    1536332 Babies napkins FAMECCANICA SpA 2 April 1976 [4 April 1975] 13514/76 Heading A3V A pilch comprises a sheet of liquid-impermeable material having a recess for absorbent material, the recess being moulded by heat and temperature and having a bottom which is corrugated or undulated, the ends of the sheet being provided with tie strips. The moulding from stock material 14 is performed in a drum 1 with pressure chambers 4-11. When pads are inserted a liquid permeable layer 22 is added and fastening tapes added.

    The invention relates to light industry, in particular, to devices for making baby diapers. A device for manufacturing molded parts is known, comprising a drum mounted for rotation and carrying on the outer surface of a die, connected to a sealed chamber installed inside the drum and connected to a vacuum source {1. A disadvantage of the known device is its limited capabilities, since it only provides processing of thick and hard strips and it is impossible to make a thin strip and to carry out a qualitative deformation of a product like diapers and pants to support diapers. The purpose of the invention is to expand technological capabilities. This goal is achieved by the fact that the device for making diapers, comprising a drum mounted rotatably and carrying on the outer surface of the matrix, connected to a sealed chamber installed inside the drum and connected to a vacuum source, additionally has an arcuate section chamber mounted above the drum . means for successively increasing the pressure and temperature in each subsequent section in the direction of rotation of the drum, with this inner side of each ma Ritsa made corrugated, and the drum is perforated FIG. 1 shows the proposed device, a general VIEW} in FIG. 2 is a drum with an arcuate sectional chamber, side view in FIG. 3 — means for transporting a belt of material. The device for making diapers comprises a drum 1 mounted on a shaft 2 rotatably and carrying on the outer surface of the matrix 3, the configuration of which corresponds to the desired configuration of the pockets of 4 diapers. The dies 3 are connected to a fixed hermetic chamber 5 installed inside the drum 1 and connected to a vacuum source 6. The device additionally has an arcuate section chamber 7 installed above the drum 1, having
    means for the subsequent increase in pressure and temperature in each subsequent toroidal section 8-15 in the direction of rotation of the drum 1; the sections above the walls are separated by walls 16, in which valves are preferably installed (not shown). There is a means for transporting a ribbon of material, e-shaped in the form of a belt 17, rollers 18 and pressure rollers 19 arranged around the barrel 1. The non-leaky chamber 5 covers the inner surface of sections 9-14, the inner side of X1 of each matrix 3 is corrugated, and the drum 1 has perforations. “For feeding the plastic material tape 20, the device has a tape-feeding reel 21.
    The device works as follows.
    Tape belt 17, rollers 18 and pressure rollers 19 feed the belt 20 to the rotating drum 1 from the tape reel 21 synchronously rotating with the drum 1, the rollers 18 and the pressing rollers 19 press the edges of the tape 20 against the drum 1 under the influence of external pressure, internal depression and belt 17, while As in the central part of the belt 20 against the dies 3, the gradual influence of the temperature pressure forms a plastic material, pulling it out until it fully conforms to the shape of the corrugated surface of the dies 3 in sections 13. and 14. At the same time, there are small holes on the edges and / or the bottom surface of these matrices 3 (not shown).
    Thus, at the exit from the drum
    1 tape 20 contains in its central part a set of pockets 4 having a corrugated surface "
    The preferred increasing pressure and temperature in each subsequent section can be: for section 9, respectively, 0.05 atm, and for section 10 b, 0 atm, and then with the same increment for sections 11-13, and in section 14, the pressure can reach 0 , 15 atm, temperature. In the sealed chamber 5, a vacuum is maintained reaching 0.5-0.6 atm.
