摘要:
A shaft support member of at least one (12) of a pair of kneading rolls (11, 12) opposing each other with a very small gap between them and forming a valley portion, in which a resin charged from above stays, is connected to a driving source which changes a shaft gap, and a pair of weir plates (15b) having a shape substantially in conformity with the shape of the valley portion and adjacent to the kneading rolls (11, 12) without coming into contact with them are connected to a moving driving source in the axial direction of the kneading rolls (11, 12) while being spaced apart by a substantial effective width of the kneading rolls (11, 12). A sheet frame supply source supplies sheet frames (40) one by one toward the valley portion. Conveyor means (57, 58) for an inspection sheet is disposed at a discharge position of the inspection sheet, which is formed by bonding a resin sheet (37) kneaded and formed by a pair of kneading rolls (11, 12) and bonded to the sheet frame (40), and a table (59) for the inspection sheet and an imaging apparatus including a light source (64) and a video camera (65) are successively disposed downstream of the conveyor means (57, 58).

Lors de la fabrication et de la transformation de materiaux PVC les dechets qui en resultent sont traites dans un laminoir compose de deux cylindres rotatifs (6, 7) tournant en sens inverse et avec des vitesses de rotation differentes, Les cylindres (6, 7) qui ne peuvent etre chauffes directement seront prechauffes a l'aide de corps de chauffe amovibles (16, 17) avec du courant bon marche durant la nuit Lors du fonctionnement leur temperature sera amenee par frottement et pression jusqu'au point de fusion du materiau PVC Apres qu'une partie du chargement est transformee en une masse ayant une cohesion toute la charge est modelee pour prendre la forme d'un tapis et deposee sous forme d'un rouleau sur les cylindres. Le materiau fondant au contact avec les cylindres forme sur le pourtour du cylindre le plus rapide (7) une feuille qui est enlevee refroidie et enroulee.

A mixer machine (1) comprising a mixing chamber (1a), housing at least two counter-rotating rotors, into which materials to be mixed are pre-established in loaded proportions, said chamber having discharging means (1b) of the mixture at the bottom and a loading throat (1c) at the top into which a plugging and pressing plunger (10) runs, a system of hydraulic pistons (11, 12), lifting said plunger (10) off the loading throat (1c) for loading the materials to be mixed and lowering back the plunger (10) into said throat (1c) to prevent extruding of the mixture and to bear on the mixture, has the thrust block (16) connected to and moved up and down by said hydraulic pistons, defining at the bottom a chamber of a pneumatic cylinder, whose piston (17) is connected to the stem (15) of said plunger (10), sealingly passing through a hole of said thrust plate (16). A pneumatic circuit controls the pressing and/or the floating of said plunger (10) on the mixture and resiliently absorbs thrusts transmitted to the plunger (10) by the materials being mixed.

There is provided a preferred process for continuous mill mixing which comprises: (i) blending a gas-phase produced elastomer and one or more other compounding ingredients in a dry blender (distributive mixing), (ii) feeding the blend to an open roll mill for compounding into sheets or strips (dispersive mixing). A vulcanizing system can be introduced in either the dry blending (i) or mill mixing compounding (ii) step, but is preferably introduced during dry blending.
