Abrégé

The device for overlapping, crossing and transferring textile fibres comprises: a first conveyor belt (T1) for transporting an input layer of textile fibres; a setting- out device (10) for receiving the textile fibres from the first conveyor belt (T1) and depositing them on a second conveyor belt (T2). The setting-out device (10) is susceptible of moving in a reciprocating motion along a direction (x). The second conveyor belt (T2) is adapted to move the textile fibres along a direction (y), belonging to a plane perpendicular to the direction (x), in a forward- backward reciprocating motion, wherein, in the total motion, the forward component is much greater than the backward component, for the purpose of producing a flow of overlapped and crossed textile fibres. The device further comprises a final transportation system for carrying away the flow of textile fibres previously overlapped and crossed. The invention also relates to an innovative process for overlapping and crossing textile fibres, which can conveniently be included in a carding process.

The system (10) comprises: - a conveyor apparatus (12) configured for receiving and transferring loose fibers or fiber agglomerates and/or a fiber mattress (M); - at least one taker-in cylinder (14a, 14b) cooperating with said conveyor apparatus (12) for taking and directing said fiber mattress (M); and - a feeder cylinder (16) cooperating with said at least one taker-in cylinder (14a, 14b), so as to take a quantity of fibers coming from said mattress (M) provided by said taker-in cylinder (14a, 14b) and direct said quantity of fibers towards a swift (T) of a carding machine (C) and/or any fiber or card breaking machine. The system (10) further comprises an air generator device (18) located between said at least one taker-in cylinder (14a, 14b) and said feeder cylinder (16); said device (18) being configured for creating an air flow and directing it towards said feeder cylinder (16) in proximity to the region where said at least one taker-in cylinder (14a) and said feeder cylinder (16) cooperate, thereby promoting a continuous, regular and constant transfer of said quantity of fibers.

The rubbing system for making roves comprises a plurality of pairs of sleeves (1, 2, 3, 4); each pair of sleeves having two sleeves (11, 12; 21, 22; 31, 32; 41, 42) arranged parallel to and substantially in contact with each other, wherein each sleeve (11, 12; 21, 22; 31, 32; 41, 42) is susceptible of making a reciprocating motion, along its respective axis, in phase opposition to the other sleeve (11, 12; 21, 22; 31, 32; 41, 42), so as to compact fibres passing through said pair of sleeves (1, 2, 3, 4) in order to make a rove. The motion of each pair of sleeves (1, 2, 3, 4) is controlled by a pulley (13, 23, 33, 43), to which a pair of connecting rods (14, 15) are pivoted, each connecting rod (14, 15) being connected to a respective sleeve (11, 12; 21, 22; 31, 32; 41, 42) of said pairs of sleeves (1, 2, 3, 4). The rubbing system further comprises a drive shaft (20) for rotating the pulleys (13, 23, 33, 43); and an adjustable transmission system for transmitting the motion from the drive shaft (20) to the pulleys (13, 23, 33, 43), and such as to allow the timing of the reversal of the reciprocating motion of each pair of sleeves (1, 2, 3, 4) to be adjusted independently of the other pairs of sleeves.
