Forming tools includes an upper holder; a lower holder; a punch having a punch body which can be attached to/detached from the upper holder and the lower holder; an ejector being disposed movably in a vertical direction around a convex portion provided on a face of the punch body; a resilient unit for urging the ejector, the resilient unit being provided on a back face of the punch body; a die having a die body which can be attached to/detached from the upper holder and the lower holder, the die...

A press station for a forming machine for forming articles from paper has a chamber consisting of two halves. The two halves of the chamber are able to be closed together and the chamber can be evacuated through a main vacuum manifold in order to bring the upper die mounted on a first platen into pressing contact with a fragile moulding positioned on a second platen in order to form the required article.

A flat woven papermaker's forming fabric having a paper side layer and a machine side layer interconnected by pairs of weft binder yarns. Each of the binder yarn pair members in sequence interweaves with a portion of the paper side layer warp yarns in segments of the weft yarn path so as to complete an unbroken weft path in the paper side layer weave pattern, and to provide an internal paper side layer float. Each of the binder yarn pair floats interlaces with a machine side layer warp yarn so a...

A method and apparatus for forming the base of a can are described. The base forming apparatus is typically a dome station for forming a dome on the base of a beverage can. The dome station is mountable onto a dome door of a bodymaker press, thereby avoiding the common failure of mounting bolts. A complete polyurethane ring (20) is used to create overtravel force and maintain consistent and symmetrical loading on the tooling. A compact biasing arrangement is used to simplify maintenance of the t...

An electrostatic image forming apparatus is disclosed. The image forming apparatus contains a toner used in the developing means having saturated moisture content at a temperature of 30.degree. C. and a relative humidity of 80% of within the range of from 0.1 to 2.0% by weight, and the photoreceptor contains a siloxane resin having an electric charge transfer ability and a crosslinked structure in the surface layer.

A papermaker's fabric for use as a forming fabric. The fabric may include bondable or meltable monofilament yarns which may be formed from materials that retain substantial strength and tenacity after thermal treatment. Further, the remaining yarns in the forming fabric may be formed from materials that have a higher melting temperature than the monofilament material that will be thermally bonded or melted.

A mold used to form a rubber or resin article which includes a shaping surface for shaping a surface of an object to be molded, and a vent structure for releasing air between the shaping surface and the surface, wherein the vent structure includes EDM vents each having a gap of not more than 0.1 mm at the shaping surface.

The invention relates to a method for working or forming a workpiece by flow-forming, particularly for the manufacture of internal teeth on the workpiece, in which a cup-shaped preform or blank is axially fixed against a tool chuck and pressed by means of at least one rolling body onto said tool chuck and the blank is rotated relative to the rolling body, the at least one rolling body, at the start of forming, at the open end of the blank is pressed against the cylinder wall area thereof and in ...

This machine includes a moving condenser and an undercarriage having a solid plate confronting a part of the perimeter of the condenser. The condenser may be a rotating foraminous screen, or an endless foraminous belt. There is a duct inside the condenser, through which air is sucked to draw fibers onto the screen, and an adjustable baffle for determining the effective area of this duct. Fibers are sucked into the space between the plate and condenser by the air flowing through the condenser and...
