Facility (1) for producing mineral wool, comprising at least one supply device (4) for supplying mineral fibres (3) and a fibre-distribution station (2) comprising a conveyor belt (14) which can move in a longitudinal direction and on which the mineral fibres (3) can be received so as to form a mineral fibre mat (15), characterised in that the fibre distribution station comprises a roller table (12) arranged on the passage of the mineral fibres (3) that are intended to fall by gravity onto the conveyor belt (14), wherein each roller (13) can be driven in rotation about a transverse axis of rotation, the rollers (13) being configured to dispose the mineral fibres (3) uniformly through the thickness of the fibre mat (15) formed on the conveyor belt (14).

A cross-laying machine includes a feed conveyor belt (1') that introduces a fiber web, particularly a nonwoven web, into an input carriage (4') or collector having a reciprocating motion, in which the fiber web is tumbled, particularly 180°, to advance via a rear conveyor belt (6') to a laying carriage (3'), which moves in a transverse reciprocating manner relative to the direction of movement of an output platform, such that the web is laid on an output platform (2') to obtain a roll, characterized in that the feed conveyor belt (1') is arranged to convey the web until the web is tumbled in the input carriage (4'), and such that it clamps the web between the rear conveyor belt (6') before, during and after the web is tumbled, particularly until the laying carriage (3').

Methods, apparatuses, and systems for forming a random fiber web using a pneumatic fiber transport system are disclosed. In one embodiment, a method can optionally include providing a plurality of movable devices including a lickerin configured to remove a plurality of fibers from a mat of fibers transported by a conveyor to a vicinity of the lickerin, causing the plurality of fibers to be dislodged from the lickerin at a dislodgement location within the system, communicating a gas source to entrain the plurality of fibers with the gas source after dislodgement, and collecting the plurality of fibers from the gas source to form the random fiber web.

The application discloses a biodegradable fabric production device and relates to the technical field of biodegradable fabric production.The device comprises a base body, a fixed block and a sliding block two, the inner bottom of the base body is provided with a mounting seat, the upper end of the mounting seat is provided with a carding mechanism, the right side of the mounting seat is fixedly provided with a mounting frame, the top of the mounting frame is sequentially provided from left to right with a conveying belt mechanism, an adjusting assembly and two mounting plates, the two mounting plates are fixed on the front and back sides of the mounting frame respectively, and the inner sides of the two mounting frames are slidably connected with sliding blocks one through electric push rods.The controller system is used for adjusting and matching between the conveying belt mechanism, the sliding frame and the rollers, so that the carding mechanism can be used for flat laying and discharging cotton yarn and stacking in various modes.The controller system is used for controlling and adjusting the adjusting assembly and the stacking assembly, so that the carding mechanism can be used for cylindrical discharging and stacking of the cylindrical cotton yarn in various modes on the basis of flat laying and discharging the cotton yarn.

The present invention relates to a combing machine (K) with several combing heads (1), wherein the combing heads (1) each have a gripper apparatus (2) through which a cotton strip (Wb) provided by a cotton roll (W) can be guided, further comprising a fixed (5) and a round comb (4) for combing out combed pieces from the cotton strip (Wb), a pair of tear-off rollers (6) for tearing off a fiber beard from the cotton strip (Wb) and for soldering the fiber beard to a fiber nap (Ff), wherein each combing head (1) is followed in the material flow direction by a take-off table (11), means for consolidating the fiber nap (Ff) into a nonwoven (V), and a belt funnel (41) for forming the nonwoven (V) into a fiber strip (F1 - F8). The invention is characterized in that each comb head (1) has a single pair of tear-off rollers (6), and that the take-off table (11) has a first rising section (12) onto which the fiber web (Ff) formed by the single pair of tear-off rollers (6) is guided to a continuously rotating pair of take-off rollers (8).
