Abstract:
This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.
Abstract:
While a first coating gun 405 is being moved along a peripheral edge portion 100a of one surface of a multilayer glass panel 100 horizontally placed on a first worktable 20, the first coating gun 405 discharges a molding material to coat the peripheral edge portion 100a with the molding material over its entire length, molding a glazing gasket 110 thereon. An inverting mechanism 60 inverts the multilayer glass panel 100 with the molded glazing gasket 110 such that the other surface of the multilayer glass panel 100 faces upwardly. Then, a second coating gun 505 is moved along a peripheral edge portion 100b of the other surface of the multilayer glass panel 100, which is horizontally placed on a second worktable 30, and simultaneously discharges a molding material to coat the peripheral edge portion 100b with the molding material over its entire length, molding a glazing gasket 110 thereon.
Abstract:
A method for manufacturing a Z-directed component for insertion into a mounting hole in a printed circuit board according to one example embodiment includes simultaneously extruding a plurality of materials according to the structure of the Z-directed component to form an extruded object and forming the Z-directed component from the extruded object. In one embodiment, the extruded object is divided into individual Z-directed components. In one embodiment, the timing of extrusion between predetermined sections of one of the materials is varied in order to stagger the sections in the extruded object.
Abstract:

Abstract:
The object of the present invention is to provide a method and an apparatus for molding an annular member capable of accurately molding an annular member into a predetermined cross-sectional shape even if the annular member has a thick-walled inner peripheral part and a thin-walled outer peripheral part. The method for molding a bead filler (11) including a thick-walled inner peripheral part (11a) and a thin-walled outer peripheral part (11b), the method comprising the steps of extruding, into an annular shape, rubber (R1) by a first extruder (30) onto a molding table (20) through a first die (31) provided with an opening having the same cross-sectional shape as that of the inner peripheral part (11a) while the molding table (20) is rotated, and molding the inner peripheral part (11a); and extruding, into an annular shape, rubber by a second extruder (40) onto the molding table (20) through a second die (41) provided with an opening having the same cross-sectional shape as that of the outer peripheral part (11b) while the molding table (20) is rotated, and molding the outer peripheral part (11b).
Abstract:
A system for applying plastic clips to tubular products comprises a die comprising a peripheral face, an arcuate wall forming a half-cylindrical bore separating the die peripheral face into a first and a second side, and a groove extending from the first side, through the arcuate wall and the second side, and forming a slot in an outer edge of the die; a punch comprising a peripheral face, an arcuate wall forming a half-cylindrical bore separating the punch peripheral face into a first and a second side, and two grooves extending from the first side to the second side; and a cylinder for moving the die and the punch from a first position in which the die peripheral face and the punch peripheral face are adjacent, to a second position in which the die peripheral face and the punch peripheral face are remote.
Abstract:
An extruder comprises an extruding section, a chamber drum, and a forming section. The extruding section kneads and extrudes a kneaded material including a ceramic raw material. The chamber drum includes a first space portion which extends from the extrusion port side of the extruding section in an extruding direction and allows the kneaded material to flow in the extruding direction, and a second space portion which extends from a downstream side of the first space portion in a downward direction, allows the kneaded material to flow in the downward direction different from the extruding direction, and has a discharge port to discharge the kneaded material. The forming section includes a die through which the kneaded material discharged through the discharge port of the chamber drum is pushed out, to extrude and form ceramic formed bodies.

Abstract:
The present invention relates to a process for manufacturing a shaped article such as tubes, and hoses comprising processing a fiber-reinforced thermoplastic polymer in an extruder apparatus.
Abstract:
An apparatus and method for producing a substantially spiral shaped food product is disclosed herein. The apparatus includes a die defining a plurality of apertures disposed in a circle about a center. The apparatus also includes at least one cutting blade disposed for rotation about the center and operable to intermittently pass fully across each of the apertures during rotation. The apparatus also includes a plurality of slicing blades arranged for individual rotation about one of the plurality of apertures. The plurality of slicing blades are also arranged for continuous extension less than fully across the one aperture. The apparatus also includes a planetary coupling arrangement operably disposed to facilitate reciprocating rotation between the at least one cutting blade and the plurality of slicing blades.
