Publication number: 20150104537Abstract: 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.Type: ApplicationFiled: October 10, 2013Publication date: April 16, 2015Applicant: Nordson Extrusion Dies Industries, LLCInventor: Jordan L. Sedivy

Publication number: 20130276895Abstract: 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.Type: ApplicationFiled: March 12, 2013Publication date: October 24, 2013Applicant: NORDSON EXTRUSION DIES INDUSTRIES, LLCInventors: Gary D. Oliver, Dale P. Pitsch, Michael K. Truscott

Publication number: 20130234359Abstract: 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.Type: ApplicationFiled: October 5, 2012Publication date: September 12, 2013Applicant: Extrusion Dies Industries, LLCInventors: John A. Ulcej, Michael K. Truscott

Publication number: 20130122131Abstract: 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.Type: ApplicationFiled: November 15, 2012Publication date: May 16, 2013Applicant: EXTRUSION DIES INDUSTRIES, LLCInventor: EXTRUSION DIES INDUSTRIES, LLC

Publication number: 20130020737Abstract: An extrusion device includes a sculpted extrusion die comprising a pair of mating die lips having sculpted surfaces and defining a die exit for an extrudate. The contour of the sculpted surfaces is substantially similar to the contour of a juxtaposed surface configured for receiving the extrudate from the die exit of the sculpted extrusion die. The sculpted extrusion die preferably comprises a die lip adjustment mechanism for adjusting a thickness of the extrudate exiting the die exit and the thickness of the extrudate received on the juxtaposed surface. The air gap between the die exit of the sculpted extrusion die and the juxtaposed surface preferably is substantially eliminated by adjusting the distance between the sculpted surfaces and the juxtaposed surface. A method of adjusting a thickness of a substantially continuous sheet of extrudate formed using an embodiment of the sculpted extrusion die of the invention is provided.Type: ApplicationFiled: July 20, 2011Publication date: January 24, 2013Applicant: EXTRUSION DIES INDUSTRIES, LLCInventor: John A. Ulcej
