Abstract: A motorised roller comprises a central shaft (12) defining a stator (2) arranged axially and exhibiting a plurality of windings, a cylindrical cover (13) defining a rotor (3) arranged about the stator (2) and exhibiting a plurality of permanent magnets, at least a fixing shaft (8) projecting axially from an end (1b) of said motorised roller (1), in order to constrain the motorised roper (1) to an external support structure (7), a connector (9) for connecting the shaft (12) of the stator (2) to the fixing shaft (8), and an elastic joint (14) interposed between the shaft (12) of the stator (2) and the fixing shaft (8) which enables a relative decoupling movement between the fixing shaft (8) and the shaft (12) of the said stator (2).

Abstract: A device for handling and/or performing work operations on objects comprises: at least a first arm (2) comprising a first end (2a) for supporting a tool (3) for moving or working; means for supporting and moving (4) the first arm (2) which comprise at least a first linear electric motor (5), developing on a closed path (P), for moving the first arm (2) along a circular trajectory (91), and at least a second linear electric motor (6), to which the first arm (2) is directly connected, developing in an arched trajectory (92). The first (5) and the second (6) linear electric motors cooperate to move the first arm (2).

Abstract: A device for handling and/or performing work operations on objects comprises a first arm (2) and a second arm (3) each exhibiting a first end (2a, 3a) and a second end (2b, 3b); a support body (4) to which the first arm (2) and the second arm (3) are connected; means for supporting and moving (5) associated to the second ends (2b, 3b) of the first arm (2) and the second arm (3); and at least a first linear electric motor (6a) and at least a second linear electric motor (6b), each associated to a respective arm (2, 3) to produce movement thereof.

Abstract: The invention relates to a switcher for product supply lines, which comprises a support frame (2), a guide channel (8) which is transversally mobile on the support frame (2) with respect to the advancing direction of the products being supplied in inlet. The switcher (1) comprises a telescopic channel (10), located at an end (9) of the guide channel (8), and being slidably mobile with respect thereto. The guide channel (8) is mobile by a support element (6), slidable on respective transversal portions (4, 5) of the support frame (2). The support element (6) is in turn activated by cooperation between a cursor (13), slidable on the support element (6), and a con rod (15), hinged both to the cursor (13) and to a fixed transversal portion (4) of the support frame (2). The guide channel (8) is further provided with a separator device (20) for controlled distancing of the products which are grouped during the input supply stage.
