Die lip for strip coating

A method for dispensing flowable material onto a supported substrate comprising:

• translating a flowable material through a first internal passage in a die block;
• translating the flowable material through a first array of orifices disposed through a die lip and in communication with the first internal passage, the die lip having a lateral dimension;
• directing the flowable material with a first edge disposed proximate one lateral side of the first array of orifices;
• and
• defining one edge of a first strip of flowable material on the supported substrate with the first edge.

A substrate comprising:

• a first planar side;
• at least one strip of flowable material having a substantially constant cross-sectional profile and edges substantially perpendicular to the substrate disposed on the first planar side;
• and
• wherein less than 65 percent of the substrate is covered by at least three strips of flowable material.

A die for dispensing a flowable material on a substrate comprising:

• at least one die block including a first internal passage;
• a die lip portion of the die block having a first plurality of orifices disposed through the die lip portion proximate to each other and in communication with the internal passage;
• a rod disposed substantially parallel to the lateral dimension of the lip;
• a first edge disposed on one lateral side of the first plurality of orifices;
• and
• a second edge disposed on the other lateral side of the plurality of orifices.

A method for disposing flowable material onto a supported substrate comprising:

• directing a flowable material through a first internal passage in a die block;
• directing the flowable material through a first array of orifices disposed through a die lip and in communication with the first internal passage;
• directing the flowable material with a first edge disposed proximate one end of the first array of orifices to define a first lateral edge of a first strip of flowable material on the supported substrate;
• directing the flowable material with a second edge disposed proximate the other end of the array to define a second lateral edge of the first strip of flowable material on the supported substrate;
• directing the flowable material through a second array of orifices disposed through the die lip and in communication with the first internal passage;
• and
• directing the flowable material with a third edge disposed proximate one end of the second array of orifices to define one lateral edge of a second strip of flowable material on the supported substrate;
• directing the flowable material using a fourth edge disposed proximate the other end of the second array of orifices to define a second lateral edge of the second strip of flowable material on the substrate;
• covering less than about 65 percent of the substrate with the first strip and the second strip;
• and
• maintaining a substantially constant cross-sectional profile of the first strip and the second strip.

A contact die for dispensing a flowable material on a substrate comprising:

• at least one die block including a first internal passage;
• a die lip portion of the die block having a lateral dimension, a first plurality of orifices disposed through the die lip portion proximate to each other and in communication with the internal passage so as to dispense flowable material as a single strip on the substrate;
• a rod disposed substantially parallel to the lateral dimension of the lip;
• a first means for guiding the lateral flow of the flowable material in a first direction;
• and
• a second means for guiding the lateral flow of the flowable material in a second, opposite direction.
