20080292740 | SHEET/FILM MOLDING APPARATUS AND SHEET/FILM MOLDING METHOD - A sheet/film molding apparatus includes: a main roll sandwiches and presses, with a touch roll, a resin molten sheet and conveys the sandwiched and pressed resin sheet; and a separating roll separates the resin sheet from an outer peripheral surface of the main roll and conveys the resin sheet. The separating roll has a rubber roll and a metal elastic external cylinder having the rubber roll housed therein and being eccentrically positioned to the rubber roll and thin and easily elastically deformed. Cooling water is supplied between the rubber roll of the separating roll and the metal elastic external cylinder. The resin sheet between the main roll and the metal elastic external cylinder is cooled by allowing the rubber roll to make pressure contact with an inner peripheral surface thereof. The separating roll separates the resin sheet from the outer peripheral surface of the main roll. | 11-27-2008 |
20090196947 | Continuous metal extruder - A continuous metal extruder that comprises a rotatable member having an extrusion screw portion for transporting metal to be extruded in an axial direction of said rotatable member, and a fixed part, is disclosed. In a method the rotational member and the fixed part are biased in relation to each other. An extruder for carrying out the method comprises a spring element for the biasing. In one embodiment there is a thrust bearing arranged between the rotational member and the fixed part, said thrust bearing has a first bearing race facing said fixed part and a second bearing race facing a part of said rotatable member. The spring element is arranged to bias the thrust bearing, and thereby the rotational member and the fixed part in relation to each other, by exerting along said axial direction an expanding force between at least one of the of the following: the first race of the thrust bearing and the fixed part; and the second race of the thrust bearing and said part of the rotatable member. | 08-06-2009 |
20090297651 | NOZZLE BLOCK FOR ELECTROSPINNING - Disclosed is a nozzle block for electrospinning which is able to simultaneously electrically spin two or more different types of polymer spinning dopes, wherein a single-layer distribution plate for dividing a planar space within the nozzle block into two or more segments is installed within the nozzle block. The apparatus is simple because a single-layer distribution plate is installed instead of a conventional multi layer distribution plate. A hybrid nano fiber laminate can be prepared without any additional laminating procedure because two or more different polymer spinning dopes can be simultaneously electrically spun through different nozzles arranged within the same nozzle block. It is possible to prepare a hybrid nano fiber nonwoven fabric or filaments or the like composed of two or more types of nano fibers different in thermal properties or physical properties because their fiber diameter or polymer type are different from each other. | 12-03-2009 |
20100178373 | APPARATUS AND METHOD FOR PROTECTING LINED CONCRETE PIPE DURING THE MANUFACTURING PROCESS - At the filling station of a dry cast pipe making machine for making pipe lined with a plastic liner, the liner is first placed over the core and then a plurality of spaced-apart, removable L-shaped plates are secured around the top edge of the core. One leg of each plate extends inside the core with the other leg extending downwardly over the top edge of the liner. The plates are removably held in place on the core by the use of a clamping device, such as a vise-grip, for example. Once the form is filled with concrete and ready for the pressure heading step, the downwardly extending legs of the plates serve as ‘shoehorns’ to guide the pressure header over the top of the liner and prevent damage to it. In addition, the plates will assist in centering the core within the jacket. | 07-15-2010 |
20110003024 | METHOD AND APPARATUS FOR PRODUCING A DISLOCATION-FREE CRYSTALLINE SHEET - A dislocation-free sheet may be formed from a melt. A sheet of material with a first width is formed on a melt of the material using a cooling plate. This sheet has dislocations. The sheet is transported with respect to the cooling plate and the dislocations migrate to an edge of the sheet. The first width of the sheet is increased to a second width by the cooling plate. The sheet does not have dislocations at the second width. The cooling plate may have a shape with two different widths in one instance. The cooling plate may have segments that operate at different temperatures to increase the width of the sheet in another instance. The sheet may be pulled or flowed with respect to the cooling plate. | 01-06-2011 |
20110165280 | METHOD TO ACCURATELY CONTROL SIZE, VELOCITY, AND RELATIVE POSITION SETS OF RECLOSABLE MECHANISM - The apparatus includes an extrusion die and further includes a main or primary extruder for the supply of material, such as low density polyethylene, to form the tubing for the manufacture of reclosable packages, bags or pouches. The apparatus further includes at least one secondary extruder, or co-extruder, for the extruding of each reclosable profile onto the tubing. The speed of the co-extruders is controlled so as to control the extrusion of the reclosable profiles. | 07-07-2011 |
20120282364 | Method and Apparatus For Forming A Batt of Particulate Material for Use as A Component in an Absorbent Core Assembly - A method and apparatus for forming a batt of particulate material which may be used in an absorbent article. The apparatus may include a vacuum zone, an air impermeable fence zone adjacent to the vacuum zone, and an air permeable fence zone adjacent to the vacuum zone. The air permeable fence zone may comprise an ambient air entry conduit in communication with an ambient air exit port. The method may include providing a laydown drum and a first web of material, positioning the first web of material substantially adjacent to the laydown drum, generating a vacuum through the laydown drum, depositing particulate matter onto the first web of material, and rotating the laydown drum. | 11-08-2012 |
20130022699 | SHEET FORMING APPARATUS FOR USE WITH DOCTOR BLADE - A sheet forming apparatus includes a supply port for supplying a slurry, a discharge port for discharging a green sheet, a first slurry spreading chamber, a second slurry spreading chamber, and a third slurry spreading chamber that are disposed between the supply port and the discharge port, and joining holes through which the first, second, and third slurry spreading chambers are joined to each other. At least two of the joining holes are disposed one on each side of the supply port along a transverse direction of the green sheet. | 01-24-2013 |
20140295017 | WIDE CASTING BELT, METHOD FOR MANUFACTURING A WIDE FILM, AND WIDE FILM - Disclosed is a wide casting belt, and more particularly, a wide casting belt used for manufacturing a film in a gel state by casting dope used during the manufacture of a polarizing plate for a liquid crystal display, and an optical compensation film, etc. A method for manufacturing a wide film using the wide casting belt, and a wide film manufactured with the wide casting belt are disclosed. | 10-02-2014 |
20140363533 | MANUFACTURING DEVICE FOR A LIGHT GUIDE PLATE - A manufacturing device includes a feeder, a first pressing roller, a second pressing roller, a third pressing roller, a transmission assembly, and a driving assembly. The first pressing roller and the second pressing roller cooperatively press a hot melt adhesive from the feeder to obtain a preprocessed light guide plate. A temperature of the second pressing roller is lower than a temperature of the hot melt adhesive. The third pressing roller separates the preprocessed light guide plate from the second pressing roller to obtain a light guide plate. The transmission assembly connects the second pressing roller and the third pressing roller. The driving element is connected to the transmission assembly, and drives the transmission assembly to rotate the third pressing roller around the second pressing roller, and thus adjusting a contact area and a contact time between the light guide plate and the second pressing roller. | 12-11-2014 |
