摘要： A lap is produced in a spreading lapping machine (2) by successively folding a fiber web from a card (1), whereafter the lap is drawn in a drawing machine (4). The drawing machine (4) is provided with rotatable devices having peripheral fittings with spikes that are driven into the core of the lap. The degree of drawing is adjusted in such a way that most fibers in the drawn product are arranged in two directions which are substantially symmetrical relative to the lengthwise direction of said drawn product, and lie at an angle of 30.degree.-60.degree. C. relative thereto. The method is particularly useful for improving the mechanical properties of lapped products.

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 auxiliary carriage (16, 18) is located within a bottom passageway (70) which extends beneath the apron (8) and is separated from the apron by at least one partition-wall (72).The invention is applicable to the manufacture of nonwoven fabrics.

摘要： A high-quality nonwoven product is manufactured by making use of an intermediate product in which the majority of fibers are distributed in two orientations which form an angle with each other. The intermediate product is fed to a spreading and lap-forming machine (13A, 13B) which deposits the intermediate product in alternate pleats on its delivery belt so as to form a lap of superposed layers such that the majority orientations of the fibers within each layer form an angle with the majority orientations of the fibers of the contiguous layers, and the lap is subjected to a fixing treatment, for example by means of a needle-punching machine (14A, 14B).

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.
