To provide a method of manufacturing a T-shaped wearing article less like to leave waste material. [MEANS FOR SOLVING THE PROBLEMS] A web (W) is divided into a first divided sheet (W1) and a second divided sheet (W2) by slitting the web along a predetermined first cutting line (CL). The first divided sheet (W1) and the second divided sheet (W2) are separated from each other. A core part (2) is disposed between the first divided sheet (W1) and the second divided sheet (W2) to form a composite body (10). Respective divided sheets (W1, W2) are so cut along a transverse second cutting line (Ch) that the portions of the sheets forming back parts (3L) are longer than the portions forming front parts (3S) in the conveying direction (X) of the divided sheets (W1, W2).

The invention relates to a thermocompression molding method for a folded sandwich circular frustum shell of fiber reinforced composite material, which relates to the field of composite material molding design. The invention solves the problem that there is no process for preparing the pleated sandwich circular frustum shell at present. The preparation method of the present invention comprises the following steps: 1. Preparation of the pleat core: cleaning and assembling the core mold; applying a release agent; cutting, laying, folding, and curing of the prepreg; stripping the pleat core; 2. Preparation of the inner panel: cleaning the panel mold; applying a release agent; assembling the main body of the inner panel mold; cutting, laying, laying, and curing of the prepreg; demoulding of the inner panel; 3. Preparation of the outer panel: fiber reinforced composite material The preparation of the outer panel is basically the same as step 2; 4. Assembly, bonding and secondary curing of the pleated core and the inner and outer panels: pasting of the adhesive film; gluing of the pleated core and the inner and outer panels; curing of the pleated sandwich circular frustum shell; panel mold disassembly. The invention is used for preparing fiber-reinforced composite folded sandwich circular frustum shells.

The invention discloses a wine box forming machine, and the forming machine comprises an ash box conveying belt, a surface paper conveying belt, an ash box transmitting and positioning mechanism, an ash box feed mechanism, an ash box periphery paper laminating mechanism, a paper box bearing and rotating mechanism, a first blank pressing mechanism, a second blank pressing mechanism, a surface paper cementing and laminating mechanism, an ash box bottom paper pressing mechanism and a box unloading mechanism. The forming machine can precisely position the surface paper and the ash box during lamination, when the ash box and the surface paper are laminated, the periphery of the ash box is firstly laminated, and then the bottom of the ash box is laminated so that they only have a jointed seam after lamination, whole forming paper box has the smooth outer surface, high quality and excellent effect, during the process, the surface paper is saved, according to production demands, the laminated width, height and length between the surface paper and the ash box can be automatically adjusted, thus the forming machine is suitable for formation of different-size paper boxes and has high intelligence, besides the paper box grabbing mechanism can precisely unload the finished paper box, and the wine box forming machine is high in yield and convenient to use.

The invention discloses a flat paper tube reeling machine, comprising a rack, a paper placing device which is connected to the rack, a paper guiding device, a pasting device, a, paper cutting device, a paper feeding detaching device, a tube reeling device and a tube cutting device, wherein the pasting device comprises a sizing roller; a paper passing device is fixedly arranged between the pasting device and the paper cutting device; an paper inlet surface of the paper passing device and the top surface of the sizing roller are in a same plane; and an paper outlet surface of the paper passing device and a paper cutting surface of the paper cutting device are in a same plane. According to the flat paper tube reeling machine provided by the invention, the thickness of paper can be reduced; and during the tube reeling, the adherence force between two pieces of paper is increased, so that the paper tube quality is improved.

The utility model relates to a composite mold for preparing a folded sandwich circular frustum shell of a fiber-reinforced composite material, which relates to the field of composite material molding design. The invention solves the problem that there is no process for preparing the pleated sandwich circular frustum shell at present. The combined mold of the present invention includes a core mold and a panel mold; the core mold includes a male mold main body, a female mold main body, an inner support of the first core mold, an inner support of the second core mold and an outer support of two core molds. The main body of the mold is a hollow circular table shell structure composed of several male molds. The inner wall of the main body of the male mold is a circular table surface, and the outer wall of the main body of the male mold is provided with a plurality of quadrilateral units. The wall surface is a circular table surface, and a plurality of quadrilateral units are arranged on the inner wall surface of the female mold, and the quadrilateral units on the inner wall surface of the female mold are completely engaged with the corresponding quadrilateral units on the outer wall surface of the main body of the male mold. The invention is used for preparing fiber-reinforced composite folded sandwich circular frustum shells.

The invention relates to the technical field of textile fabrics, in particular to a knitted fabric with different elastic zones. A knitted fabric with different elastic zones, comprising: at least one set of three-dimensional areas and plane areas connected on both sides of the three-dimensional areas, the yarns between the three-dimensional areas and the plane areas are connected by loops, and the The elasticities of the three-dimensional area and the planar area are different so as to be suitable for different modeling requirements. The three-dimensional area is braided by the BT yarn and the first spandex loop, and the planar area is knitted by the FD yarn and the second spandex loop. By connecting the spaced areas with different elasticities with loops on the same piece of fabric, it is possible to meet the different elastic requirements for different parts of the fabric when making underwear, and the two spaced areas with different elasticities are connected by loops. The transition between different elastic regions is natural and smooth, which not only improves the physical properties of the fabric, but also enhances the comfort when next to the body and reduces production and production costs.

The production method of corpse-holding bag uses thermoplastic chemical material and adopts blow-moulding process to form, and adopts hot-press method to press-conjoin opened and of one end of corpse-holding bag, at the same time a zipper opening is hobbed on proper position of the corpse-holding bag for mounting zipper, and according to the required length a first closed end and second closed end are hot-pressed and conjoined, and another zipper opening is hobbed, and the between said opened end and first closed end can be formed into a closed corpse-holding bag, and the second closed end and another zipper opening can be simulataneously formed, and when the third closed end is hot-press, and between of second closed end and third closed end also can be formed into closed another corpse-holding bag. Said method can make closed end and zipper opening form simultaneously, can greatly raise its production speed.
