Plastic flooring having registration system contains: an electronic control unit electrically connected with roller equipment and the registration system, the roller equipment is configured to deliver a substrate, a printing layer, and an abrasion resistance layer toward a rolling device. The rolling device includes a fourth roller set having pressing patterns identical to surface patterns of the printing layer, and the registration system has a first sensor, a tension regulator, and a second sensor. The first sensor is disposed on a delivery path of the printing layer which corresponds to the first sensor and has multiple positioning points. A length between a first positioning point and a second positioning point depends on a perimeter of the fourth roller set so as to form a print unit, and the first sensor is configured to sense the multiple positioning points and to transmit sensed signals to the electronic control unit.

The present invention relates to a molding thickness inspection device, a molding thickness inspection system including the same, and a molding thickness inspection method. The molding thickness inspection system according to an aspect of the present invention includes a molding thickness inspection device in which a plurality of illuminance sensors are installed and which accommodates an inspection target product which is illuminated, and a control device configured to inspect whether a thickness of the inspection target product is abnormal based on illuminance data measured by the plurality of illuminance sensors.

Rheological measurement systems for use with systems including pressurized polymer melts and/or other viscous materials are described. In one embodiment, a rheometer is connected to an associated system with a bent, curved, or bendable tube to permit the rheometer to measure rheological properties in locations where the rheometer could not otherwise be located due to the presence of obstructions. Embodiments including rigid straight tubes for connecting a rheometer to an associated system are also described. In another embodiment, a flow-through rheometer is connected to an industry standard ?-20 thermowell aperture that is typically used for attaching temperature and pressure probes to a vessel containing a viscous material such as an extruder or injection molding system.

A fiber composite laying device for producing a fiber composite scrim for forming a fiber composite component has a laying head which is designed or configured to continuously supply a reinforcement fiber band, a compaction roller which is designed or configured to receive the supplied reinforcement fiber band, lay the band on a laying surface and press the band onto the laying surface at an average compaction pressure, and pressure sensors which are arranged on the compaction roller and are designed or configured to detect a local compaction pressure on the laid reinforcement fiber band.

A method for monitoring a device for supplying temperature control media to a mold of a molding machine, wherein the device has a feed line and a return line between which a temperature control line is arranged, a measuring element arranged in each of the temperature control lines actually to be monitored, and a control element arranged in each temperature control line to be regulated or to be controlled. A pressure drop in the temperature control line is measured, a hydraulic resistance and/or a change in resistance of the temperature control line is calculated based on an a volumetric flow rate measured using the measuring element and based on the measured pressure drop. The degree of opening of the control element is taken into consideration in the calculation of the hydraulic resistance and/or the change in resistance.

An expansion device, including: an installation unit in which a thermally expandable sheet is disposed; an irradiation unit configured to irradiate the thermally expandable sheet placed on the installation unit with light; and a control unit configured to perform processes described below, wherein after an expansion process to expand the thermally expandable sheet by irradiating the thermally expandable sheet placed on the installation unit with light by the irradiation unit, a cooling process to cool the thermally expandable sheet by a predetermined cooling unit while maintaining the state in which the thermally expandable sheet is placed on the installation unit.

A production method of a modeled object includes a fixing step of fixing a thermally expandable sheet onto a tray by entirely or partially fixing a periphery of the thermally expandable sheet placed on the tray by a fixing member; a thermally expanding step of thermally expanding partially the thermally expandable sheet, which is in a state of being fixed onto the tray by the fixing step, by being heated by irradiating the thermally expandable sheet with light by an irradiation unit, while moving the irradiation unit from a first position toward a second position unit; and cooling the thermally expandable sheet, which has been thermally expanded partially by the thermally expanding step, while maintaining the state in which the thermally expandable sheet is fixed onto the tray, while returning the irradiation unit from the second position to the first position.

The demoldability prediction model includes the steps of choosing a mold specimen; choosing a reference material; measuring the force F.sub.0 for demolding the reference material from the mold specimen; determining the force M.sub.0 for demolding the reference material from the control test specimen; selecting a material to be measured; determining the force M for demolding the material from the control test specimen; calculating the ratio of the forces M.sub.0 for demolding the reference material and M for demolding the material from the control test specimen so as to define a coefficient C of material impact; and calculating the force F for demolding the material such that F=CF.sub.0.

A composite layup is formed on a tool and placed on a contoured part. The tool is contoured to substantially match the contour of the part. A set of location data is generated which represents the location of the part in space relative to the tool. An automated manipulator uses the location data to move the tool into proximity to the part and place the contoured layup on the part.

A method for operating a molding machine includes providing dependencies between, in particular unsorted and/or partially circularly interdependent, actions for performing at least one task. The at least one task is or comprises an operation, a startup or shutdown, a maintenance and/or an optimization of a molding process and/or a molding machine and/or a mold. The method further includes sorting the actions based on the dependencies between the actions.
