Patent ID: 7097710

Claim:
An applicator for application of a substance onto a material traveling along a material feed direction comprising: a housing, said housing comprising: at least one housing inlet for the introduction of the substance into said housing; at least one housing channel for the distribution of the substance from said housing inlet, said housing channel being in fluid communication with said housing inlet; and at least one slot defining an elongated width extending along a direction that intersects the material feed direction, said slot being located on an extrusion-side surface of said housing, a rotatable valve, said valve comprising: at least one inlet groove for the further distribution of the substance, said inlet groove being in fluid communication with said housing channel; at least one inlet bore for the further distribution of the substance, said inlet bore being in fluid communication with said inlet groove; at least one valve reservoir to provide manifold functionality of the substance, said valve reservoir being in fluid communication with said inlet groove; at least one outlet bore for the further distribution of the substance, said outlet bore being in fluid communication with said valve reservoir; and at least one outlet groove in fluid communication with said outlet bore, wherein said outlet groove overlies and extends beyond said slot such that, as said valve is rotated, select portion of the outlet groove are placed in fluid communication with said slot along the width of said slot to form a continuous nonlinear extrusion pattern of the substance onto the material.
