An extrusion die assembly configured to process a flow of extrusion material traveling in a downstream direction includes a first die component, a second die component and a third die component. The first die component includes a first channel that is substantially coaxial to a longitudinal axis. The second die component is received within a downstream side of the first die component and has a position that is adjustable along the longitudinal axis relative to the first die component. The second...

Center filled confections, such as gummy or jelly candies or fruit snacks are continuously produced by co-deposition into a mold without candy tailing to obtain products with substantially uniform side walls and little, if any, shell breakage and filler leakage or bleed-out problems. Decentering of the filler and its accompanying production of thin or weak shell walls is avoided by at least substantially preventing excessive flow of a fluid or liquid shell component along a single side of shell ...

An apparatus and method for molding plastic materials is provided comprising a mold having a first mold section (12) and a second mold section (14) with a mold cavity (16) disposed in between. A first gate design is provided by at least one first gate design mold member (40), and a second gate design is provided by at least one second gate design mold member. The first and second gate design mold members are removably attachable to, and interchangeable on, at least one of the first or the second...

Disclosed is an injection unit having a rotatable device for preventing reverse flow. To connect first flow channels formed in a spacer and second flow channels formed in a screw head when the metering is performed, and prevent reverse flow of resin by cutting off the first flow channels and the second flow channels when the resin is injected, the injection unit has a torsion spring as spring means between a shaft of the screw head and a screw, thereby rapidly preventing movement of the melted r...

A tubular film blowing head is provided with one outer and one inner nozzle ring between which a ring chamber is formed extending in a conical or parabolic manner towards the circular nozzle gap and of which the inner nozzle ring, which is provided with a central bore for exchanging the pressurized air, is connected by means of a screw connection to a central cone piece of the blowing head. This central cone piece has a bore that is aligned to the central bore. In order to create a screw connect...

Molding system for use with a mold having stationary mold portion and movable mold portion, molding system comprising: stationary platen configured to support stationary mold portion; movable platen configured to be movable relative to stationary platen, and movable platen configured to support movable mold portion; and extruder, including: barrel defining channel extending through barrel; liner received in channel, liner defining first conically-shaped end; machine nozzle connecting with the mo...

A three piece nozzle assembly for injecting molten plastic in an injection molding machine carrying out a high pressure, high volume continuous molding process to mold thin walled parts. A nozzle housing has an internally threaded dual diameter bore in one end which receives in one bore portion an externally threaded shank of a nozzle. A sleeve is threaded into the other bore portion and is tightened adjacent to a flange on the nozzle shank to lock the nozzle to the housing and prevent the press...

An extrusion nozzle, especially suitable for texturing proteinaceous materials, comprising an elongate body having a side wall defining an axial passage, at one extremity of the body the side wall having longitudinal slits defining at least two fins the free ends of which are turned inwardly towards the longitudinal axis of the passage. Other features of the invention are described in the following specification.

This invention is a trash compactor for compressing trash as it is moved in a horizontal direction. The compactor includes an elongated chamber comprising a rectilinear section into which the trash is placed, a power member for forcing the trash through the rectilinear section, where the trash is initially compacted and, a curvilinear section through which the trash is pushed by the movement of trash through the rectilinear section. The curvilinear section is of sinuous or S-shape configuration ...

A carbon black, and the like, pelletizer having a rotor with a multiplicity of flat, bladelike toolholders attached to a rotatable shaft and each mounting at the end thereof a pelletizing tool in the nature of a pin. The toolholders are so designed and arranged as to effectively form a helix, in conjunction with the pins, for advancing the material during pelletizing to an outlet, and one embodiment provides a double helix for substantially working all of a product at all times.
