Provided is an improvement in a method for manufacturing a slit carbon fiber bundle. The method for manufacturing a slit carbon fiber bundle of the present invention is a method including a step of forming a resin film on one surface of a flat carbon fiber bundle to obtain a single-sided coated carbon fiber bundle, and a step of partially slitting the single-sided coated carbon fiber bundle using a slitter roll to obtain a slit carbon fiber bundle, which has been split into sub-bundles, wherein in the step of slitting, the single-sided coated carbon fiber bundle contacts a circumferential surface of the slitter roll on a surface where the resin film has been formed.

Methods of cutting a flooring web into rectangular flooring tiles such that at least one vertical cut along the length of the web defines a shorter edge of the rectangular tiles and horizontal cuts across the width of the web define the longer edges of the rectangular tiles.

A process for the production of spunbonded nonwoven (1) is shown, wherein a spinning mass (2) is extruded through a plurality of nozzle holes (4) of at least one spinneret (3, 40, 50) to form filaments (5) and the filaments (5) are drawn, in each case, in the extrusion direction, wherein the filaments (5) are deposited on a perforated conveying device (10) to form a spunbonded nonwoven (1) and wherein the nozzle holes (4) of the spinneret (3, 40, 50) are arranged along a main axis (6) oriented in a transverse direction (12) to the conveying direction (11) of the conveying device (10) so that the spunbonded nonwoven (1) formed on the conveying device (10) extends in this transverse direction (12). So as to enable the spinning width and the basis weight distribution of the spunbonded nonwoven to be adjusted reliably and, respectively, to allow the basis weight distribution to be kept constant during operation by means of the process, it is suggested that the spinning mass throughput (31) of the nozzle holes (4) is adjusted variably along the transverse direction (12).

A topping sheet forming method includes: a division step of cylindrically winding a textile original fabric, obtained by weaving longitudinally aligned tire cords into a cord fabric by use of weft yarns, to form an original fabric roll and cutting off the weft yarns in predetermined widthwise positions by using a wire wound on the original fabric roll in a predetermined winding angle range to divide the textile original fabric into narrow textile original fabrics; and a topping step of topping at least one surface of each of the narrow textile original fabrics with unvulcanized rubber.

A method for realising articles having a predetermined area and aesthetic appearance, which includes using frames (1A, 1B, 1C) to each of which a portion (P1, P2, P3) of material having a prevalent flat extension can be removably hooked, comprising, in order, following steps: hooking a first portion (P1) of the material to a first frame (1A); carrying out, on the first portion (P1) hooked to the first frame, punching (G1) and stitching (G2) operations; carrying out, on the first portion (P1) hooked to the first frame (1A), cutting operations (G3) for defining a corresponding article (A) having predetermined area and aesthetic appearance defined by the combination of the profile of the article and by the mutual arrangement of the punching (G1) and the stitching (G2); releasing the article (A), and relative scrap (Z),from the first frame (1A).

An aspect of the present invention provides a raw fabric cutting device. The device comprises: a support portion for supporting a raw fabric; a compressing portion for evacuating the space between a cover arranged on the raw fabric and the support portion such that the raw fabric is compressed; a cutting portion transferred above the support portion so as to cut the raw fabric; and a sealing portion transferred together with the cutting portion and configured to supply a sealing member to an open area of the cover, which is exposed as the raw fabric is cut, thereby covering the open area, wherein the sealing portion comprises a sealing member cutting portion for forming a notch on at least one side of the sealing member in the transverse direction with regard to the direction of transfer of the sealing member.
