising a molten component. The method includes determining a relationship between a refractive index of the object and a shrinkage occurring during a solidification of the object. The refractive index and at least one geometric parameter of the object comprising the molten component is determined using a measuring apparatus. At least one geometric parameter of the solidified object from the refractive index and the at least one geometric parameter of the object comprising the molten component is determined using the measuring apparatus and taking into account the determined relationship between the refractive index of the object and the shrinkage occurring during the solidification of the object.

An extrusion device includes a cylinder, a raw material feed port, a screw incorporated in cylinder, a die disposed at one end of the cylinder, and adjustment mechanisms. Raw material feed port supplies raw materials including resin into cylinder. Screw is able to melt the raw materials through kneading. Die includes a plurality of through-holes for ejecting strands made of molten resin supplied from cylinder. Adjustment mechanisms individually adjust ejection amounts of the strands ejected from the plurality of through-holes.

A device that recycles thermoplastics for producing a filament for fused deposition modelling devices (FDM) and respective operating method is provided. The crushed thermoplastic is introduced into the hopper, pushed by a screw, driven by the motor, inside the barrel, whose axial force is sustained by the axial bearing. The thermoplastic is melted with the assistance of electrical heating resistors and passes through a degassing zone connected to the vacuum pump. The thermoplastic is forced through the die, being cooled on a cooling tray having a water circulation system. The diameter of the filament is controlled by the puller based on the data obtained in the measurement system of the filament diameter. A microcontroller controls the entire process.

An extrusion apparatus to sheathe wires, semi-finished products for cables, or stranded wires. The extrusion apparatus includes an extrusion head and a motorized adjustment device. The extrusion head includes a molding die and a semi-finished product guide having an aperture. The semi-finished product guide and the molding die are arranged with respect to each other so that a molding compound can be formed into an extruded molded product through the aperture of the semi-finished product guide via the molding die. The motorized adjustment device is moved by an actuating signal. The motorized adjustment device is assigned to the semi-finished produce guide and/or to the molding die so that the semi-finished product guide and the molding die can be aligned with respect to each other by moving the motorized adjustment device via applying the actuating signal.

An assembly for measuring wear of a barrel and feedscrew combination, wherein the barrel has a longitudinally extending feedscrew disposed therein and a radially extending measuring aperture formed in a wall thereof, includes a measuring probe having a proximity detecting sensor, a barrel plug for removable insertion into the measuring aperture, and a measuring fixture. The barrel plug is configured to undergo wear in an axial direction thereof while inserted into the measuring aperture. The measuring probe and the barrel plug are installed into the measuring fixture for determining wear of the barrel plug in the axial direction thereof. The measuring probe is further configured for removable insertion into the measuring aperture for measuring wear of a flight of the feedscrew. A spacer and rotational tool cooperate with the measuring probe when installing the measuring probe in the measuring aperture.

A method for measuring a tubular strand exiting from an extrusion device comprises directing electromagnetic radiation from an inside of the tubular strand to an inner side of a tubular strand. The electromagnet radiation is radiated from at least one radiation source within a frequency range from 1 GHz to 6000 GHz. The electromagnetic radiation is reflected off of the tubular strand and received by at least one radiation receiver. A value for at least one of a diameter, a wall thickness, and a deviation in shape of the tubular strand is determined from the electromagnetic radiation received by at least one radiation receiver.
