The present invention relates to a method for rehabilitating lines, in particular sewers, shafts or the like, a curing device being activated or having been activated for curing the curable and/or curing ply, and an advancement of the curing device in the lining sleeve and in particular the power output of the curing device being controlled in an open-loop or closed-loop manner in dependence on the temperature sensed by the temperature measuring device on the outer side of the curable ply.

A three-dimensional image forming system according to the present invention includes a conveyance path along which a heat-expandable sheet is conveyed, a heating unit which heats the heat-expandable sheet by irradiating the heat-expandable sheet with light, a detection sensor which detects that the rear end of the heat-expandable sheet comes close to the heating unit by the conveyance of the heat-expandable sheet along the conveyance path, and a control unit which increases the conveying speed of the heat-expandable sheet whose rear end is detected when the detection sensor detects that the rear end of the heat-expandable sheet comes close to the heating unit.

A method for reconditioning a rollable wheel includes coupling a polymeric wheel to a reconditioning system, the polymeric wheel having an outer surface including an abraded area, the abraded area having a first average surface roughness, and applying heat to the abraded area of the outer surface with one or more heater of the reconditioning system, such that a substantial portion of the abraded area is transformed to have a second average surface roughness, the second average surface roughness less than the first average surface roughness.

A three-dimensional image forming system according to the present invention includes a conveying unit which conveys a heat-expandable sheet along a conveyance path, a heating unit which heats the heat-expandable sheet by irradiating the heat-expandable sheet with light, and a control unit which preheats the surroundings of the heating unit to a previously determined preheat temperature and then causes the conveying unit to convey the heat-expandable sheet.

The present invention relates to an apparatus and a method for the production of a particle foam part. The apparatus has a mold 2 with a mold cavity 3, a steam generator 12 to generate steam for feeding into the mold cavity for the thermoplastic welding into a particle foam part of foam particles present in the mold cavity 3, a feed pipe 10, 11 for the feeding of steam to the mold, wherein a controllable steam valve 13, 14 is provided in the feed pipe, and a pressure sensor 15, 16 is located in the area between the steam valve and the mold, in order to measure the pressure of the supplied steam. A control device 23 controls pressure over time according to to a predetermined profile, wherein the profile has a ramp, in order to increase pressure gradually within a predetermined period of time from an initial value to an end value.

In a conventional laminated gasket production method, when a product of a laminated gasket is demolded from a mold, the product is rubbed against the mold and, therefore, minute scratches are formed on a surface of the laminated gasket. These minute scratches are liable to prevent reliable sealing of a liquid drug. The present invention is a method for producing a gasket to be used for a medical syringe and is characterized by including the steps of: preparing a gasket molding mold; molding a gasket having a circumferential surface portion in the mold with the gasket being laminated with a lamination film; and demolding the gasket from the mold, and then forming a groove only in the lamination film circumferentially of the circumferential surface portion of the gasket.
