摘要:
Apparatus for forming an air formed fibrous web has a form member on which fluent fibrous material is deposited in an air formed deposition process. The fibrous web may be used as an absorbent core of an absorbent article. The form member has a forming surface with a pocket for making a thicker portion of the fibrous web such as for a liquid holding formation of the absorbent core. The pocket has a bottom surface which is shaped so that additional material will be deposited in the pocket. A form member and an absorbent core made using the apparatus are also disclosed.

A heat treatment roll 2 is provided for continuously cooling or heating a treated object such as a resin sheet 5, which is used in an extrusion molded sheet manufacturing apparatus or the like. The heating roll 2 includes a hollow roll body 11 formed with many circular through holes 11a in the roll axis direction at a fixed close pitch on the same radius close to the cylindrical surface, wherein roll body 11 is formed by calculating the space between the circular holes 11a from the cylindrical surface to give the highest heat conduction efficiency with respect to the cylindrical surface and the lowest unevenness of temperature in the circumferential direction; a pair of side plates 12 and 13 which are fixedly provided on both end faces of the roll body 11 so as to be aligned with the roll body 11 and are provided with radial heating medium passages communicating with the circular through holes 11a in the cylindrical surface of the roll body 11; and a pair of rotating support shafts 12a and 13a extending on the same centerline on both sides of the heat treatment roll, each of which is fixedly provided integrally with one of the side plates, and has a heating medium passage communicating with the radial heating medium passages of the side plate in the axis center. Thereby, a cooling medium or a heating medium can be caused to flow from the heating medium passage in one rotating support shaft to the circular through holes in the roll body, and discharged from the heating medium passage in the other rotating support shaft, whereby a treated object such as the resin sheet 5 is cooled or heated.

A molding die assembly includes an upper die and a lower die, wherein at least one of the upper and lower dies is provided with a cavity corresponding to the shape of a rubber member to be molded, wherein at least one of the upper and lower dies is provided with an annular projection around a cavity. The distance between the upper and lower dies at the annular projection is made smaller than the distance between the opposed surface portions, other than the cavity, of the upper and lower dies. A rubber member produced by the above mentioned molding die assembly is also provided.

The apparatus for shaping thermoplastic materials, in particular for producing moulded parts with a large height of the said moulded part, comprises a suction-pressure bell (1) and a lower part (2) which can be locked to each other by a locking device (3). Resting on the lower part are a mould (8) and a clamping frame (9), while the upper clamping frame (10) can be securely clamped by working cylinders (11). In the locked state, the clamping frames are braced by a seal (15), which is arranged between the suction-pressure bell (1) and the upper clamping frame (10), extends over the entire circumference of the suction-pressure bell and is able to be pressed against the upper clamping frame by a pressure medium.
摘要:
Within a process for recycling of PET-material and/or objects of PET, the PET-material to be processed is heated and dried in the course of a pre-treatment step and simultaneously is crystallized at elevated temperature. This pre-treatment step is followed by a main-treatment step under vacuum. In this main-treatment step, the processed material is again dried and crystallized at a temperature that is higher than the temperature of the pre-treatment step. Preferably, also in the main-treatment step no plasticizing of the material takes place; the plasticizing or, respectively, melting of the material takes place only after the main-processing step. An apparatus for performing this process comprises a main processing pre-processing device (3) in which the processed material is dried and simultaneously crystallized at elevated temperature, and, if desired, is also comminuted. A main-processing device (4) is connected to this pre-processing device (3), in which main-processing device the supplied PET-material is dried, crystallized and heated to a temperature that is higher than the temperature within the pre-treatment device.
