    摘要: A web of fibers (4) is conveyed by conveyor-belts (2, 5) which pass around rollers. A number of rollers are carried by an input carriage (10) and an output carriage (14), said carriages being capable of displacement in reciprocating motion above an apron (8) which moves in a direction parallel to the axes of the rollers and collects the web (4) in the form of a lap (6). A guide roller (34) defines for the web (4) on a first conveyor-belt (2) a section (22) which is inclined towards the pinching line and is located upstream of said line, said pinching line being defined by two adjacent rollers (35, 61). The pinching roller (35) associated with the first conveyor-belt (2) causes it to make a turn through an angle (B) within the range of 90 degrees to 180 degrees. The pinching line is located in an intermediate angular position between the beginning and the end of said turn.The invention is applicable to the manufacture of nonwoven fabrics.

    摘要: A web of fibers (4) is conveyed by conveyor belts (2, 5) which pass around rollers (32 to 43, 60 to 69). Some of these rollers are carried by main carriages (10, 14) which are capable of displacement in reciprocating motion above an apron (8) which moves in a direction parallel to the axes of the rollers and collects the web (4) in the form of a lap. Auxiliary carriages (16, 18) are provided for maintaining the length of the paths of the conveyor-belts (2, 5) at a constant value in spite of the reciprocating movements of the main carriages (10, 14). Each main carriage (10, 14) is connected to an auxiliary carriage by coupling means (92, 96) which are less extensible than the conveyor-belts (2, 5) and are so arranged as to be put under tension under the action of the means (84, 88) for driving the carriages.The invention is applicable to the manufacture of nonwoven fabrics.

    摘要: An unwinding carriage (14) is fed with a fiber web (4). This unwinding carriage (14) is displaced in a to-and-fro movement, causing it to deposit the web (4) on an exit conveyor (8) driven transversely to the movement of the unwinding carriage (14), so as to produce a lap (6) consisting of successive breadths of web inclined alternately in relation to the longitudinal direction of the exit conveyor (8), these breadths being joined by means of folds defining the edges of the lap produced (6). The advance of the exit conveyor (8) at the moments of the changes in direction of the unwinding carriage (14) is maintained. During these changes in direction, the unwound quantity of web (4) is restricted so as to exert on the fibers, between the exit conveyor (8) and the unwinding carriage (14), a pull tending to orient the fibers which form the folds of the web in the lap (6) parallel to the longitudinal direction of the exit conveyor (8). The invention is used particularly for making needled products.

    摘要: A brush conveyor, such as a velvet needling machine, has an assembly of contiguous brushes disposed in transverse rows, and a drive source for this assembly of brushes which forms a conveying plane having a predetermined direction of displacement to constitute an upper face of the conveyor. Each brush includes a body including, on its upper face, holes which are provided for receiving a tuft of hair and, on its lower face, connecting apparatus to fasten this brush to a drive source. The drive source has several parallel drive belts or chains placed between at least two drive cylinders running in the same direction. The conveyor also has a support structure for supporting the brush bodies forming the conveying plane. This support structure includes a support table having several flat support parts separated by spaces provided for the drive belts or chains. With each transverse row of brushes a connecting rail, attached to at least one brush in a row, extends along the width of the conveyor, disposed perpendicular to the direction of displacement. The connecting rail is also attached to the drive belts or chains.

    摘要: An installation includes a carding machine (1), and a distributor-layer (2) depositing the card (1) web (6) in a reciprocating motion on a delivery belt (8) moving transversely. The resulting intermediate lap (16) is conveyed to a needling loom (3) to produce a consolidated lap (24). A measuring station (28) scans the consolidated lap (24) profile and transmits it to a processing unit (32) where the profile is compared to a set reference input by a terminal (33). The variations in width cause a corresponding modification in the width deposited by the distributor-layer (2) by a link (36). The local surface weight variations cause a corresponding modification of the controls applied to the carding machine (1) capable of longitudinally profiling the web (6). The invention is useful for controlling an installation for obtaining a finished product.

    摘要: A carding machine or other web production device [(1)] supplies a crosslapper [(2)] with two elementary webs [(15a, 15b)] constituting a lappable web [(16)] which is deposited in a reciprocating manner on a transverse output belt [(26)]. In the device [(1) means of] adjustment of the speed of rotation of doffers [(13a, 13b)], of condensers [(17, 18)], of detachers [(19a, 19b)], of the drum [(4)] and/or of the feeder [(7)], and/or [means of] adjustment of the drum-doffer spacing affect the weight per unit area of the elementary web produced taking account of the weight per unit area desired at each point in the width of the fleece [(67)] to be formed on the output belt [(26)]. There is determined the delay length exhibited by each elementary web cross-section undergoing the adjustment of weight with respect to the section of lappable web in the process of being deposited. From this there is derived the position at which each web cross-section will be deposited when it is undergoing the adjustment of thickness and consequently the weight adjustment to be applied to it. [Utilization] The present invention is useful for producing fleeces of highly varied profiles with great industrial flexibility.

    摘要: A needle loom including a support and a stripper defining a path for a fiber lap. A needle board supported by sliding shanks moves back and forth between a maximum penetration position and a retracted position, by means of a connecting rod/crank assembly including a connecting rod hingedly connected to the sliding shank. A slide bearing remote from the needle board has a greater diameter than the other slide bearing, and engages a tubular portion of the shank. The hinge connection between the connecting rod and the sliding stank is located within the axial section covered by the slide bearing and the interval therebetween. For this purpose, the hinge is arranged in the tubular portion. Bearing wear, extraneous stress and vibration may thus be reduced.

    摘要: The invention concerns a stretcher comprising a carriage (21) subjected to a back-and-forward motion (2) for depositing in successive segments (2a . . . 2d) a web of fibres (2) on an outgoing conveyor (6) moving along a direction (9). In order to produce ranges of different plies in the transverse profile of the lap (4) formed on the outgoing conveyor (6) by the web deposited in mutually overlapping segments, the points of inversion of direction (21) in the backward and forward motion of the carriage are different. As a result the successive folds (2ab, 2cd; 2bc, 2da) of the same direction are differently positioned, and the number of web plies in the lap is not the same over the whole width of the lap. The invention is useful for streamlining the lap freely and accurately.
