Abstract: Wire cloth comprising a woven structure (2) defined by: a weave (3) comprising a plurality of first thread-like elements (3a) made of metallic material; and a warp (4) woven with said weave and comprising a plurality of second thread-like elements (4a) made at least partially of metallic material; said structure (2) further comprising at least one lateral area (5) parallel to said warp (4) and having deformation means (6) for occluding channels (7) defined between the first thread-like elements (3a) at said lateral zone (5).

Abstract: An automatic screen changer device for use on systems and equipments for the manufacturing, processing, recycling and treatment of thermoplastic materials, is placed downstream of an extruder device and includes a frame (12), two opposite side plates or shoulders secured to the frame and provided, respectively, with an inlet opening (18) and a pair of inlet channels (30), with an outlet opening (20) and with a pair of outlet channels (32), the inlet channels allowing a flow and a screening of contaminated molten material in the direction of the outlet channels through a pair of stacked screening units; the device likewise includes movable sealing and locking/unlocking elements of a screening support or band for the screening of the molten material in each screening unit with the latter movable reciprocally with temporary interruption of the flow of molten material through one of the same screening units during the screen change.
