Abstract:
Method to recover resin used in an optical disk in high purity. The method includes an abrading step and a peripheral face removing step. The abrading step abrades a recording surface, opposite to a reading surface where a substrate of the optical disk is exposed, until the substrate becomes exposed. Further, the peripheral face removing step removes portions adjacent to an outer peripheral face and an inner peripheral face.
Abstract:
A method for making a punched headliner 20 adapted to be installed in a motor vehicle is provided. The method includes placing a flange element 32 within a punch tool 12, the punch tool 12 comprising a punching component 14 and a mating component 16. The flange element 32 is placed abutting the mating component 16. A headliner blank 18 is placed within the punch tool 12 between the punching component 14 and the flange element 32. A punching edge 22, positioned on the punching component 14, is moved towards the mating component 16. The headliner blank 18 is thereby pressed between the punching edge 22 and the flange element 32. The punching edge 22 is pressed into contact with the flange element 32 such that a shearing edge 54 is formed on the headliner blank 18 and a waste component 46 is separated from the headliner blank 18.
Abstract:
An apparatus for cutting a sheet-shaped material, comprises the first blade, the second blade, the first holding members and the second holding members. The second blade is disposed to face the first blade so that a sheet-shaped material to be cut is placed between the first blade and the second blade. The first holding members are disposed on the opposite sides of the first blade, respectively. Each of the first holding members has a cushioning property by which each of the first holding members is elastically deformed to press the sheet-shaped material during cutting operation. The second holding members are disposed on the opposite sides of the second blade, respectively. Each of the second holding members has a cushioning property by which each of the second holding members is elastically deformed to hold the sheet-shaped material during cutting operation. The first holding members and the second holding members hold the sheet-shaped material from the opposite surfaces thereof when cutting the sheet-shaped material by means of the first and second blades.
Abstract:
The invention provides a method of shaping optical storage devices (OSD) by placing an OSD between a die set having a male die and female die corresponding to a desired shape and advancing and retracting the die set so as to die-cut the OSD to the desired shape to form a shaped OSD, the shaped OSD products formed therefrom and the die set.

Abstract:
Disclosed is a flex die punching apparatus for forming an aperture in at least one sheet of material. There is a flexible, extrudable platen which, upon exertion of a force against it, extrudes at least a portion of at least one sheet of material through an aperture of a die. The flexible, extrudable platen may have a punch feature, corresponding to the shape and position of the die aperture, which assists in the extruding of the flexible, extrudable platen through the die aperture and also in the formation of the aperture in the sheet of material. In another embodiment of the invention, there may be a second die wherein the at least one sheet of material is placed between the first and second dies to form the aperture in the sheet of material.
Abstract:
A rotatable cylinder to which is secured a unitary sleeve having cutting lands for cutting and creasing sheet material such as paper and cardboard. The sleeve is secured to the cylinder to prevent relative movement during the cutting process.
Abstract:
In the method for blanking out a sheet material (1) between a punch (4) and a die (6) having a sharp edge (7), the punch (4) is formed by a heterogeneous composite elastic material having localized regions (4a) having a relatively higher hardness, and complementary regions (4b) having a relatively lower hardness.
Abstract:
Apparatus for severing material at selected locations comprises first and second dies. Each of the dies has sheet-severing elements in the form of narrow projections extending above the surface of the main body of the respective die. The sheetsevering elements define a layout of the selected material locations to be severed. At least one of the dies comprises a plurality of separate discrete die sections. An additional die section is provided as a replacement for each die section in the event of damage thereto.
