The present invention relates to a method for changing material in an extrusion device comprising at least two supply devices for supplying feedstock for an extruder, comprising the following steps: identifying a change request for changing material in an extrusion device, predetermining a production stability for a time after the material of at least one supply device has been changed, comparing the predetermined production stability to a threshold value of stability, changing the material in at least one supply device depending on the result of comparison.

An air cleaning system has a field charger comprising a plurality of bars comprising a conductive inner core and a non-conductive overmold, and a plurality of pins attached to the bars and extending out of the non-conductive overmold. The conductive inner core is molded over the plurality of pins, conductively connecting the pins, and the non-conductive overmold is molded over the conductive inner core. A method of manufacturing the field charger includes placing a plurality of metal pins in a mold, placing contact points in the mold, molding a conductive resin over at least a portion of the plurality of pins and contact points, molding an insulating resin over the inner core, plurality of pins, and contact points, wherein at least a portion of the pins and contact points extend from the non-conductive overmold, and mounting an earthplate to the conductive overmold.

A dosage device for extruding a monocomponent or a bicomponent polymeric product, particularly for an automatic machine for forming a spacer frame, includes a first dosage assembly and a separate second dosage assembly for the dosage and feeding of the product, which can be activated, in a first feeding step and in a third feeding step, alternately so that one of them provides continuity of flow to an extrusion nozzle while the other one is in the reloading step. The first and second dosage assemblies are activated, in a second swapping step that is intermediate with respect to the first and third feeding steps, simultaneously and jointly, one of them having a flow-rate ramp that passes from the steady-state value to zero and the other one complementarily having a flow-rate ramp that passes from zero to the steady-state value.

Distribution apparatus (1) for distributing sliding solid material, comprising at least one first collector (10) comprising a first plurality of first ports (11) connected to one or more departure stations, at least one second collector (20) comprising a second plurality of second ports (21) connected to one or more arrival stations, at least one central connection (30) which is interposed between the first collector and the second collector, wherein each of the ports is connected to a respective pipe (13)(23) for transporting the sliding solid material from the first collector to the central connection or from the central connection to the second collector, and wherein each of the pipes can be controlled in terms of movement between an operating position and a rest position by means of rotation of at least one portion of the pipe.
