An extrusion die is provided with an external deckle assembly, an internal deckle assembly, or both. One embodiment provides an extrusion die having a wedge-actuated external deckle assembly. A seal member of the external deckle assembly moves to a sealed position in response to movement of the wedge in a first direction. Another embodiment provides an extrusion die with an internal deckle assembly having a deckle rod support system. The internal deckle assembly includes a deckle rod and a transversely elongated support engaged with the deckle rod to restrain the deckle rod against bending.

The invention provides a coextrusion feedblock. The feedblock has a flow adjuster comprising a plurality of independently rotatable adjustment segments. Actuators are coupled with respective adjustment segments of the flow adjuster, such that the segments can be rotated by operating the actuators. The invention also provides a coextrusion profiling insert assembly for mounting removably in a coextrusion feedblock.

In extrusion system includes an extrusion die and a deckle system. In one embodiment, the deckle system includes a deckle rod and a cam member operatively coupled to the deckle rod. A cam controller controls the cam member. The cam member cams with the deckle rod in response to actuation of the cam controller. The camming action forces the deckle rod to seal an end region of the extrusion die.

A layer multiplication device may include a housing and at least one layer multiplication insert positioned inside the housing. The housing may have an inlet configured to receive a flow stream, an outlet configured to discharge the flow stream, and a flow cavity extending between the inlet and the outlet. In operation, the layer multiplication insert may divide an incoming flow stream so as to multiply the flow stream into at least a first flow stream and a second flow stream. In some examples, the inlet provides an inlet flow volume equal to a cross-sectional area of the housing at the inlet multiplied by a length of the flow cavity, the flow cavity defines a cavity flow volume, and the cavity flow volume is equal to or greater than the inlet flow volume.

A layer multiplication device (100) may include a housing (102A, 102B) and at least one layer multiplication insert (106) positioned inside the housing (102A, 102B). The housing (102A, 102B) may have an inlet (108) configured to receive a flow stream, an outlet (110) configured to discharge the flow stream, and a flow cavity (112) extending between the inlet (108) and the outlet (110). In operation, the layer multiplication insert (106) may divide an incoming flow stream so as to multiply the flow stream into at least a first flow stream and a second flow stream. In some examples, the inlet (108) provides an inlet flow volume equal to a cross-sectional area of the housing (102A, 102B) at the inlet (108) multiplied by a length of the flow cavity (112), the flow cavity (112) defines a cavity flow volume, and the cavity flow volume is equal to or greater than the inlet flow volume.


Patent
Extrusion Dies Industries | Date: 2012-10-05

An adjustable feedblock configured for adjusting the thicknesses of each layer of the juxtaposed extrudates forming a laminate. The feedblock includes at least one pair of opposing combining planes and at least one pair of opposing extrudate distribution blocks that are removably disposed within the housing of the feedblock. As such, the combining planes and the extrudate distribution blocks partially define portions of the flow paths for the extrudates that form the laminate within the housing of the feedblock. A method for forming a laminate having juxtaposed layers of extrudates of adjustable thicknesses is also disclosed.
