The shim package further includes a connecting conduit disposed in fluid communication with the shim conduit, a reservoir disposed in fluid communication with the connecting conduit, and a slot disposed in fluid communication with the reservoir. The slot is configured to dispense the fluid onto an article. The die plate is disposed in abutting relationship to the shim package.

Method and apparatus for extrusion of thermoplastic handrail

A method of and apparatus for extruding an article of uniform cross-section, the article including a thermoplastic material and at least one cable for inhibiting stretch of the article. The cable is supplied to a respective tube and is conveyed between upstream and downstream ends. The thermoplastic material may be supplied to the downstream end of the tube. The thermoplastic material is brought together with the cable to embed the cable within the thermoplastic material, thereby forming a composite extrudate. The tube is configured to at least hinder movement of loose windings of the cable from the downstream end towards the upstream end, which may prevent or at least reduce incidence of birdcaging.

Extruder die assembly

An extruder assembly for forming a multi-layered composite is described, the extruder assembly includes an extruder head having a first and second flow passage, a first and second extruder in fluid communication with the respective first and second flow passage, and a splice bar having a first and second passageway extending from a rear side to an outlet side, and communicating flow from the first and second passageway to an outlet die. The splice bar further includes a groove located on the rear side of the splice bar and being positioned between the first and second passageway.

EXTRUSION HEAD FOR PIPES
20190134874 · 2019-05-09 · ·

An extrusion head for pipes includes a first female body provided with a first through cavity and a male element inserted and supported in the first cavity, and defining with it a hollow space. A second female body is attached to the first female body and provided with a second through cavity. An interchangeable male body is attached cantilevered on the male element and positioned in the second cavity. The second female body and the interchangeable male body define a passage gap in fluidic communication with the hollow space. In the second cavity, a housing seating is made in which an adjustment ring is positioned, through which the interchangeable male body is positioned through, and adjustment members configured to adjust the position of the adjustment ring.

MULTI-LANE DIE

A multi-lane die is provided. The multi-lane slot die comprises an upper body member, a lower body member, an upper shim, a separator shim, and a lower shim. The upper shim is positioned between the upper body member and the separator shim. The upper shim, the upper body member, and the separator shim define a first at least one dispensing channel that extends to a first at least one dispense opening of the multi-lane die. The lower shim is positioned between the separator shim and the lower body member. The lower shim, the separator shim, and the lower body member define a second at least one dispensing channel that extends to a second at least one dispense opening of the multi-lane die.

METHOD AND SYSTEM FOR PRODUCING AQUACULTURE
20180289040 · 2018-10-11 ·

The method and system produces a high-moisture aquatic feed that is stable in water and has a texture that more closely resembles naturally-occurring aquatic feedstocks. The system includes a tempering unit that is structured to allow an operator to control the temperature of a low-carbohydrate high-moisture extrudate after the extrudate leaves a conventional extruder. As the extrudate flows through a tubular matrix within the tempering unit, expansion of the extrudate is controlled to produce the high-moisture water-stable aquafeed.

Extruded Profile Produced with Rotating Shaping Dies
20180207698 · 2018-07-26 · ·

A new way to design lightweight, strong, material efficient, extruded and pultruded profiles, profile segments (4) and surfaces produced in profile production with rotating dies creating superior resistance to compression, bending and buckling, higher energy absorption and right strength in the right place, by: varying the thickness along (_t)+across the direction of extrusion, making reinforcing patterns (2, 3), vary the profile thickness (t, _t), and in some cases vary angles (10, 11) and pattern (2, 3) which increases the profile segments/surface resistance against compression, bending and buckling relative to the amount of material used and resulting in that one can make optimized beams and surfaces that have superior properties in terms of strength/weight, stiffness/weight ratio, mechanical energy absorption/weight unit, deformation and natural frequency, thermal transfer capacity, the breaking of the laminar flow, increased/optimized surface for chemical and/or electrochemical reaction etc.
