摘要： A method of manufacturing a film (F1) including cavities and formed from a polymer in which a cavitating agent is dispersed, said method including a step of extruding the polymer through an extrusion die equipped with adjustment actuators for adjusting thickness of the extruded film, and a step of stretching (Str1) the film, as well as establishing a mapping function of the film on the basis of mass-per-unit-area profiles of the film before and after the stretching step, establishing a stretch profile of the film as stretched on the basis of said mapping function and of said transverse mass-per-unit-area profiles, and establishing a characteristic transverse profile that is characteristic of the film on the basis of said stretch profile and of a transverse profile of the concentration by mass of cavitating agent in the film as stretched that makes it possible to take into account the distribution of the cavities in the film; in which method said adjustment actuators are controlled as a function of said characteristic transverse profile.

摘要： A method for the production of an elastic laminate, with the following steps in a production line: coextrudeing a first web of elastic film with at least three layers, with at least two different polymer materials, to feed contemporaneously said coextruded first elastic film web and two second nonwoven webs to a thermal, binding calender, wherein the first elastic film web is arranged between said two second nonwoven webs when entering the calender; wherein said first elastic film web, during the movement from the coextrusion step to the thermal binding step, passes from a melted state, to a solidified and cold state when entering the calender, to join, through spot welding in said calender, said second nonwoven webs with respective opposite outer layers of said first elastic film web, thus producing an intermediate web, to stretch mechanically said intermediate web according to a direction transverse to the same web.

摘要： Systems and methods for forming insulation on magnet wire are provided. An extruder that includes one or more rotating screws may receive a thermoset polymeric material and process the thermoset polymeric material to increase its pressure and temperature. An extrusion crosshead assembly in fluid communication with the extruder may receive the thermoset polymeric material and press extrude the thermoset polymeric material as insulation onto a magnet wire. A curing device may then cure the extruded insulation material.

摘要： Disclosed is an apparatus for the production of a blown tubular film (FT). The apparatus includes an independent device for the localized thickness adjustment at the strips adjacent to the folding edges resulting from the flattening of the tubular film (FT) by means of adjustment elements formed in angular sectors of limited extension symmetrically arranged 180° apart. The independent device for the localized thickness adjustment being a volumetric type device having a rotating ring that performs a rotating adjustment of the flow rate of a cooling air stream which takes into account the angular offset resulting from the operational parameters of the apparatus.

摘要： A method for measuring a degree of cross-linking of a component of elastomeric material obtained as a result of a hot-forming process, includes a preliminary calibration step in which a plurality of samples are provided, made of the same material as the component. The samples have different degrees of cross-linking following respective hot-forming processes conducted for different periods of time. The preliminary calibration step includes providing a measuring device having an electrical circuit, in which a voltage generator is arranged in series with metal contacts configured to selectively receive a sample, and an ammeter, positioning a sample between said metal contacts, providing a predetermined voltage value, and detecting the corresponding current value by means of said ammeter. The aforesaid steps are repeated for each sample so as to obtain a calibration map that associates a given degree of cross-linking of the material constituting said component with each determined value of electrical conductivity.
